A photographer is making an enlargement of a color portrait. If the original portrait is 11 inches by 14 inches and he wants to make the new width 14 inches, about how long should the enlarged length be?

Answers

The width of the original is 11 inches.

The ratio of the width is 14/11

Set up a ratio for the new length:

14/11 = 14/X

Cross multiply:

11x = 196

Divide both sides by 11:

x = 196/11

x = 17.8 inches. (Rounded to the nearest tenth)

Answer:

Original width: 11 inches.

ratio: 14/11

Which represents the solution for the inequality -7x +42 < or equal to 28 ?

A. x is greater than or equal to -10
B. x is less than or equal to -10
C. x is less than or equal to 2
D. x is greater than or equal to 2

Answers

Answer:

The answer is D.

Step-by-step explanation:

If we plug in the first two answers (-10):

-7(-10) +42 < or equal to 28

Two negatives equal a positive so: 70+42=112 which is not less than or equal to 28.

So both A and B are not correct, because -10 results in a number GREATER than 28.

This means it has to be either C or D and both use the number +2, so we'll try +1 to solve for C, and +3 to solve for D.

For C: -7(1) +42 < or equal to 28

-7+42=35 which is NOT less than or equal to 28

For D: -7(3) +42 < or equal to 28

-21+42=21 which IS less than or equal to 28

Each number greater than 2 will give you a larger number being subtracted from 42, and that result will always be less than or equal to 28.

The answer is D x is greater than or equal to 2
