Answer:
-7 m + 8 n + 5
Step-by-step explanation:
-4m + 5n - 2 - 3m + 3n + 7
combine like terms
-4m -3m +5n +3n -2+7
-7 m + 8 n + 5
-2x-3=8
-2x=8+3
-2x=11
x=-11/2
-2x+4=22
-2x=22-4
-2x=18
x=-9
Answer:
values of x and y is (4, -2), (0, 0) and (2, 10)
Step-by-step explanation:
Answer:
Equation: 7x + 8x = 180
x = 12
∠CBA = 84
∠CFH = 96
Step-by-step explanation:
We can see that ∠CBA = ∠CFE and ∠CBD = ∠CFH.
We know that the sums of two angles on a straight line are going to be equal to 180.
∠CBA = 7x
∠CFH = 8x
To find the value of x, we must do the following:
7x + 8x = 180
15x = 180
15x/15 = 180/15
x = 12
Now we just substitute to find the angle measures:
∠CBA = 7 · 12 = 84
∠ CFH = 8 · 12 = 96
