The total number of gallons of paint needed for the big room is 3x and the number of gallons of paint needed for the small room is 2y.
3x + 2y = 16
Given the sizes of the room, the relation should be that,
x = 2y
Solving the equation,
3(2y) + 2y = 16
y = 2
Therefore x is equal to 4 gallons.
With the condition that only the bigger room is painted, the number of gallons of paint used should be 12 gallons and what is left should be 4 gallons.
This is actually really simple algebra. All you need to know is that Y= Mx + B
and M BEING YOUR SLOPE good luck
Answer:
<u>Marcelino will have $7.50: his costs are more than his profits. </u>
Step-by-step explanation:
22.50 + 7.50 + 15.00
In total Marcelino spent $45 to make these balloons.
He wants to sell each balloon for $1.25.
If he sells the 30 balloons he bought for $1.25 he will make:
30 * 1.25 = $37.50... okay he made some money, BUT he spent $45 dollars for the items.
45 - 37.50 = $7.50, Marcelino made no profit... he still needs to make $7.50 to pay off his own costs.
There is a 50% probability.
First add up all of the sections to get a total.
10 Green + 15 Purple + 2 Blue + 3 Red = 30.
There are 15 purple out of 30.
15/30 = 1/2 probability, which is 50%.
