Answer:
the price for each doughnut is $1.05
Step-by-step explanation:
doughnuts = d
cookies = c
2d + 3c = $3.30
5d + 2c = $4.95
to find the answer multiply 2 with the first equation, and multiply -3 with the second equation.
4d + 6c = 3.30
-15d - 6c = -14.85
combine like terms
-11d = -11.55
divide by -11
d = 1.05
Answer:
Yes
Step-by-step explanation:
44 is 100%
100% + 100% + 50% = 250%
44 + 44 + 22 = More than 100
Answer:
4, 6, 8, 10, 30
Step-by-step explanation:
1: -5 = 3m + c
2: -2 = 0 + c
From equation 2, we knew c = -2
So we sub into equation 1 and got the value of m
-5 = 3m - 2
m = -1
The equation of line is y = -x - 2
