Answer:
The price for a small glass of milk is $0.95, and the price for a breakfast taco is $1.15.
Step-by-step explanation:
Let the price of a taco be x and the price for a small glass of milk be y.
Multiply the first equation by 2:
Subtract the new third equation from the second equation:
Hence, the price for a small glass of milk is $0.95.
Substitute y into the first equation.
Therefore, the price for a breakfast taco is $1.15.

Answer:
x = 14
Step-by-step explanation.
First I would use sine to find x's value. So ----> sin(30) = 7/x ----> x sin(30) = 7 ----> x = 7/sin(30) = 14.
You Can also find that x is equal to 14 by applying the 30, 60, 90, triangle rule. Becuase '7' opposes the 30 degree angle it is 1/2 the hypotenuse, if thats the case just multiply the 7 by 2 and you have the hypotenuse length.
Answer:
6 hours
Step-by-step explanation:
Let
x----> the number of hours worked at the donut shop
y----> the number of hours worked at the school bookstore
we know that
x+y=20
x=20-y -----> equation A
10.25x+8.75y=196 -----> equation B
Substitute equation A in equation B and solve for y
10.25(20-y)+8.75y=196
205-10.25y+8.75y=196
10.25y-8.75y=205-196
1.5y=9
y=6 hours at the school bookstore
