How do i solve this.

Let us set up some variables:

L: Length
W: Width

Now let us set up some equations based on the facts:

length of rectangle is 4 times its width --> L = 4W
perimeter of rectangle is 80 --> 2L + 2W = 80

Equations:

L = 4W -- equation 1

2L + 2W = 80 -- equation 2

Plug the value of L from equation 1 into equation 2

2(4W) + 2W = 80

8W + 2W = 80

10W = 80

W = 8 -- equation 3

Plug the value of W from equation 3 into equation 1:

L = 4W = 4 * 8 = 32

Therefore the length is 32 and the width is 8.

Hope that helps!

Mr. Martin's math test, which is worth 100 points, has 35

AlekseyPX

Number of questions worth 5 points = 10

Number of questions worth 2 points = 25

Further explanation:

The given system is a system of linear equations in two variables.

We will use the subsitution method to solve the system

Given equations are:

$x+y=35\\5x+2y=100$

From equation no 1:

$x+y=35\\x=35-y$

Putting x=35-y in second equation

$5x+2y=100\\5(35-y)+2y=100\\175-5y+2y=100\\-3y=100-175\\-3y=-75\\\frac{-3y}{-3}=\frac{-75}{-3}\\y=25\\Putting y=25 in first equation\\x+25=35\\x= 35-25\\x=10$

Hence,

Number of questions worth 5 points = 10

Number of questions worth 2 points = 25

Shawna and her best friend Keisha go shopping. The function p(t) = 3x +2x-4x2+ 21 represents how much money each girl spent base

NNADVOKAT [17]

Answer:

$\$30$

Step-by-step explanation:

we have

$p(t)=3x+2x-4x^{2}+21$

<em>Find the amount of money that each girl spent</em>

For t= 2 hours

$p(2)=3(2)+2(2)-4(2)^{2}+21$

$p(2)=10-16+21$

$p(2)=\$15$

<em>Find the amount of money that they spend together</em>

Multiply by 2 the amount of money that each girl spent

$(2)\$15=\$30$
