Answer: -11
Step-by-step explanation:
n+n+1+n+2=-33
n+n+n+1+2=-33
3n=-33-1-2
3n=-36
n=-12
n+1= ==> middle integer
-12+1=-11
Answer:
64.8 in
Step-by-step explanation:
The pipe is 324 in and you cut in in two. Since we know that one piece is five times the length of the other, we can make the equation 324=5x. Divide both sides by five gets us 64.8 = x.
To check our work, let's multiply 64.8 by 5. It does equal 324 so we are correct.
Answer:
smaller number = 3 5/24
larger number = 6 13/24
Step-by-step explanation:
let the larger number = x
smaller number = y
x - y = 3 1/3 equation 1
2(x +y) = 191/2 equation 2
divide equation 2 through by 2
x + y = 9 3/4 equation 3
subtract equation 1 from 3
2y = 6 5/12
y = 77/12 x 1/2 = 3 5/24
substitute for y in equation 1
x - 3 5/24 = 31/3
x = 3 1/3 + 3 5/24
x = 6 13/24
Answer:
the answer should be A) 12
Step-by-step explanation:
54 ÷ 3^2 × 2
54 ÷ (3 × 3) × 2
54 ÷ 9 × 2
6 × 2
12
2x-1=7x+44 is equal to -9. The first step is to add one on both sides to get x by itself. Right now you should have 2x= 7x+45. Then you subtract 7x from both sides. You should have -5x=45. Now divided -5 on both sides. You should get the answer x=-9. By the way remember only subtract variables from other variable and regular numbers only from other regular numbers.
