13.5 feets

1 inch

Step-by-step explanation:

Given :

Blueprint length (in.) __2 4 6 8 10 12

Actual length (ft) 3 6 9 12 15 18

From the data:

Blueprint : actual

2 in : 3 feets

Length of wall on blueprint = 9 inches

Actual length of wall :

2 inches = 3feets

9 inches = x

Cross multiply

2x = 27

x = 27 /2

x = 13.5 feets

B.)

For actual width = 1.5 feets

2 inches = 3feets

x = 1.5 feets

3x = 2 * 1.5

3x = 3

x = 3/3

x = 1 inch

answer: a and c are correct

step-by-step explanation:

the +5 is the vertical translation

the added negative symbol in front is the reflection over the y-axis

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
