Answer:

The value of x = -13

Step-by-step explanation:

Given the expression

$\frac{0.2x+1}{2}=-0.8$

Multiply both sides by 2

$\frac{2\left(0.2x+1\right)}{2}=2\left(-0.8\right)$

simplify

$0.2x+1=-1.6$

Subtract 1 from both sides

$0.2x+1-1=-1.6-1$

Simplify

$0.2x=-2.6$

Divide both sides by 0.2

$\frac{0.2x}{0.2}=\frac{-2.6}{0.2}$

Simplify

$x=-13$

Therefore, the value of x = -13

Find two consecutive even integers such that the lesser added to three times the greater gives a sum of 46.

kvv77 [185]

N; n + 2 - the two consecutive even integers

n + 3(n + 2) = 46
n + 3n + 6 = 46 |subtract 6 from both sides
4n = 40 |divide both sides by 4
n = 10

n + 2 = 10 + 2 = 12

Answer: 10 and 12.
