Answer:
From left to right:
3, 30, 20
Step-by-step explanation:
Start by determining the ratio of yellow to red paint. Use the column where both amounts are given:
yellow to red = 2 to 6 = 1 to 3
2 to 6 the same as 1 to 3 when reduced, by dividing both sides by 2.
This means yellow paint is a third of red paint. Backwards, red paint is three times yellow paint.
To go from yellow to red, do yellow X 3.
To go from red to yellow, do red ÷ 3.
Column 1:
1 X 3 = 3
Column 3:
10 X 3 = 30
Column 4:
60 ÷ 3 = 20
The ratios are:
1 to 3
2 to 6
10 to 30
20 to 60
25 kids in all
2xboys:3x girls
so the equation would be
2x+3x=25
solve,
5x=25
/5 /5
x=5
2x=10
3x=15
10 boys and 15 girls
Simply you would do
45+10 time the number of days
So
45+10 x 2 and then you would put the answer in the next Collin
First we need to figures it how much centimeters is in the cylinder . The bottom is 20 centimeter meters and the side is 110 centimeters. Take out the zeros and do 11 x 2, that equals 22, then put the 2 zeros back in. So the cylinder has a mass of 2200 centimeters. We want to fill half of the cylinder, so divided 2200 by 2 and that is 1100 centimeters. And 1100 is the answer to this equation.
