932 multiply the # of weeks in a year which is 1 year = 52 weeks
Answer:
Step-by-step explanation:
Let the amount of carbohydrates in chicken sandwich be x
The amount of carbohydrates in salad will be 2x + 10
(x ) + ( 2x + 10) = 100
x + 2x + 10 = 100
x + 2x = 100 - 10
3x = 90
x = 90 / 3
x = 30
Therefore chicken sandwich has 30 grams of carbohydrates.
Salad will have:
2 (x) + 10 → 2 (30) + 10 → 60 + 10 = 70
Salad has 70 grams of carbohydrates.
The "no thinking required" way to solve it is using the quadratic formula. That formula tells you the solution to
is given by
Your equation has a=-2, b=3, c=-9, so the solution is
The solutions are complex numbers.
