Hi there! :)
Answer:
B. 0 solutions.
Step-by-step explanation:
Given the equation 7(x + 2) = 7x - 10
Simplify:
7(x + 2) = 7x - 10
Distribute the 7 with the terms inside of the parenthesis:
7x + 14 = 7x - 10
Subtract "7x" and 14 from both sides:
7x - 7x = -10 - 14
0 ≠ - 24. The equation has no solutions.
The answer is B.
In order for this chart to be true, each x and y pair must be proportional to the other ones. (in other words, each row of x and y should increase the same amount as the other ones.)
look at the first row. we can write this as 3/5 (x over y). then look at the third and fourth row. 6/10 = 3/5, and 9/15 = 3/5, so the pairs are proportional.
Answer:
54, 126, 108, 72
Step-by-step explanation:
1. Age 18 and under: 15% of whole circle, 360° * 0.15 = 54°
2. Age 18 - 44: 35%. 0.35 * 360° = 126°.
3. age 45 - 64: 30%. 0.3 * 360°= 108°
4. age 65 and over: 20%. 0.2 * 360° = 72°
