44 - 1 + 7q = 106
43 + 7q = 106
7q = 63
q = 9
Answer:
probably 2/4 try it I don't know
Answer: 550
Step-by-step explanation:
Use proportion:
22:1=x:25
25*22=1x
x=550
159 seconds. The 1st two slices of bread will take 60 seconds to toast. 20 second to put in and out. And 6 seconds to turn them over. The 3rd piece will take 60 seconds to toast, 10 seconds to put in and out, and 3 seconds to turn over. 86 seconds + 73 seconds= 159
A = L * W
A = 70
70 = L * W
P = 2(L + W)
P = 34
34 = 2(L + W)
34/2 = L + W
17 = L + W
17 - W = L
70 = L * W
L = 17 - W
70 = W(17 - W)
70 = -W^2 + 17W
W^2 - 17W + 70 = 0
(W - 10)(W - 7) = 0
W - 10 = 0 L = 17 - 10
W = 10 L = 7
W - 7 = 0 L = 17 - 7
W = 7 L = 10
so either the width is 10 meters and the length is 7 meters OR the width is 7 meters and the length is 10 meters
