Answer:
x2 = 60
Step-by-step explanation:
If the variables x and y are inversely proportional, the product x * y is a constant.
So using x1 and y1 we can find the value of this constant:
Now, we can use the same constant to find x2:
So the value of x2 is 60.
Answer:
(x + 3b)(3 + 5a)
Step-by-step explanation:
Assuming you require the expression factorised.
Given
3x + 9b + 5ax + 15ab ( factor the first/second and third/fourth terms )
= 3(x + 3b) + 5a(x + 3b) ← factor out (x + 3b) from each term
= (x + 3b)(3 + 5a) ← in factored form
Answer:
Seven one dollar bills and eight five dollar bills.
Step-by-step explanation:
8 + 7 = 15 bills
8 x 5 = $40
7 x 1 = $7
