Answer:
a=7, b=14
Step-by-step explanation:
a. 2/6=x/21
cross multiply=
2×21=x×6
then solve
42=6x
divide both sides by 6
x=42/6=<u>7</u>
b. 150/84=25/x
cross multiply=
84×25=150×x
then solve
2100=150x
divide both sides by 150
x=2100/150=<u>1</u><u>4</u>

Answer:
D) no solution.
Step-by-step explanation:
4(x + 1) ≤ 4x + 3
First, distribute 4 to all terms within the parenthesis:
4(x + 1) = 4(x) + 4(1) = 4x + 4
4x + 4 ≤ 4x + 3
Isolate the variable, x. Treat the "≤" as an equal sign, what you do to one side, you do to the other. Subtract 4x and 4 from both sides:
4x (-4x) + 4 (-4) ≤ 4x (-4x) + 3 (-4)
4x - 4x ≤ 3 - 4
0 ≤ -1
Since x was eliminated from the inequality, and you need the x for the inequality, your answer is D) no solution.
