AC = AB + BC
= x + 2 + 7x - 3
= 8x - 1
QR = PR - PQ
= 13y + 25 - (8y + 5)
= 13y + 25 - 8y - 5
= 5y + 20
Answer:
2/25
Step-by-step explanation:
Well if there is 28 feet, that would be (12x28) 336 inches, and 16 inches between the plug and the first light, there would be only 320 inches left for lights. therefore, if there are 4 inches between each light, we divide 320 by 4. the answer we get is 80. there are 80 lights.
Answer:
x = 2/9 (or = 0.222)
Step-by-step explanation:
1/x + 1/(3x) =6 (multiply both sides by 3x)
(1/x) (3x) + [1/(3x)](3x) =6 (3x)
3 + 1 = 18x
4 = 18x
x = 4/18
x = 2/9 (or = 0.222)
54% of the time. 21 and 45 is 66. Two hours is 120. The you subtract
