Answer:
Step-by-step explanation:
11.-3(2x-8)=-12
-6x+24=-12
-6x=-12-24
x=-36/-6
x=6
12.4(6+2x)=0
24+8x=0
8x=0-24
x=-24/8
x=-3
13.3x+2x+6=-15
5x+6=-15
5x=-15-6
x=-21/5
14.4=-2(x+3)
4=-2x-6
4+6=-2x
10/-2=x
-5=x
15.27=46+2x-x
27=46+x
27-46=x
-19=x
Answer:
D.
Step-by-step explanation:
in order to choose the correct answer, it is enough to substitute the given coordinates [(-3;-1) and (-6;8)] into the equations:
A. -1-8=3(-3+6); ⇔ -9≠9; wrong
B. -1+8=-3(-3+6); ⇔ 7≠-9; wrong
C. -1+8=3(-3-6); ⇔ 7≠-27; wrong
D. (-3;-1): -1-8=-3(-3+6); ⇔ -9=-9
(-6;8): 8-8=-3(-6+6); ⇔ 0=0 - correct.
Note, the suggested way is not the only one.
PS. the given points are (-3;-1) and (<u>-6;</u>8).
Answer:
9/10
Step-by-step explanation:
to do this you would want to find a common denominator. then to divide fractions you would want to apply the keep change flip rule. keep the first fraction. change the division sign to multiplication and flip the fraction. then proceed to multiple. then you have your answer.
