Perimeter:13

Step-by-step explanation:

equation: 2x + 5 =2x +8

 2x + 5= 2x+ 8              

 4x + 5= 8

   4X= 13

x= 0.3

value of X: 0.3

for m(x)=-2x+7, find the value of x for which m(x)=13

Answers

Answer:

x = -3

Step-by-step explanation:

m(x) = -2x + 7

13  = -2x + 7

6 = -2x

x = -3

The answer is x= -3




The explanation if you need it is since m(x)=13 we get the equation 13=-2x+7. Then we use the equation to find x.


13= -2x+7
-7 -7
6= -2x
— —
-2 -2

-3=x

You then want to check your answer by substituting -3 for x

13= -2(-3) +7
13= 6+7
13=13

The math department needs to buy new textbooks and laptops for the computer science classroom. The textbooks cost $116.00 each, and the laptops cost $439.00 each. If the math department has $6,500 to spend and purchases 30 textbooks, how many laptops can they buy

Answers

Answer:

6 laptops

Step-by-step explanation:

First, find the amount spent on the textbooks:

30(116)

= 3480

Subtract this from the total amount they have to spend:

6500 - 3480

= 3020

Divide this amount by 439 to find how many laptops they can buy:

3020/439

= 6.8

Round down to 6 since you can only have full laptops:

= 6

So, they can buy 6 laptops

Abargain clothing store is selling 5 shirts for $20.
Louis said, "I can buy 2 shirts for $8."
William said, "I can buy 1 shirt for $4."
Which statement is TRUE?
A
Only Louis's statement is true.
B
Only William's statement is true.
Both Louis and William's statements are true
D
Neither Louis nor William's statements are true.

Answers

Answer: Both of their statements are true. Explanation: If you can buy 5 shirts for $20, that means the unit price would be $4 per shirt. (to find the unit price just divide the cost by the quantity) So, it is true that you can buy one shirt for $4 and 2 shirts for $8. Hopefully this helps.
