"Product" is the result of the multiplication.
So, product of two and x means we will multiply 2 by x
product = 2x
"Quotient" is the result of the division.
So, quotient of 15 and 2x means we will divide 15 by 2x
The expression is: 15/2x
Answer:
C. Infinite solutions
Step-by-step explanation:
I'll use the equal value method and make the second equation equal 6 instead of 18, so I have to divide the entire equation by 3
(6x+15y=18)/3 = 2x +5y = 6
The second equation is the same thing as the first one, meaning no matter what value they will equal the same thing, also meaning there are infinite solutions
Answer:
88
Step-by-step explanation:
87+93+86+90+84=440
440÷5=88
Have a good day ^^
Answer: -1 and 1
Step-by-step explanation:
i gotchu, no worries!
first, move the constant to the right. then, you calculate that. then change the signs, and simplify the expression. (i can't type out square root signs, so thats why there's no work shown.)
then, evaluate it.
x^2 - 9 = -2^3
next, move the constant to the right.
x^2 - 9 = -8
next, calculate it.
x^2 = -8 + 9
simplify it.
x^2 = 1
finally separate the solutions.
x = 1
x = -1
Answer:
120$
Step-by-step explanation:
Equation
$= 10x + 50
x is the amount of hours.
Plug in for x
$ = 10(7) + 50
$ = 70 + 50
$ = 120
