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:
y = 2x - 5
Step-by-step explanation:
The slope for a parallel line is the same as the slope in the given equation. Therefore the slope of the new line will be 2 m= 2
use that slope and (2, -1) to find b
-1 = 2(2) + b
-1 = 4 + b
-5 = b
Plug m and b into y = mx + b
y = 2x - 5
5/9
5 times 4= 20
12 times 3=36
20/36=5/9
Answer: b
Step-by-step explanation:
you start with 0 min- equals 24
1 min- 21
2 min- 18
3 min- 15
4 min- 12
5 min- 9
and so on- you look for the table that best describes that. x represents the minutes, and y represent the amount of water left in the sink.
Answer:
Y = 7
Step-by-step explanation:
You would add 4 to both sides to cancel out the -4. That leaves y by itself equaling 7.
