A. 7
B. 50
C. 14
D. 42

Answers

Fourteen is 28% of B) 50

Why, you ask? Let's see -

Let the unknown number be n, for 'number'.

Let's put the unknown n next to 28%

.28n% = 14

(Think, what times .28 equals 14? Look below to find out! ↓ )

Let's now do the opposite of the actual equation - divide the two known numbers by each other -

.28 ÷ 14 = 50

When in doubt, check your answer:

To check this, we would do the opposite - Multiplication

Multiply .28 by 50 to get 14 (At least you should get 14)

.28 × 50 DOES EQUAL 14! We were right! :D

27. Solve the inequality
3(3x + 7) > 4-8(4 + 5x).

Answers

Answer:

x > -1

Step-by-step explanation:

Step 1: Distribute

3(3x + 7) > 4 - 8(4 + 5x)

(3 * 3x) + (3 * 7) > 4 + (-8 * 4) + (-8 * 5x)

9x + 21 > 4 - 32 - 40x

Step 2: Combine like terms

9x + 21 > 4 - 32 - 40x

9x + 21 > -28 - 40x

Step 3: Add 40x to both sides

9x + 21 + 40x > -28 - 40x + 40x

49x + 21 > -28

Step 4: Subtract 21 from both sides

49x + 21 - 21 > -28 - 21

49x > -49

Step 5: Divide both sides by 49

49x / 49 > -49 / 49

x > -1

Answer: x > -1
