Theres an app called photomath thats useful for these kinds of problems
18 plus 12 divided by 2 = thats how u get the answer
38).
a).
Will(March) = 3
Hector(March) = 5
Lydia(March) = x
Will(March) + Lydia(March) = 3 + x
Will(April) = 3 + x or x + 3 .
b).
2 less than Hector()March) = 3
Hector(April) = 3 + Lydia(March)
Hector(April) = 3 + x or x + 3 .
c).
Yes, by Golly ! Will and Hector both volunteered
the same number of hours in April.
We translated the statements in (a) and (b) into algebraic expressions,
and we found that they're both the same expression.

= g + 6 inches.
Answer:
135 = 3y + 3r
y = 30; r = 15
Step-by-step explanation:
y = 3y + 3r
Where,
y = total number of flowers in the garden = 135
y = number of flowers in each yellow flower bed = 30
r = number of flowers in each red flower bed
135 = 3(30) + 3r
135 = 90 + 3r
135 - 90 = 3r
45 = 3r
r = 45/3
r = 15 flowers
number of flowers in each red flower bed = 15
