Flora made 3 withdrawals of $65 each from her bank account. What was the overall change in her account?
Inessa05 [86]

Answer:

-$195

Step-by-step explanation:

If she made 3 withdrawals and they are all the same amount then the equation is

65 x 3 or 65+65+65

Which equals 195

Since she is taking money out of her bank account, the total change is negative because she is subtracting it from her current amount

The total change is -$195

I need help to find the measures and equation pls.
siniylev [52]

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
