Answer:
10.4 hope this help ;) 77 x 10.4
Step-by-step explanation
turn the 10.4 into .10 then multiply like this
77 x .10 =7.7
77+ 7.7 = 84.7
Answer:
Every class period is 43 minutes long.
Equation:
(m - 10) ÷ 4
Answer:
7, 11, 14 feet from shortest to longest
Step-by-step explanation:
Let's say that the shortest pipe is equal to x, and work from there.
The medium size piece is 4 feet longer than the shortest piece, so it is equal to 4+x
The longest piece is twice as long as the shortest piece, so it is equal to 2 * x.
The three pieces added up make up the 32 feet pipe, so we can write this as
(2*x) + (4+x) + x = 32
2*x + 4 + x + x = 32
4 * x + 4 = 32
subtract 4 from both sides to isolate the x and its coefficient
4 * x = 28
divide both sides by 4 to isolate the x
x= 7
Therefore, the shortest piece is x=7 feet long. The medium piece is x+4=11 feet long, and the longest piece is x*2=14 feet long
Answer:
x < -7
Step-by-step explanation:
54 = 3x + 37.5 <== ur equation....and x = number of years
54 - 37.5 = 3x
16.5 = 3x
16.5 / 3 = x
5.5 = x......so it would take 5.5 years...or 5 1/2 years <=
