Answer:
a=5 and b=9
Step-by-step explanation:
(x, y) = (s, t) => x=s and y=t
Hence, a+3=b-1 and b-2=2a-3, solving we get a=5 and b=9
A phone call costs $0.65 for the first 3 minutes and $0.15 for each additional minute. If the total charge for the call
was $5.00, how many minutes was the call?
Answer:
31 Minutes
Step-by-step explanation:
4.78 = 0.15 + 0.58
0.15m = 4.78 - 0.58
m = 4.78 - 0.58 divided by 0.15 = 28 minutes
So in total we have 28 + 3 = 31 minutes

A population of bacteria contains 150 bacteria in generation 1 and triples in
population every generation. This sequence represents the number of
bacteria for the first few generations:
150, 450,1350, ...
What is the explicit formula for the number of bacteria in generation n?
Answer: bn= 150*3^(n-1)( bn is a quantity of bacteria in generation n)
Step-by-step explanation:
It looks like geometrical sequence, each next generation is three times greater than previous one. So the r of this sequence is 3.
The first generation has 150 representatives, so b1=150
The formula of geometrical sequence is bn=b1*r^(n-1)
(in our case bn is a quantity of bacteria in generation n)
so bn= 150*3^(n-1)( bn is a quantity of bacteria in generation n)
i need help!!!! what does x equal?
Answer:
17
Step-by-step explanation:
Answer:
x = 17
Step-by-step explanation:
We can find the missing angle inside the triangle by doing 180 - 94 = 86.
Every triangle has 3 angles that add up to equal 180 so we can set these three angles to equal 180.
60 + 86 + 2x = 180
146 + 2x = 180
Subtract 146 from both sides
2x = 34
Divide by 2 to isolate x
x = 17

Mary lives 1 3/4 miles from school. She rode her bycycle to school and back for 5 days. Which expression shows how to estimate the number of miles she rode?
The expression which represents the number of miles Mary rode in 5 days is 5*(2 + 2).
What is mixed fraction?A fraction represented with its quotient and remainder is a mixed fraction.
What is expression?An expression is a number, a variable, or a combination of numbers and variables and operation symbols.
According to the given question.
Distance between Mary's house and school = [tex]1\frac{3}{4} =\frac{7}{4}[/tex]
Number of days Mary rode her bicycle to school and back = 5
⇒ Distance travelled by Mary in one day = [tex]2(\frac{7}{4} )=\frac{7}{2}[/tex]
Therefore, the expression which represents the number of miles she rode in 5 days = [tex]5(\frac{7}{2} )=\frac{35}{2}=17.5 miles[/tex] ≈ 20 miles
Hence, the expression which represents the number of miles Mary rode in 5 days is [tex]5[/tex] *(2+2).

Hey there! I'm happy to help!
The equation y=0.5x simply means that Joseph is hiking 0.5 miles every hour. This is because the x value is the independent variable or the thing you change, which in this case is the time you take hiking. The distance, the y-value, is dependent on that time.
Now, let's look at Kelly's graph. This graph isn't a grid, so we will have to eyeball some of the numbers on the graph. It appears that after 10 hours, Kelly has traveled eight miles. This is because if you go up from the 10 and meet the line and then go to the left. you will be about at the line right below the 10 on the y-axis, and if you count the lines, you will see that we are counting by 2, so it has to be eight.
So, we see that Kelly takes 10 hours to go eight miles. We know that Joseph's distance is half of his time (4 hours would be 2 miles, 6 hours would be 3 hours, etc.)
So, if we say that Joseph hikes for ten hours, he will have hiked five miles as that is half of ten. We see, though, that Kelly made it eight hours in that time, so Kelly is going faster here.

What is 6 tenths, 2 hundredths, 8 thousandths in standard form?
A.0.0628 B.0.628 C.6.28 D.628
Answer:
B: 0.628
Step-by-step explanation:
Place value rules.
The value of each digit in a number is known as the place value. The number that has 6 tenths, 2 hundredths, and 8 thousandths can be written in the standard form as 0.628. The correct option is B.
What is the place value of a digit in a number?The value of each digit in a number is known as the place value. The 5 in 350, for example, represents 5 tens, or 50, whereas the 5 in 5,006 represents 5 thousand, or 5,000. It is critical that children that while a digit can be the same, its value is determined by its position in the number.
Identification of the place value of a digit in a number:
The place values on the left of the decimal point start as ones, tens, hundreds, and so on.The place value on the right of the decimal point starts from the point and goes to the right as tenths, hundredths, and so onThe tens mean multiply by 10The tenth means the tenth part of that digit which is that digit divided by 10Given 6 tenths, 2 hundredths, 8 thousandths, this can be written in the standard form as,
Standard form = 0.6 + 0.02 + 0.008 = 0.628
Hence, the number that has 6 tenths, 2 hundredths, and 8 thousandths can be written in the standard form as 0.628.

