Answer:
4(2a+5)
Step-by-step explanation:
4 times 2a= 8a
4 times 5= 20
Answer:
2
Step-by-step explanation:
It's just a multiplication problem, 8 x 1/4 is 8/4, which is equal to 2.
John’s father will pay $300.
If you divide $500 into 5 equal parts, each part will be comprised of $100. In other words, 1/5 of $500 is $100. This is proven because $100 • 5 = $500.
But since you are trying to find 3/5 of $500, (not 1/5, which is what we just found). This means we must find the total value of 3 of the five equal parts. To do this, multiply
$100 • 3, since $100 is 1/5 of $500.
$100 • 3=$300, so the answer is B. Johns father will pay $300.
Answer:
1, 3, 5 or 1, 2, 3 I think? Sorry if its not
You use a system of equations to solve this.
x will be one integer and y will be the other.
2y - 7 = x
x^2 + y^2 = 433
You can plug (2y - 7) in for x in the second equation.
(2y - 7)^2 + y^2 = 433
4y^2 - 28y + 49 + y^2 = 433
5y^2 - 28y -384 = 0
y = 12 or -32/5
It has to be 12 since -32/5 is not an integer.
Plug 12 in for y to get x.
2(12) - 7 = x
x = 17
The integers are 12 and 17.
