Answer:
(-2,-5)
Step-by-step explanation:
y = 2x-1
3x-y = -1
We can use substitution
3x - (2x-1) = -1
Distribute the minus sign
3x -2x+1 = -1
x +1 =-1
Subtract 1 from each side
x+1-1 = -1-1
x=-2
Now we need to find y
y = 2x-1
y = 2(-2) -1
y = -4-1
y = -5
(-2,-5)
Answer: 5-lb bag for $12.99
Step-by-step explanation: I multiplied 2 x 2.5 and 5.39 x 2.5. It was more than $12.99. This means that the 5 pound bag is less expensive.
Substitute the values of x to find y. Example:
So do that for the other values of x.
Answer:
No, it will not be enough.
Step-by-step explanation:
Hello!
This estimation is incorrect, as 5.68 would round up to 6, and 4.1 would round down to 4.
Multiplying them both will give us 24, which can be justified as the actual product is 23.29.
Therefore the estimation of $20 will not be enough for 4.1 pounds of cherries.
