Solve the equation for x.
x/5 = -8
Answer:
x = -40
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other.
Multiply 5 to both sides of the equation:
(x/5) * 5 = (-8) * 5
x = -8 * 5
x = -40
x = -40 is your answer.

Assume your phone bill averages $165 a month and you have a car payment that is $505 per month. You also spend about $150 a week on food. How much are your monthly expenses?
Answer:
1270 a month on expenses
Answer:
1270 a month
Step-by-step explanation:
There is 4 weeks for month so you multiply 150 x 4 = 600 and just add 165 and 505 which is equal to 1270
Use the Distributive Property to write each expression as an equivalent expression. Then evaluate it.
7(7 – 9)
Question 15 options:
Answer: The answer is 40.
Step-by-step explanation: 7(7-9) when you use distributive property you will use the 7 outside the parenthesis. Multiply the property inside. then you will get 49-9. Then you will solve it and get the answer 40.
the sum of two numbers is 75. the first is 9 more than 5 times the second. find the first number
Answer:
1st number is 64
Step-by-step explanation:
Lets start by making the words into equations.
So the 1st plus the 2nd is 75:
1st+ 2nd= 75
Now the tricky part. The 1st is 9 more than 5 times the 2nd. The key word 'times' means multiplication, we we will have 5 x 2nd somewhere in our equation. The '1st is 9 more than' part tricks us into thinking we will have 1st plus 9, BUT WE WON'T because it isn't 9 more, its 9 more THAN. This means we will get.
1st= 5 x 2nd +9
To make this a little cleaner, I will have the 1st = X and the 2nd= y.
x+y=75
x=5y+9
We can substitute the bottom equation into the top equation.
5y+9+y=75
Combine like terms
6y+9=75
Solve for Y by getting y alone.
6y+9=75
6y=66
y=11
Then we can take our value of y and plug it back into either equation to solve for X. The top equation is the easiest.
x+11=75
Isolate x to solve for x
x=64
And we established that x= the 1st number, so the 1st number is 64
Under her cell phone plan, Myesha pays a flat cost of $35 per month and $5 per gigabyte. She wants to keep her bill under $55 per month. Write and solve an inequality which can be used to determine g, the number of gigabytes Myesha can use while staying within her budget.
Answer:
4gb
Step-by-step explanation:
$55-$35 =$20
after paying min monthly cost she has $20 left before reaching cap of $55
at $5 per gb she can buy 4 gb for $20
The number of gigabytes she can use while staying within her budget less than 4 gigabytes.
It is required to find the umber of gigabytes.
What is arithmetic?Arithmetic is the branch of mathematics that deals with the study of numbers using various operations on them. Basic operations of math are addition, subtraction, multiplication and division. These operations are denoted by the given symbols.
Given:
Let the number of gigabytes be represented be g
Nicole pays a flat cost of $35 per month and $5 per gigabyte. She wants to keep her bill under $55 per month.
Under $55 = less than (<) $55
According to given question we have,
$35 + $5 × g < 55
35 + 5g < 55
compare like terms and simplify we get,
5g < 55 - 35
5g < 20
g < 20/5
g < 4 gigabytes
Therefore, the number of gigabytes she can use while staying within her budget less than 4 gigabytes.

Does Margaretta have enough storage boxes to fit a full cord?(enter yes or no)
If not, how many storage boxes would she need to fit a full cord
Answer:
no
she needs 6 boxes
Step-by-step explanation:
multiply the dimensions of the box which is 24.
multiply it by 3 because she has 3 boxes.
24 times 3 is 72
72≠128
part 2:
divide 128 by 24 which is 5.333
you cant have a third of a box so round it up to 6 .

The value of x for the given equation -3x = y + 51 such that the value of y is -9 will be -14.
What is the equation?An equation is said to be linear if the maximum power of the variable is consistently unity.
More than one variable may be present inside a linear equation.
A formula known as an equation uses the same sign to denote the equality of two expressions.
As per the given equation,
-3x = y + 51
At y = -9
-3x = -9 + 51
-3x = 42
x = -14
Hence "The value of x for the given equation -3x = y + 51 such that the value of y is -9 will be -14".

Question 2
Solve for the variable cin this equation:
a(c + b) =d
A. C= d-ab/a
B. C= d+ab/a
C. C= ab- d/a
D. d-ab/b
Answer:
A. C = (d-ab)/a
Step-by-step explanation:
a(c + b) = d
a(c + b)/a = d/a
c + b = (d/a)
c = (d/a) - b
a(c + b) = d
ac + ab = d
ac = d - ab
ac/a = d/a - ab/a
c = (d/a) - b

21 and 7.
let the greater number be x and smaller number be y.
it is given that x = 3y.
it is also given that 4y + 5x = 133.
=> 4y + 5 * 3y = 133.
=> 4y + 15y = 133

find the least common multiple of the denominators.
which is 12
so 1/4=3/12
2/3=8/12
1/2=6/12
so 3/12- 8/12 - 6/12 = -11/12
so there is 1/12th pieces left after they all ate their portions of the pie

If ∠=°, what is the measure of each of the other angles?
Answer:
Angles 2, 4, 6 & 8 are 118 degrees and angles 1, 3, 5 & 7 are 62 degrees.
Step-by-step explanation:
∠4 ≅ ∠2 by the Vertical Angle Theorem.
∠4 ≅ ∠8 by the Corresponding Angle Theorem.
∠4 ≅ ∠6 by the Alternate Exterior Angle Theorem.
∠4 is supplementary to ∠1 and ∠4 supplementary to ∠3 by the Linear Pair Postulate.
∠4 is supplementary to ∠5 because ∠4 ≅ ∠2 (explained above) and ∠2 supplementary to ∠5 by the Same-Side Interior Angle Theorem.
∠4 is supplementary to ∠7 by the Same-Side Exterior Angle Theorem.
What is the equation of this line in standard form?
A: 9x−8y=23
B: 8x−9y=23
C: 8x−9y=−23
D: 8x−7y=−25
Answer:
B:8x-9y=23
Step-by-step explanation:
First find the slope:
m= y2-y1/x2-x1
y2 is 3
y1 is -1
x2 is 1/2
x1 is -4
3-(-1) is 4
1/2-(-4) is 9/2
Now the equation looks likes this:
4 / 9/2
Which can be rewritten as
4*2/9
Thus the slope is 8/9
So the equation is
y=8/9x+b
Now you can substitute to find the y-intercept:
(you can do either (-4,1) or (1/2,3)
I am going to do (1/2,3) since it is easier
3=8/9(1/2)+b
Simplify:
3=4/9+b
Subtract 4/9 on both sides:
b=23/9
Thus the equation is
y=8/9x+23/9
Multiply 9 on both sides:
9y=8x+23
Subtract 8x on both sides:
8x-9y=23

Here is a triangle:
(a) Work out the size of the angle marked a.
(b) Work out the size of the angle marked b.
Answer:
a.) 130°
b.) 70°
Step-by-step explanation:
For a given triangle
a.)The sum of all angles on a straight line is equal to 180°
Now,
50° + a = 180°
Subtract 50° from each side we get,
50° - 50° + a = 180° - 50°
a = 130°
Thus, The size of the angle marked a is 130°
b.)The sum of all angles in a triangle is equal to 180°
Now,
b + 50° + 60° = 180°
b + 110° = 180°
Subtract 110° from both side we get,
b + 110° - 110° = 180° - 110°
b = 70°
Thus, The size of the angle marked b is 70°
