Carl is drawing blueprints for a new building. Although the building will be 40 feet (480 inches) tall, his drawing is only 10 inches tall. Assuming the drawing is to scale, what is the ratio of the building to the drawing

48:1

Step-by-step explanation:

In this case we know the actual size and the size in the drawing therefore we can calculate its scale.

What we must do is divide the actual size by the size in the drawing. We know the actual size is 480 inches and in the drawing the size is 10 inches, so:

480/10 = 48

Which means that the relationship between the real and the drawing is 48:1

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
