Answer:
Step-by-step explanation:
Use a proportion.
2.2/5.5 = 48/x
2.2x = 5.5 * 48
2.2x = 264
x = 120

87.5 teaspoons
Step-by-step explanation:
Given that a mixture of purple paint contains 6 teaspoons of red paint and 15 teaspoons of blue paint.
So, Purple paint : Blue paint = 6 :15
To make the same shade the ratio of purple and blue paint must be the same.
In the new mixture, the amount of purple paint =35 teaspoon.
let the amount of red paint =x teaspoon.
So, in the new mixture,
Purple paint : Blue paint = 35 : x
So, to make the same shade, the ratio of purple and red paint must be the same, i.e
35 : x = 6 :15


Hence, 87.5 teaspoons of red paint required to mix with 35 teaspoons of purple paint to make the same shade.
Answer:
Step-by-step explanation:
We can use the process of elimination as
5x + 4y = 24
5(x + 7y = 11) —> 5x + 35y = 55
5x + 4y = 24
-(5x + 35y = 55)
—————————
-31y = -31
-31y/-31 = -31/-31
y=1
Answer: the fractional increase is 1/5
Step-by-step explanation:
The initial area of Julio's living room was 1000 sq. ft. Then he added a room that was 20 ft. by 10 ft. The area of the room that was added to the living room would be
20 × 10 = 200 square feet
The new area of the room would be
1000 + 200 = 1200 square feet
Therefore, the fractional increase of the living space would be
Increase in area/original area
It becomes
200/1000 = 1/5
