Answer:
Step-by-step explanation:
9/16=x/12
cross product
16x=9*12
16x=108
x=108/16
simplify
x=27/4
---------------
x-3/18=12/9
x=12/9+3/18
x=24/18+3/18
x=27/18
x=3/2
--------------------
7/11=18/x+1
18/x=7/11-1
18/x=7/11-11/11
18/x=-4/11
x=18/(-4/11)=(18/1)(-11/4)=-198/4=-99/2
x=-99/2
More info please... how many minutes can they both use altogether?
Answer:
The unit rate at HEB is $0.23 per ounce. The unit rate at Fiesta is $0.25 per ounce. So HEB has the better buy for dish soap.
Step-by-step explanation:
To calculate unit rate, you divide the price by the oz.
So for HEB, you should do $2.80/12 oz. This will equal to $0.23 per ounce. For Fiesta, you should do $2.00/8 oz. This will equal to $0.25 per ounce.
To determine which one is the better buy, the lower priced one is better, meaning HEB is the better buy.
Answer:
32
Step-by-step explanation:
Evaluate g(4), then substitute the value obtained into f(x) , that is
g(4) = 4² - 6 = 16 - 6 = 10, then
f(10) = 3(10) + 2 = 30 + 2 = 32
