AD + DG = AG.
If DG is twice as long as AD, then DG is 20.
Add DG and AD together and you can find that AG is 30.
Answer:
x=3, y=22. (3, 22).
Step-by-step explanation:
-5x+3y=51
y=10x-8
----------------
-5x+3(10x-8)=51
-5x+30x-24=51
25x-24=51
25x=51+24
25x=75
x=75/25
x=3
y=10(3)-8
y=30-8
y=22
Answer:
There are 2 solutions: x = -5, 9.
Step-by-step explanation:
(x-2)^2 =49
Take square roots of both sides:
x - 2 = +/- 7
So x - 2 = 7 gives x = 9 , and
x - 2 = -7 gives x = -5.
