Answer:
9
Step-by-step explanation:
the answer is 9 because 7=y so , 7+2=9
2/3x = 6
Multiply both sides by 3x
2 = 6.3x
2 = 18x
x = 2/18
x = 1/9
Answer:
Step-by-step explanation:
the answer is D. 6 ≤ x < ∞
Consider this option:
1. formula of perimeter is: P=2(a+b), where a & b - the sides of rectangle.
2. according to the condition 2(x+(x+4))<120; ⇒ x<28
answer: D. x<28
30+6+0.4+0.09+0.005=36.495
