Answer:
117, 118
Step-by-step explanation:
if 2 consecutive numbers have a sum of 235, then
Let the 2 numbers be n and n+1
Given That:
n + n+1 = 235
Simplify and solve:
2n + 1 - 235
2n = 234
n = 117.
If n = 117, then n +1 = 118. These are the 2 consecutive numbers.
Hope this helps.
Good Luck
Solve for x of first equation,
17-3=8x
14=8x
7/4 = x
x= 7/4
Put the x value in 4x+9,
4x+9 = 4(7/4) + 9 = 7+9 =16
Therefore, the value of 4x+9 is 16.
