Answer:
17
Step-by-step explanation:
The two base angles are congruent, so we have ...
x +17 = 4x -34
51 = 3x . . . . . . . add 34-x
17 = x . . . . . . . . .divide by 3
1 x 19 = 19
2 x 9.5 = 19
4 x 4.75 = 19
7x + 3y = 30
-2x + 3y = 3....multiply by -1
-----------------
7x + 3y = 30
2x- 3y = -3 (result of multiplying by -1)
----------------add
9x = 27
x = 27/9
x = 3
7x + 3y = 30
7(3) + 3y = 30
21 + 3y = 30
3y = 30 - 21
3y = 9
y = 9/3
y = 3
solution is (3,3)
0.36 is the answer. brainliest?
