4x+5≤−4x
Please I have been trying to do 1 step inequalities for hours

I'll keep calculating for this problem. but hope this can help you. but I'll keep calculating havea good day.

Step-by-step explanation:

4x + 5 ≤ - 4x

4x + 4x ≤ - 5

8x ≤ - 5

x ≤ -

x ∈ ( - ∞ , - 0.625 ]

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

we can't see all full 4 options, but if this is the full option, than the very left one is correct:

-2/5 * -3 3/4

remake the question, adding a picture of all the question, or write down the full left and right answers.
