Hanna bought 85 candies and ate 20 of them. How many candies are left?
3x = -212
x = 70.66667
And this is assuming it equals to zero.
Answer:
9:04
Step-by-step explanation:
21 - 17 = 4
it's using subtraction
Answer:
x=0, y=-12
Step-by-step explanation:
you can use substitution to solve for x
-3(x-12)=2x+36
-3x+36=2x+36
subtract 36 from both sides and add 3x to both sides
0=5x
x=0
now plug in 0 as x for either equation
y=0-12
y=-12
to check your work plug in x and y into the other equation
-3(-12)=2(0)+36
36=36
If 32.16 includes the sales tax....then the price before the sales tax will be less then 32.16
that only leaves 2 choices.....
so lets check them...
7% sales tax on 2.25 = 0.07(2.25) = 0.16....so if u spent 2.25 on groceries and added the sales tax of 16 cents....then u would have spent 2.41...thats a long way from 32.16
if u spent 30.06...with 7% sales tax....u would spend 30.06 + 0.07(30.06) = 32.16
so the cost of the groceries before the sales tax is 30.06 <==
