Answer:
She used 5.775 pints of white paint to paint her bedroom walls.
Step-by-step explanation:
This question can be solved using a system of equations.
I am going to say that:
x is the amount of white paint used.
y is the amount of blue paint used.
7.7 pints of blue paint and white paint to paint her bedroom walls.
This means that
1/4 of this amount is blue paint, and the rest is white paint.
The rest is 1-(1/4) = 3/4. That is, the amount of white paint is the triple of the amount of blue paint. That is, , or
Replacing in the first equation:
She used 5.775 pints of white paint to paint her bedroom walls.
Answer:
b) Find the measurements of a rectangk with a perimeter of
26cm and an area of 1600cm
There is no way to get an area of 1600 cm using a perimeter as small as 26 cm.
Step-by-step explanation:
perimeter = 2(L + W) = 26, then L + W = 13, so L = 13 - W
area = L x W = 1600
substitute for L:
(13 - W)W = 1600
13W - W² = 1600
-W² + 13W = 1600
-W² + 13W - 1600 = 0
W² - 13W + 1600 = 0
