Answer:

14 correct and 11 wrong

Step-by-step explanation:

If you got a 56% , we need to change this to decimal form 56% = .56

This is the percent you got right

.56* 25 = 14

You got 14 questions right

To determine the number of questions you got wrong, take the total number of questions minus the number you got right.

25-14 =11

You got 11 wrong

Steve increases his math average by 9 points over a period of 15 weeks. How many points per week did he average?
Anna71 [15]
You find it by looking for the key words "points per week"

per means basically divide. POINTS DIVIDED BY WEEKS

so 9 divided by 15....
 but when they ask "did he average..... just in case, write the answer of 9/15 rounded, AND as the unrounded decimal..... or this is a whole different topic, and this might not be the answer your teacher is looking for.... but that's that.

Every Halloween, trick-or-treaters love going to Erica's house to see her spooky decorations and get some of her delicious caram
ra1l [238]

Answer:

y=3x

Step-by-step explanation:

Let

x ----> the number of kids in a group

y ----> the total number of caramel chews Erica gives to that group

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form k=\frac{y}{x} or y=kx

Find the value of the constant of proportionality k

take a ordered pair from the data in the table and determine the value of k

For x=2, y=6 ----> k=\frac{y}{x} ----> k=\frac{6}{2}=3\ caramels/kid

therefore

y=3x
