Ariel made cupcakes to sell. 2/3 of them were chocolate chip,25% of the reminder was strawberry and the rest were 90 vanilla cup
Anton [14]

Answer:

Let x be the total number of cupcakes.

Chocolate chips =

\frac{2}{3} x

Strawberry =

\frac{1}{4}  \times  \frac{1}{3}  \\  =  \frac{1}{12} x

Vanilla =

x -  \frac{2}{3} x -  \frac{1}{12}x \\  =  \frac{1}{3} x -  \frac{1}{12} x \\   =  \frac{1}{4} x

given

\frac{1}{4} x = 90

x = 90 \div  \frac{1}{4}  \\  = 90 \times 4 \\  = 360

a)Number of Chocolate chip Cupcakes =

\frac{2}{3}  \times 360 \\  = 240

b)Number of Strawberry cupcakes =

\frac{1}{12}  \times 360 \\  = 30

3/4x + 4/7y = 5/4x -1...solve for y​
Zielflug [23.3K]

Answer:

\frac{3}{4} x +  \frac{4}{7} y =  \frac{5}{4} x - 1 \\  \frac{4}{7} y =  \frac{5}{4} x - 1 - \frac{3}{4} x \\  \\  \frac{4}{7} y =  \frac{5x - 4 - 3x}{4}  \\  \frac{4}{7} y =  \frac{2x - 4}{4}  \\  \\ y = \frac{2x - 4}{4} \div   \frac{4}{7} \\ y =  \frac{2x - 4}{4} \times  \frac{7}{4}  \\  \\ y =  \frac{14x - 28}{16}  \\  \\ y =  \frac{14x}{16}  -  \frac{28}{16}
