The answer would be C. She bought four applications for 2.99 each. you would multiply 2.99 x 4 to get 11.96. X would be the variable and we don’t know how many apps she bought for 1.99 so we would do 1.99 by however many apps she bought and 11.96 of the four apps she bought to find the total. this gets the answer of y = 1.99x + 11.96
Just a generic answer would by 12/8 or any other multiple of the numbers. If that is a fraction than same goes as above.
Answer:
4a+24
Step-by-step explanation:
a+6+a+6+a+6+a+6 collect the like terms with a and 6
4a+24
A gallon is 4 times larger than a quart because there are 4 quarts in 1 gallon!
The ratio of the lengths is 75 : 25 or 3 : 1
The ratio of and area is the square of this: ie 9 : 1 or 75^2 : 25^2
(In working out the area the radius is squared)
The ratio of the volumes is the cube of this: ie 27 : 1 or 75^3 : 25^3
(In working out the volume the radius is cubed)
Hopefully this explains it
