Answer:

Step-by-step explanation:

Find the diagram attached

If W and X are the endpoints of a diameter on the circle, this means that arc WX is 180degres

Since the angle at the vertex is half the angle at the intercepted arcs.

<V = 1/2(arcWX)

4x+18 = 1/2*180

4x+18 = 90

4x = 90-18

4x = 72

x = 72/4

x = 18

Hence the value of x is 18

8+—3(6+—6a) help please

LenKa [72]

We know that:

$(+)+(-)=(-)$

and:

$(-)*(+)=(-)$

$8+(-3)[6+(-6a)]=8+(-3)*6+(-3)*(-6a)=8-18+18a$ $=(-10)+18a$

if you have solve for $a$ then:

$(-10)+18a=0$
$18a=10$
$a= \frac{10}{18}$
$a=\frac{5}{9}$

What is the savings rate per month?

dedylja [7]

Answer:

My guess is $29

Step-by-step explanation:

So first I take the difference of the 10th and 6th month, which is 116.

I take that and divide it by 4, because that was the change in 4 months(10-6)

116÷4=29
