Answer:
is 30 hope I helped!!:D
Step-by-step explanation:
step 1 : cross multiply.
10/3= k/9
(10)*(9)=k*(3)
90=3k
step 2: flip the equation.
3k =90
step 3: Divide both sides by 3.
3k/3=90/3
k=30
Answer:
4 times
Step-by-step explanation:
1 quart is equivalent to 32 fluid ounces.
If each eruption consumes 8 fluid ounces of vinegar. Assuming that the amount of vinegar required per eruption is constant, the number of times Tanvi can make her volcano erupt is:
Tanvi can make her volcano erupt 4 times with 1 quart of vinegar.
To get your answer you'd do 122.80/5
And that equals 24.56
So your answer would be A.
Hope this helps :)
P+ p(.08)= 51.84
p is the original price of the item
if you take 51.84 which is the total amount after taxes are added and divide it
by 1+tax you will get the original price
so if p + p(.08)=51.84 then 51.84/1.08= p
p =48
48+ 48(.08)=51.84
