Answer:
4
Step-by-step explanation:
For this, you need to find the scale factor of two sides that are already given to you.
So, we will have to use the hypotenuse and one of the legs to make sure there is an accurate scale factor.
Hypotenuse:
15 / 5 = 3
Leg:
6 / 2 = 3
____________
So the scale factor is 3.
Using the leg (with the x) we need to divide 12 by the scale factor (3) to give us what x is equal to.
12 / 3 = 4
So, the answer is 4.
Two stores sell CDs in packages, as shown in the table below.
CD Prices at Store A
Number of CDs in Package
1
12
20
45
Cost
$0.70
$8.40
?
$31.50
CD Prices at Store B
Number of CDs in Package
1
20
30
65
Cost
$0.60
?
$18.00
$39.00
If the rate at each store is constant, which statement correctly compares the cost of a package containing 20 CDs?
The cost at Store A is $2.00 greater than at Store B.
The cost at Store B is $2.00 greater than at Store A.
The cost at Store A is $1.00 greater than at Store B.
The cost at Store B is $1.00 greater than at Store A.
Answer:
Step-by-step explanation:
If each CD at store A costs $.70, then 20 of them will cost 20(.7) = $14.
If each CD at store B costs $.60, then 20 of them will cost 20(.6) = $12.
The correct statement is that The cost at Store A is $2.00 greater than at Store B.
Luigi uses 39 cups of flour for every 6 pizzas he makes. How many cups of flour does he need to make 4 pizzas? If he uses 13 cups of flour how many pizzas can he make?
Answer:

Solve the following system. The solution set {( , ), ( , )}.
3 (x - 2) = 2 (x - 3)
Answer:
x = 0
Step-by-step explanation:
Given equation to us is ,
[tex]\sf\implies 3 (x - 2 ) = 2( x - 3 )[/tex]
And we need to find out the value of x.
Step 1 : Open the parentheses :-
[tex]\sf\implies 3x - 6 = 2x - 6 [/tex]
Step 2: Put all variables on one side :-
[tex]\sf\implies 3x - 2x = -6+6 [/tex]
[tex]\sf\implies\boxed{\bf x = 0 }[/tex]

By how much does the price of a ticket for the gold section exceed the price for a ticket for the silver section?
Answer:
$8
Step-by-step explanation:
This system of equations relates the ticket price, in dollars, for seats in the silver (x) and gold (y) sections at a rock concert. x + 2y = 82 3x + y = 96 By how much does the price of a ticket for the gold section exceed the price for a ticket for the silver section?
Two equations are presented in this question
x + 2y = 82 equation 1
3x + y = 96 equation 2
Multiply equation 1 by 3
3x + 6y = 246 equation 3
subtract equation 2 from 3
5y = 150
y = 30
Substitute for y in equation 1
x + 2(30) = 82
x = 82 - 60
x = 22
difference in price = 30 - 22 = $8
x =

The average human body contains about 40 L of water. What is the total amount of water contained in the 6.4 billion people in the world? Show each step in your solution. Express your answer in scientific notation.
Answer:
2.56 * 10^11 L
Step-by-step explanation:
1 body has 40 L
Thus, the amount in 6.4 billion would be;
40 * 6.4 * 10^9
= 256 * 10^9
= 2.56 * 10^2 * 10^9
= 2.56 * 10^11 L

One number is 10 less than three times a second number. If their sum is 46, find the larger of the two numbers.
Answer:
32
Step-by-step explanation:
Number 1 =x
Number 2 =(3x-10)
number 1 + number 2 =46
x+(3x-10)=46
4x=56
x=14
Number 1 =x=14
Number 2=3x-10
3(14)-10
32
Number 1 (14)+Number 2 (32)=46

Does the graph shown below represent y as a linear function of x?
Answer: No, it is not a linear function
Explanation:
We can see that it's a function because it passes the vertical line test, but it's not linear. To be linear, it needs to be one single straight line only (instead of composed of multiple pieces of different straight lines). This graph is considered a piecewise function.
So if your teacher asked "is this a function?" then the answer would be "yes". However, the "linear" portion is what makes the final answer "no".

$975, and there is 7 percent sales tax on the purchase.
How much is the sales tax?
Answer:
$68.25
Step-by-step explanation:
To get the sales tax, you must notice that the sales tax is 7% of 975.
That is equal to:
975 × 0.07
0.07 is equal to 7%, or [tex]\frac{7}{100}[/tex].
The answer to the equation is 68.25.
The length of a rectangle is 3
more than 5 times its width.
Find the perimeter of this
rectangle if its area is 92 m2.
[?]m
Let W = width then length = 5W + 3
Area = W(5W + 3) = 5W2 + 3W = 92
5W2 + 3W - 92 = 0 has a negative root and the positive root = 4 (by the quadratic formula)
The length = 23 and the perimeter = 2(L + W) 2 * 27 = 54
