Answer:

The number of days when Kimmy play for two hours a day is 3.

Step-by-step explanation:

Let the number of days when Kimmy play for two hours a day be x. So, the number of days when Kimmy play for three hours a day is 9-x.

It is given that Kimmy has played video games 24 hours over the last 9 days.

2(x)+3(9-x)=24

2x+27-3x=24

-x+27=24

Subtract 27 from both the sides.

-x=24-27

-x=-3

x=3

Therefore the number of days when Kimmy play for two hours a day is 3.

Kensington City Cafe recently introduced a new flavor of coffee. They served 28 grande cups
Dmitrij [34]

Answer:

jumbo 23 oz, grande 16 oz

Step-by-step explanation:

Use g for grande and j for jumbo

The first equation: 28g + 33j = 1207

The second equation: 28g + 53j = 1667

Subtract the first from the second

   28g + 53j = 1667

-   28g + 33j = 1207

Equal 20j = 460

j = 23

Put 23 in for j in either equation and solve for g:

28g + 33(23) = 1207

28g + 759 = 1207

28g = 448

g = 16
