Answer:
x = 20
Step-by-step explanation:
Since one part of the straight angle = 90°, then
4x - 10 + x = 90, that is
5x - 10 = 90 ( add 10 to both sides )
5x = 100 ( divide both sides by 5 )
x = 20
10 20 30 40 50 60
Step-by-step explanation:
Answer: 7 gallons decrease per minute
Step-by-step explanation:
56 gallons / 8 minutes = 7 gallons per minute
to make sure do it backwards: 7 gallons x 8 minutes = 56 gallons :)
The formula to start with is (DC +CE) * CE = (AB + BE) * BE
Replace the letters with the numbers and equations:
(1 + x+4) * x+4 = (11 + x+1) * x+1
(x+5) * (x+4) = (x+12) * (x+1)
x^2 + 9x +20 = x^2 +13x +12
x^2 = x*x = 2x
11x+20 = 15x+12
20 = 4x+12
8 = 4x
x = 8/4
x = 2
