Question

1. solve the inequality 8x ≤ 48

Answer 1

Answer:

Part 1: A. x ≤ 6

Part 2: B. x > 13

Part 3: C. x ≤ 42

Part 4: Option C and D

Step-by-step explanation:

Given the questions of inequality in parts we have to solve these inequality.

Part 1:  8x ≤ 48

Dividing by 8 on both sides, we get

$\frac{8x}{8}\leq \frac{48}{8}$

$x\leq 6$

Option A is correct.

Part 2:  10 + x > 23

Subtracting 10 from both sides, we get

$10+x-10> 23-10$

$x> 13$

Option B is correct.

Part 3: x - 14 ≤ 28

Adding 14 on both sides, we get

$x-14+14\leq 28+14$

$x\leq 42$

Option C is correct.

Part 4: x - 4 ≥ 0

we have to choose the values which can be submitted for x to make the inequality x - 4 ≥ 0 true

Adding 4 on both sides

x - 4+4 ≥ 0+4

x ≥ 4

Since 4 and 18 are only two numbers ≥ 4.

Hence, the correct option is C and D

Answer 2

1.8x≤48
x≤6 (A)
2.10+x>23
x>13(B)
3.x-14≤28
x≤42(C)
4.There are no y in the inequality
5.x-4≥0
4=4,18≥4
So C and D are the answer
