## Greetings Math Class

Mrs Lynch is redoing the floors in the bedrooms of her house. She has one bedroom that is 9.5 ft by 10.4 ft. She also has 3 bedrooms that are 8.4 ft by 9.35 ft. The amount of flooring is determined by finding the area of all four rooms. Write an equation to show the problem that needs to be solved, use a variable that helps tell the story. Explain your variable. How much flooring does she need?

(9.5 * 10.4) + 3(8.4 * 9.35) = s
s = square feet of flooring

(9.5 * 10.4) + 3(8.4 * 9.35) = s
98.8       +  3   (78.54)    = s
98.8       +      235.62     = s
334.42                  = s
334.42 sq. ft

1. Three houses on my street compete to see who has the longest light that they used to decorate they’re entire house they only use one strand, the griffins lights are 19.87 feet long, the Peterson’s lights are 6.2 times as long, the Browns lights are 3.4 times as much than the Peterson’s. How many feet of lights did the three houses use in total??

The answer is: (19.87 * 6.2) + (123.194 * 3.4) = F F=feet of lights the product is 425.6154 F= 425.6154

2. Emma #1

4. Julia R.
Julia has five gardens. One garden is 6.7 square feet by 4.2 square feet. The other four gardens are 5.6 square feet by 8.3 square feet. Write an equation using a variable, and explain it, to find how many feet in all her gardens are.

(6.7 * 4.2) + 4(5.6 * 8.3) = s
s= square feet of the gardens

(6.7 * 4.2) + 4(5.6 * 8.3) = s
28.14 + 4(46.48) = s
28.14 + 185.92 = s

(4.23 * 5.91) + 3(28.29 * 27.38) = s
s = square feet of the garden

(4.23 * 5.91) + 3(28.29 * 27.38) = s
24.9993 + 2323.7406 = s
2348.7399 =s

14. Reagan needs to redo her carpet. She needs to redo 3 rooms with new carpeting. One room is 13.4 by 8.8. Another room is 9.7 by 5.5. The last room is 11.6 by 6.6. How much new carpeting does she need?
C=total carpeting

(13.4x8.8)+(9.7x5.5)+(11.6x6.67)=C
C=247.56
(13.4x8.8)=117.92
(9.7x5.5)=53.25
(11.6x6.6)=76.56
117.92+53.25+76.56=247.73

15. Dillan needs sod for landscaping. He has one yard 56.7 x 40.4 sq ft., another 36.9 x 25.3 sq ft., third one one is 45.8 x 25.5 sq ft. The amount of sod is determined by finding the area of all three yards. Write an equation to show the problem that needs to be solved, use a variable that helps tell the story. Explain your variable. How much flooring does he need?

(56.7 * \$40.4) + (36.9 * 25.3) + (45.8 * 25.5) = s

2290.68 933.57 1167.9

2290.68 + 933.57 + 1167.9 = 4392.15

4392.15 = s

19. Keshob made four fences, one fence was 9.4 by 3.7, the other fences were 5.4 by 6.3 how much area is in all of the fences use a variable for the the answer. The answer is 136.84

(9.4 x 3.7 = (34.78 = a)

a = area of fence

(5.4 x 6.3 = (34.02 = a)

(34.02 x 3 = (102.06 = a)

102.06 or a is the area of the other three fences

34.78 or a is the area of the first fence

So do 102.06 + 34.78 = a

87.6918 square feet of flooring. - Grace

23. Alec had 1 room that was 9.5 ft. by 10.5 ft. There was 4 other rooms that were 6.4 ft. by 7.8 ft.The walls are being painted for each room. Write an equation to show the problem that needs to be solved, use a variable that helps tell the story. Explain your variable. How much wall space needs to be painted?

(9.5 x 10.5 +4 (6.4 x 7.8) = s
s= square ft. of wall space to be painted
(9.5 x 10.5) + 4 (6.4 x 7.8) = s
99.75 + 4(49.92) = s
99.75 + 199.68 = s
299.43 = s
299.43 = sq. ft. of wall space to be painted

24. Vincent has 179 marbles and wants to split them evenly into 8 boxes. About how many marbles will be in each box? You can round 179 to 170 and 8 to 10. The real answer would be 179 divided by 8 = 22 R3.
It is a remainder 3 because 3 of the left over marbles are not needed.
