A rectangular rug has a perimeter of 220 feet. The width of the rug is two feet less than the length. Find the length and the wi
Gekata [30.6K]

Answer:

The length is 56 and the width is 54.

Step-by-step explanation:

The perimeter of a rectangle is 2x+2y (width and length on both sides). so 2x+2y=220. Also x=y-2, because the width is 2 feet less than the length. Fill x=y-2 in 2x+2y=220 and we get 2(y-2)+2y=220. 2y-4+2y=220. 4y=216. y=54. Fill in y=54 in 2x+2y=220 and we get 2x+2(54)=220. 2x=220-2(54)=112. x=56.

Find "C" when "F" = 120.<br>Round to tenths.<br> C= 5F-160 /9​
GenaCL600 [577]

Answer:

C = 48.9

Step-by-step explanation:

C= 5F-160 /9

C= (5F -160)/ 9

Put F =120

C = (5(120) - 160)/9

C= (600 - 160)/9

C = 440/9

C = 48.89≈ 48.9

Triangle sum theorem
sleet_krkn [62]

Answer:

e= 60

Step-by-step explanation:

we know that triangles add up to 180

so 35+24+2e+1= 180

simplify: 60+2e= 180

subtract 60 on both sides: 2e= 120

divide both sides by 2: e=60
