Answer:
A) -7
Step-by-step explanation:
2x + 5y + 30 = 0
Let x = 5/2
Substitute into the equation
2(5/2) +5y +30 =0
5+5y+30=0
Combine like terms
35 +5y =0
Subtract 35 from each side
35-35 +5y = -35
5y=-35
Divide by 5
5y/5=-35/5
y = -7
Answer: x<4
Step-by-step explanation:
Step 1: Simplify both sides of the inequality.

x+3−3<7−3
x<4
Answer:
B, because x does not repeat in that function.
