Answer:
(x, y) = (1, -9)
Step-by-step explanation:
y = -9x
-8x-6y = 46
By substituting the value of y (first equation) into the second equation, we get,
-8x - 6*(-9x) = 46
-8x + 54x = 46
46x = 46
x = 1.
So, y = -9

Sara and Fiona have played 53 tennis matches.
Sara has won 29 times.
Fiona won the rest.
a) Estimate the probability that Sara wins.
b) Estimate the probability that Fiona wins.
Answer: Sara = 29/53
Fiona = 24/53
Step-by-step explanation: because that amount is how much they have won and how much its out of so for example ‘i played 26 games i only won 17 and John won the rest’ the probability that i win is
17/26 and Johns would be 9/26

Answer:
x=21/5, also known as 4.2
Step-by-step explanation:
5x:9 = 7:3
Solve it like a proportion and get any of these answers
5x/9 = 7/3
cross product property
3(5x) = 63
15x = 63
x = 63/15 = 21/5 in fraction form = 4.2 in decimal form
A person who weighs 200 pounds on Earth would weigh about 32 pounds on the moon. Find the weight of a person on Earth who would weigh 15 pounds of the moon
Answer:
93.75 pounds
Step-by-step explanation:
Set up a proportion where x is the weight of a person on Earth:
[tex]\frac{200}{32}[/tex] = [tex]\frac{x}{15}[/tex]
Cross multiply and solve for x
32x = 3000
x = 93.75
So, the person would weigh 93.75 pounds on Earth
On Earth, a person weighing 93.75 pounds would weigh around 15 pounds on the moon.
What is the proportion?A mathematical assessment of two numbers is called a proportion. If two sets of provided numbers rise or fall in the same relation, then the ratios are said to be directly proportional to each other.
If a person who weighs 200 pounds on Earth would weigh about 32 pounds on the moon, we can set up the following proportion to find the weight of a person on Earth who would weigh 15 pounds on the moon:
200 pounds : 32 pounds = x pounds : 15 pounds
200 pounds / 32 pounds = x pounds / 15 pounds
⇒ 200/32 = x/15
Apply the Cross-multiplication operation, we get:
⇒ 200 × 15 = 32 × x
Solving for x, we get:
⇒ x = (200 × 15) / 32
⇒ x = 3000/32
Apply the division operation
⇒ x = 93.75 pounds
Therefore, a person who weighs 93.75 pounds on Earth would weigh about 15 pounds on the moon.

The line of best fit for a scatterplot is shown what is the equation of this line of best fit in slope intercept form?
(pic provided)
1. y=-6x+3/4
2.y=6x+3/4
3. y=-3/4x+6
4. y=3/4x+6
Answer:
3. y=-3/4+6
Step-by-step explanation:
The y-int is 6, so you can already cross out the first two answers. Then, you know the slope is negative because the line is going downward, so -3/4 has to be the slope bc it is negative.
Answer:
y=-3/4x+6
Step-by-step explanation:
the y/intercept is (0,6) because that is the point where the line crosses the y-axis
knowing that use the point (0,6) and (4,3) to find the slope use rise over run so it goes up 3 and right 4
using the slope intercept equation y=mx+b it is y= -3/4+6
it is negative because its going downward

What type of solution represents the system x + y = 8 2x + 2y = 16
Answer:
Subtract y from both sides of the equation.
x=8−y
2x+2y=16
Replace all occurrences of x with 8−y in each equation.
16=16
x=8−y
Remove any equations from the system that are always true.
x=8−y

3. If you buy a new car for $6,000 which depreciates at 4%/year,
what will the value be after 3 years?
Answer:
$5,308.42
Step-by-step explanation:
(see attached for reference)
recall that the formula for Depreciation
is given by
A = P ( 1 - r)^t,
where
A = final amount
P = principal amount = given as $6,000
r = depreciation rate = given as 4% = 0.04
t = time in years = given as 3,
Simply substitute these into the equation to get:
A = P ( 1 - r)^t
= 6000( 1 - 0.04) ^ 3
= 6000 (0.96)^3
= $5,308.42

Step-by-step explanation:
Adrian is drawing a map to show the directions from his house to his grandmother's house. He uses a scale of 1 1/2
inches represents 12 miles. If the distance from his house to his grandmother's house is 36 miles, how long is the drawing
on the map?
The length of the drawing on the map for 36 miles is given by the equation A = 4 1/2 inches
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the number of miles be = 12 miles
So , 12 miles on the drawing represents = 1 1/2 inches
Now , the number of miles = 36 miles
12 x 3 = 36 miles
And , 36 miles on the drawing represents = 3 x 12 miles on the drawing
Substituting the values in the equation , we get
36 miles on the drawing represents A = 3 x ( 1 1/2 )
On simplifying the equation , we get
36 miles on the drawing represents A = 4 1/2 inches
Hence , the value on the drawing is 4 1/2 inches

Answer:
A = 250
B = 75
C = 40
Step-by-step explanation:
Apparently, we're supposed to assume that the "health gained" is proportional to the "time in circle." The constant of proportionality is 100/4 = 25. This means all the numbers in the right column are 25 times those in the left column:
A = 25·10 = 250
B = 25·3 = 75
C·25 = 1000 ⇒ C = 40 . . . . . note these numbers are 10 times those in the first row

Answer: x = 4
Step-by-step explanation:
since it is showing us that the angles are congruent, we know that the smaller triangle is just a scaled-down version of the larger one. in other words, it is the EXACT SAME triangle, just slightly smaller.
so, i redrew them next to each other, so i could compare them easily.
i looked at the corresponding sides that were given, and realized that the side that is 10 on the larger triangle is equal to 5 on the smaller triangle. the side that is equal to 6 on the larger triangle is equal to 3 on the smaller triangle. this concludes that the smaller triangle is exactly half the size of the larger triangle!
so, i figured (using logic) that x must equal 4, simply dividing its corresponding side (with a measure of 8) in half.
hope this helps! xoxo

What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
From the figure,
3x + 46 + 14 = 90
Now,
Simplifying.
3x + 60 = 90
Subtracting 60 on both sides.
3x = 90 - 60
3x = 30
Dividing 3 into both sides.
x = 10
Thus,
The value of x on the given figure is 10.

Answer:
C. 75 cu cm
75 cm³
Step-by-step explanation:
Volume of the cake when Salim bought it = length × width × height
= 15 cm × 6 cm × 5 cm
= 450 cm³
Volume of the cake after Salim cut a piece = length × width × height
= 12.5 cm × 6 cm × 5 cm
= 375 cm³
volume of the piece that Salim ate = Volume of the cake when Salim bought it - Volume of the cake after Salim cut a piece
= 450 cm³ - 375 cm³
= 75 cm³
volume of the piece that Salim ate = 75 cm³

Trina is 53 3/ 4 inches tall. Jillian is 1 1/ 2 inches taller than Trina and Jane is 1 1 /5 inches taller than Jillian. How tall is Jane?
Answer: Jane is 56 9/20 inches tall
Step-by-step explanation:
Trina 's height = 53 3/4inches
Jiliam height = 1 1/ 2 inches taller than Trina which means
53 3/4inches + 1 1/ 2 inches
Add whole numbers to whole numbers and fractions to fractions
53+ 1 3/4 + 1/2
54 (3+ 2)/4 = 54 5/4 = 54+ 1 1/4 = 55 1/4 cm
Jane is 1 1 /5 inches taller than Jillian which means
55 1/4 cm +1 1 /5 inches
Add whole numbers to whole numbers and fractions to fractions
55 + 1 1/4 + 1/5
56 (5 + 4)/20 = 56 9/20
