Answer:

260 in economy

100 in business

Step-by-step explanation:

ok so out of 18 seats 13 are economy and 5 are business and since 18 times 20 is 360 we multiply each of these by 20 so 13 times 20 is 260 20 times 5 is 100 there you go

erastovalidia [21]

Answer:

f=2

Step-by-step explanation:

0.3+0.5f-0.7

Move the varibale (0.5f) to the left-hand side and change it's sign to negative.

-0.5+0.3+-0.7

Move the constant to the right hand side and change it's sign

-0.5f=-0.7-0.3

Calulate the differnce

-0.5f=-1

divide both sides by -0.5

F=2

A student is making cookies for a bake sale. He sells 8 snickerdoodles and 12 chocolate chip
lions [1.4K]

Answer:

Snickerdoodles are 0.22$ each and chocolate chip are 0.43$ each

Step-by-step explanation:

using the information in the problem, you can make 2 separate equations: 8x+12y=6.92 and 5x+5y=3.25, let x= the cost of a snickerdoodle and y= the cost of a chocolate chip cookie.

With the 2 equations, we can isolate the y variable of the first equation and simplify which will give us y= -2/3x +6.92/12.

You can now take that equation and plug it into equation number 2:

5x+5(-2/3x + 6.92/12)=3.25.

solve that equation by multiplying 5 through the brackets: 5x-10/3x+34.6/12=3.25

add common terms: 5/3x=4.4/12

find the value of x, you will get x=0.22

plug the value of x (0.22) into one of your equations and solve for the y-value
