Tina is cutting construction paper into rectangles for a project. She needs to cut one rectangle that is 15 inches × 12 1/3 inches. She needs to cut another rectangle that is 10 1/4 inches by 10 1/3 inches. How many total square inches of construction paper does Tina need for her project?

Answers

Answer:

Step-by-step explanation:

Remark

This is an "in theory" type of question. She's going to actually need a little more.

Area 1

L = 15

W = 12 1/3

Area = L*W

Area = 15 * 12 1/3                    I wonder if you know what the distributive property is. I'll try it. If you don't understand, leave a remark

Area = 15 * (12 + 1/3)              Multiply both parts by 15

Area = 15*12 + 1/3 * 15

Area = 180 + 5

Area =                                                                          185 square inches.

Area 2.

This is a little harder because their are

2 fractions.

The easy way to do this is change to decimals

L = 10 1/3 = 10.33333333

W = 10 1/4 = 10.25

Area = 10.3333333 * 10.25

Area =                                                                       105.92      Add

Total Area

The total area =                                                        290.92

Solve this system of equations by using the elimination method -2x-2y=-6, 3x+4y=8

Answers

Step-by-step explanation:

- 2x-2y=-6

3x+4y=8

multiply equation (1) by 3 and equation (2) by 2

- 6x-6y=18

6x+8y=16

Add

2y=34

y= 34÷2

y=17

substitute 17 for y in equation (2)

3x+4y=8

3x+4(17)=8

3x+68=8

3x=8-68

3x=-60

x=-60÷3

x=-20

x=-20,y=17
