I've Got Your Back:
What do you need help with?
Here's what you wanna do.
Add 6 dollars to 12.75.
You now have $18.75
Now subtract 10
18.75 - 10 = 8.75
Now subtract 3.50
8.75 - 3.50 = 5.25
So, the cotton candy costs $5.25
Answer:
√7x−49√x
Explanation:
First of all, expand by multiplying √7x⋅√x and √7x⋅7√7respectively:
√7x(√x−7√7)=√7x⋅√x−√7x⋅7√7
... you can express √7x as √7⋅√x...
=√7⋅√x⋅√x−√7⋅√x⋅7⋅√7
=√7⋅(√x)2−(√7)2⋅√x⋅7
... the operations squaring and taking the square root "eliminate each other"...
=√7⋅x−7⋅√x⋅7
=√7x−49√x

Answer:
24x^9*z^5
Step-by-step explanation:
combine coefficients and add exponents for like terms
hope this helps you :)
Let x be the number of cases of paper towels and y be the number of cases of soap. The system of linear equation that would best represent the given is,
x + y = 10
12x + 15y = 129
The values of x and y are 7 and 3.
Sarah both 7 cases of paper towel.
It is not possible for Sarah to buy exactly 20 bottles because first of all the cases contains only 12 bottles and 20 is not divisible by 12.
