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.
The formula of a slope:
We have the points (-4, -3) and (-3, s) and the slope m = 3. Substitute:
Answer:
The specific gravity of kerosene is 0.82
Step-by-step explanation:
Let
x -----> the weight in grams of a cubic centimeter of Kerosene
y ----> the weight in grams of a cubic centimeter of water
z ---> the specific gravity of a substance
so
we have
substitute the values
400-126=274
400
126
-----
0-6 can't go into so make the 0 a 6
Then make 0-2 make 0 a 10 then a 9
Then make 4 into a 3
Only answer that can give u zero is zero
