The perimeter of a basket ball court is 108 m and the length is 6 m long than twice the width. What are the length and the width

Gnoma [55]

Let's say

P = perimeter, L : Length and w : width

Then

$P=2(L+w)=2L+2w=108$

But

$L=6+2w$

So

$2L+2w=108\\2(6+2w)+2w=108\\12+4w+2w=108\\12+6w=108\\6w=108-12\\6w=96\\w=16$

$L=6+2w\\L=6+2(16)\\L=6+32\\L=38$

We verify :

$2L+2w=108\\2(38)+2(16)=108\\76+32=108\\108=108$

Length = L = 38
Width = w = 16

What ordered pair is a solution of the equation y-3=5(x-2)

RideAnS [48]

Answer:

(0,-7)

Step-by-step explanation:

In this question, we need to find an ordered pair of (x,y)

First we need to solve the equation for Y. It will be:

y-3=5(x-2)

y=5x-10 +3

y= 5x -7

Then, using the equation you can find the value of y using the value of x. If x= 0 the calculation will be

y= 5x-7

y= 5(0) - 7

y=-7

The ordered pair will be: (0,-7)

In the diagram, the measure of angle 8 is 124°, and the measure of angle 2 is 84°.

Margaret [11]

m∠8 + m∠7 = 180°

therefore

m∠7 = 180° - m∠8

m∠8 = 124°

substitute:

m∠7 = 180° - 124° = 56°

Answer: 56 degrees

Evaluate: 5–^2 = <br> WILL MARK AS BRAINLIEST

Elanso [62]

When you have a negative exponent, you move it to the other side of the fraction to make the exponent positive.

For example:

$x^{-2}$ or $\frac{x^{-2}}{1}=\frac{1}{x^2}$

$\frac{1}{y^{-2}}=\frac{y^2}{1}$ or y²

So:

$5^{-2}=\frac{1}{5^2}=\frac{1}{25}$

Your answer is B
