Solve for x 1 7 1 2 х Your answer

ki77a [65]

Answer:

x = 4

Step-by-step explanation:

3x -5 = -2 + 9

-2 + 9 = 7 so now its 3x - 5 = 7

add 5 to the -5 so it cancels itself out. then add the 5 to 7 so it become 12. the you have 3x = 12

divide 12 ÷ 3 = 4

x = 4

What is (n+2) / -8=-4

Travka [436]

$\frac{n +2}{-8} =-4$ Multiply -8 on both sides

$\frac{n +2}{-8} (-8)=-4(-8)$

n + 2 = 32 Subtract 2 on both sides

n + 2 - 2 = 32 - 2

n = 30

Pls help me with this

Answer:

x = 1.5

Step-by-step explanation:

Given

$\frac{x}{2} \geq 0.75$

$\frac{x}{2} < 2.5$

Required

Find the value of x.

First, the inequalities need to be rewritten and merged;

if $\frac{x}{2} \geq 0.75$ , then

$0.75 \leq \frac{x}{2}$

Multiply both sides by 2

$2 * 0.75 \leq \frac{x}{2} * 2$

$1.5 \leq x$

Similarly;

$\frac{x}{2} < 2.5$

Multiply both sides by 2

$2 * \frac{x}{2} < 2.5 * 2$

$x < 5$

Merging these results together; to give

$1.5 \leq x < 5$

This means that the range of values of x is from 1.5 to 4.9999....

From the question, x is the smallest rational number; from the range above ( $1.5 \leq x < 5$ ), the minimum value of x is 1.5 and 1.5 is a rational number;

Hence, x = 1.5
