Answer:
x = -2, y = -9
Step-by-step explanation:
You can substitute the value of y into y. The first equation shows that y is equal to 4x -1, so we can switch this with the y in the second equation.
y = 2x -5 will become
4x - 1 = 2x - 5
Add 5 to both sides
4x + 4 = 2x
Subtract 4x from both sides
4 = -2x
Divide both sides by -2
-2 = x
Now we plug this number into an equation to find y.
y = 4x - 1 becomes
y = 4(-2) - 1
Simplifying it, we have:
y = -8 - 1
y = -9
Answer:
11
Step-by-step explanation:
you have to round the decimal 5 to the top to get a whole number which is 11 , and I'm guessing 10 grown trees and a little one
4q + 8 - 6= 4q + 2=2q + 1
Answer:
$22.68
Step-by-step explanation:
Meal Price =$18
Sales tax =6%
Tip = 20%
Total Price of the Meal =$18 + (6% of 18)+ (20% of 18)
=$18 + (0.06 X 18)+ (0.2 X 18)
=18+1.08+3.6
=$22.68
The total price of Alyssa's meal is $22.68.
