Answer:
266
Step-by-step explanation:
if a 45 minute workout is 1000 calories, at the same rate, a 12 minute workout would be 266 calories and 2 thirds. 
x 1000 = 266
-7x - 2y = 19
4x + y = -12
Set y equal to each other (opposite signs are fine and you could also set x equal instead of y)
-7x - 2y = 19
8x + 2y = -76
Add equations together
x = -52
Plug x value into an equation
4(-52) + y = -12
Solve for y
-208 + y = -12
y = 196
Hope this helps! ;)
You have to divide the 14 pieces amongst 4 friends: 14/4. This can be simplified into a fraction. Since both the numerator and denominator can be divided by 2, you can simplify the fraction to 7/2 and make it into a mixed number 3 1/2, or decimal form 3.5. Each friend got three and a half pieces of banana bread.
