Which inequality has –12 in its solution set? A B C D x + 6 less-than negative 8 x + 4 greater-than-or-equal-to negative 6 x min

Vlad1618 [11]

Answer:

The correct answer is D. x + 5≤ - 4

Step-by-step explanation:

Let's review which inequality has - 12 in its solution set, this way:

A. x + 6 less-than negative 8

-12 + 6 < - 8

-6 < - 8 Not correct

B. x + 4 greater-than-or-equal-to negative 6

- 12 + 4 ≥ - 6

- 8 ≥ - 6 Not correct

C. x minus 3 greater-than negative 10

- 12 - 3 > - 10

- 15 > - 10 Not correct

D. x + 5 less-than-or-equal-to negative 4

- 12 + 5 ≤ - 4

- 7 ≤ - 4 This is correct

The correct answer is D. x + 5≤ - 4

The measure of ABD is (0.18x + 67) degrees and the measure of CBD is (0.07 + 48) degrees. Find the value of X

LUCKY_DIMON [66]

Answer:

See Explanation

Step-by-step explanation:

Given

$ABD = 0.18x +67$

$CBD = 0.07x + 48$

Required

Find x

The question is incomplete as the relationship between ABD and CBD is not stated.

Assume ABD = CBD

The solution is:

$0.18x + 67 = 0.07x + 48$

Collect like terms

$0.18x - 0.07x= - 67 + 48$

$0.11x= -19$

Solve for x

$x = -\frac{19}{0.11}$

$x = -172.72$

Assume ABD and CBD are supplementary

The solution is:

$ABD + CBD=180$

$0.18x + 67 + 0.07x + 48 = 180$

Collect like terms

$0.18x + 0.07x = - 48 - 67 + 180$

$0.25x = 65$

Solve for x

$x = \frac{65}{0.25}$

$x = 260$

Assume ABD and CBD are complementary

The solution is:

$ABD + CBD=90$

$0.18x + 67 + 0.07x + 48 = 90$

Collect like terms

$0.18x + 0.07x = - 48 - 67 + 90$

$0.25x = -25$

Solve for x

$x = \frac{-25}{0.25}$

$x = -100$
