Answer:
76
Step-by-step explanation:
if w=45, you'd get 2(45-7) by replacing the variable (w) with its value (45)
so first you'd distribute 2 to the 45 and the 7
now it'd be:
90-14=76
so the answer would be 76! :)
It is only 1 proportion, and it is 1 problem.
10 8
---- = ---
X 4
1). It is 8x=40
2). Divide both sides
by 8
3). X=5
Multiply the left and right side by 7 to get rid of the denominator, leaving you with 6x=-84. Then divide, x=-84/6, x=-14!
Answer:
Step-by-step explanation:
Let "n" be the second odd number in the sequence
(n - 2) + n + (n + 2) + (n + 4) + (n + 6) = 135
5n + 10 = 135
5n = 125
n = 25
23 + 25 + 27 + 29 + 31 = 135
