Each grandchild receives x.
Each child receives 2 times as much as a grandchild, so each child receives 2x.
The wife receives 5 times as much as a child, so the wife receives 5 * 2x = 10x.
There is 1 wife: 10x
There are 2 children: 2 * 2x = 4x
There are 3 grandchildren: 3x
Total: 10x + 4x + 3x = 17x
17x = 510,000
x = 30,000
Answer:
Each grandchild gets $30,000.
Each child gets 2 * $30,000 = $60,000.
The wife gets 10 * $30,000 = $300,000.
Answer:
"The Quadratic Equation, Formula, & Discriminant. If ax² + bx + c = 0 then x = . The first equation is called the general form of a quadratic equation. The second equation is called the Quadratic Formula because it states the solution -- provides a formula for computing the simplified answer(s) by using the values of the first equation."
Answer:
B)
and C) 
Step-by-step explanation:
Once a linear function has a constant rate of change, you just have to find the linear functions. Also, the other ones are quadratic functions, and their graph are parabolas, which don't have a constant rate of change.
Considering 
has a constant positive rate of slope 2.
has a constant negative rate of slope -7
Answer:
Step-by-step explanation:
<u />
13 × 9w = 13 × 
117w = 5w - 6 + 13
117w = 5w + 7
117w - 5w = 5w - 5w + 7
112w = 7
112w ÷ 112 = 7 ÷ 112
Basic Pay = $40
Commission for 1 pair of shoes = $4.50
Let x be the number of shoes he needs to sell.
40 + 4.5x ≥ 112
4.5x ≥ 72
x ≥ 16
Answer: He must sell at least 16 pairs of shoes.
