<u>Final Answer:</u>

\frac{64}{3}

<u>Step-by-step explanation:</u>

20 ÷ \frac{15}{16}

\frac{20}{1} ÷ \frac{15}{16}

(reciprocal method):

\frac{20}{1} ÷ \frac{16}{15}

(change the operation to multiplication)

\frac{20}{1} × \frac{16}{15} = \frac{320}{15\\}       (multiply, then reduce)

64/3 ⇒ 64/3

This partial circle has a radius of 11 inches.
Alecsey [184]
First, find the area of the circle
 pie*radius to the power of 2(radius*raduis)
(11*11=121) 121*3.14=379.94
take your answer and divide it by 4 we would divide it by 2 if we had a semicircle but since we have a 3/4 circle we divide by 4 and then times the Quotient by 3
379.94/4=94.985
94.985*3=284.955
Round ur answer to the nearest tenth so it equals 284.96

What is the x-value of the solution to the system of equations?
ValentinkaMS [17]

Answer:

The solution to the system of equations is:

x=4,\:y=-3

Step-by-step explanation:

Given the system of equations

5x + 4y =8

2x- 3y = 17

solving the system of equations

\begin{bmatrix}5x+4y=8\\ 2x-3y=17\end{bmatrix}

\mathrm{Multiply\:}5x+4y=8\mathrm{\:by\:}2\:\mathrm{:}\:\quad \:10x+8y=16

\mathrm{Multiply\:}2x-3y=17\mathrm{\:by\:}5\:\mathrm{:}\:\quad \:10x-15y=85

\begin{bmatrix}10x+8y=16\\ 10x-15y=85\end{bmatrix}

10x-15y=85

-

\underline{10x+8y=16}

-23y=69

\begin{bmatrix}10x+8y=16\\ -23y=69\end{bmatrix}

solve for y

-23y=69

Divide both sides by -23

\frac{-23y}{-23}=\frac{69}{-23}

y=-3

\mathrm{For\:}10x+8y=16\mathrm{\:plug\:in\:}y=-3

10x+8\left(-3\right)=16

10x-24=16

10x=40

Divide both sides by 10

\frac{10x}{10}=\frac{40}{10}

x=4

Thus, the solution to the system of equations is:

x=4,\:y=-3
