Answer:
x = 12
Step-by-step explanation:
Solve for x:
(3 x)/4 = 9
Multiply both sides of (3 x)/4 = 9 by 4/3:
(4×3 x)/(3×4) = 4/3×9
4/3×3/4 = (4×3)/(3×4):
(4×3)/(3×4) x = 4/3×9
4/3×9 = (4×9)/3:
(4×3 x)/(3×4) = (4×9)/3
(4×3 x)/(3×4) = (3×4)/(3×4)×x = x:
x = (4×9)/3
9/3 = (3×3)/3 = 3:
x = 4×3
4×3 = 12:
Answer: x = 12
1/4 to 1/2 percentage of change is 1/2
6) 3x + 4 < - 62 x = - 23 ⇒ 3(-23) + 4 < - 62
<u> - 4 - 4 </u> -69 + 4 < - 62
3x < -66 - 65 < - 62
<u>÷ 3 ÷3</u>
x < -22
7) x/-5 + 1 <u><</u> 7 x = -30 ⇒ -30/-5 + 1 <u><</u> 7
<u> - 1 -1</u> 6 + 1 <u><</u> 7
x/-5 <u><</u> 6 7 <u><</u> 7
<u> × -5 × -5</u>
x <u><</u> -30
8) x/3 - 2 <u>></u> -12 x = -30 ⇒ -30/3 - 2 <u>></u> -12
x/3 <u>></u> -10 -10 - 2 <u>></u> -12
<u>* 3 *3</u> -12 <u>></u> -12
x <u></u><u>></u> -30
9) -2x - 6 > -18 x = 5 ⇒ -2(5) - 6 > -18
<u> +6 +6</u> -10 - 6 > -18
-2x > -12 -16 > -18
<u>÷ -2 ÷ -2</u>
x > 6 ⇒ x < 6
*flip the inequality sign because the divisor is a negative number: This is to make the inequality true.
