Answer:
3(5x+8)
Step-by-step explanation:
Step-by-step explanation:
(4z +9) + ( 9y - 2) =180
4z + 9y = 173 ....... Equation 1
The angles of triangle = 180
We miss one angle and in opposite of that angle is 135 so
( 5y +5 +4z +9)+135 = 180
5y + 4z + 149 = 180
5y + 4z = 31 ....... Equation 2
Subtract between two equations 1 & 2
4y = 142
y = 142/4
y = 35.5
Answer:
B, 5/4s
Step-by-step explanation:
If something increases by 1/4, it means that it is the original number + 1/4 of it.
Ex: x + 1/4x = 5/4x
So if we substitute s for x, the answer must be 5/4s, or B