An insurance company sells a homeowner's insurance policy that is $600 per year per policy. The insurance company predicts that the probability of having a home being damaged in the area it sells this policy is about 11,000. If the home is damaged, the insurance company expects to pay $400,000 to the homeowner. If the company were to sell 250 policies, how much money can it expect to gain or lose
Answer:
profit of $140,910
there is a missing number I will assume that the probability is 1 in 11,000
company expected revenue per policy = $600
companies expected expense = 400,000 * (1/11,000) = -36.36
profit per policy = $536.64
$536.64*250 = $140,910

if the question ia right then answer comes to a point as 6<10A Cheetah running at 61 miles per hour is chasing an American Antelope that is running
at a rate of 1583 meters per minute.
Which animal is running at a faster rate?
Answer:
Cheetah
Step-by-step explanation:
American Antelope's speed = 94980 meters per hour
= 59 miles per hour
The Cheetah is faster than the American Antelope
Answer:
Step-by-step explanation:
The American Antelope is going at a rate of 1583 meters / minute
1583 m [ 1 km / 1000 m ] = 1.583 km / minutes
In an hour, the Antelope will go 1.583 km / minute * 60 min / hour
1.583 * 60 = 94.98 km / hour
The cheetah is going 61 miles / hour * 1.6 km / mile = 97.6 km/hour

Find the x-intercept and y-intercept of the line.
4x+5y= -20
Answer:y-intercept = -20/5 = -4 x-intercept = -20/4 = -5
Step-by-step explanation:
Answer:
x- intercept = - 5, y- intercept = - 4
Step-by-step explanation:
The x- intercept is where the line crosses the x- axis.
The y- coordinate of any point on the x- axis is zero
Substitute y = 0 into the equation and solve for x
4x + 5(0) = - 20
4x = - 20 ( divide both sides by 4 )
x = - 5 ← x- intercept or (- 5, 0 ) in coordinate form
The y- intercept is where the line crosses the y- axis
The x- coordinate of any point on the y- axis is zero
Substitute x = 0 into the equation and solve for y
4(0) + 5y = - 20
5y = - 20 ( divide both sides by 5 )
y = - 4 ← y- intercept or (0, - 4 ) in coordinate form

Option c = 6Step-by-step explanation:
Given,
7+5(x-3)=27+5(x−3)=22
(Taking one of the equation)
=> 7 + 5(x - 3) = 22
=> 7 + 5x - 15 = 22
=> 5x = 22 + 15 - 7
=> 5x = 30
[tex] = > x = \frac{30}{5} [/tex]

help me with my homework
Answer:
a because I dont know why but some one told me it was this
Answer: A. There are three terms
Concept:
In an algebraic expression, there are several specific terms:
Constant: the individual number that has no variable with it, or in east word, it is isolated.Variable: any unknown value, which is usually presented by alphabets.Coefficients: the numbers that are bounded with a variable, usually in front of a variable.Terms: the number of individuals present in the expression, which is constants and [variable + coefficients].Like terms: terms that have the same variables and powers.If you are still confused, you may refer to the attachment below for a graphical explanation.
Solve:
a. There are three terms. [tex]\boxed{FALSE}[/tex]
- 14b
- -7
- 8b
- b
There are in total four individuals, which means there are four terms.
b. There is one constant term. [tex]\boxed{TRUE}[/tex]
- 14b is a [variable + coefficient]
- -7 is a [constant]
- 8b is a [variable + coefficient]
- b is a [variable]
Therefore, there is one constant term.
c. The coefficients are 14, 8, and 1 [tex]\boxed{TRUE}[/tex]
- 14b →→→ 14 is the [coefficient]
- -7 →→→ is a [constant]
- 8b →→→ 8 is the [coefficient]
- b →→→ 1 is the [coefficient]
Therefore, 14, 8, and 1 are coefficients.
d. Three of the terms are like terms [tex]\boxed{TRUE}[/tex]
- 14b →→→ b is the [variable]
- -7 →→→ is a [constant]
- 8b →→→ b is the [variable]
- b →→→ b is the [variable]
Since 14b, 8b, and b share the common variable, there are three like terms.
Hope this helps!! :)
