Answer:
-2/9
Step-by-step explanation:
first you are going to distrubute 2/5, so 2/5 times x is 2/5x and 2/5 times -2 is -4/5
next you set up the problem with those two answers which gives you:
2/5x - 4/5 = 4x
then multiply both sides of the equation by 5: 2x-4=20x
next move the constant to the right side and chnage the sign: 2x=20x+4
then combine like terms: -18x=4
after that divide both sides of the equation by -18: -2/9
so x= -2/9
The answer is A
B and D are not answer as they show50-x=50
so x have to be 15 or 5 in A and C
but in C x=5 but 2×x+50 is nt equal to 70
so it is A
Answer:
Line DG is equal to 16
Step-by-step explanation:
We know that
In a parallelogram, opposite sides are congruent.
Line DG is congruent to line FE, so they must have sides of equal length.
4z-48=z
4z=z+48
3z=48
48/3=z
16=z
Now we know that the variable is 16 increments, so we sub the 16 in for z in line DG
4(16)-48
64-48=16
Line DG is equal to 16
I believe its c, sorry if im wrong.
