Use properties to find the sum or product 8×51

Answers

Answer 1
Answer:   8 ×51 = 8(50+1) = 8×50+08*1=400 + 08=408
Answer 2
Answer:

Answer:

8 \cdot 51 = 408

Step-by-step explanation:

use properties to find the sum or product 8×51

To use properties lets break 51 as 50 +1

8 times 51

8(50+1)

Now we use distributive property , Using this property we distribute 8 inside the parenthesis

8 times 50 is 400

8 times 1 is 8

400+8 = 408

So8 \cdot 51 = 408

Answer:

Step-by-step explanation:

1) 4x + 3 <= 3x - 5

Subtract 3 from both sides

4x + 3-3  <= 3x - 5 -3

4x  <= 3x - 8

Subtract 3x form both sides

4x - 3x <= 3x -3x - 8

x <= -8

Answer:

CHALLENGE ACCEPTED!!

Step-by-step explanation:

4x + 3 ≤ 3x - 5

4x - 3x ≤ -5 -3

x ≤ -8

sorry, cant draw the number line but hope the solution helps.

-2x > 6

-2x ÷ -2 > 6 ÷- 2

x > -3

1/8(3x - 16) < 4

3/8x - 2 < 4

3/8x < 4 + 2

3/8x < 6

x = 16

x - 3/2 ≥ -5

x - 3 ≥ -5 × 2

x - 3 ≥ -10

x ≥ -10 + 3

x ≥ 7
