2(3+y)+y=3
6+3y=3
Y=-1
Substitute to solve for x
X=3-1
X=2
Answer:
4x=100+6x=216=
Step-by-step explanation:
100+216=316 and 4x+6x= 10
316/10 = 31.6
Y=-3x+2:
Already in slope intercept form
Graph by plotting a point on (0,2)
Then move 3 points up and 1 to the right and plot the point and keep doing that a couple times
-3x-y=-2:
Add -3x on both sides
The result would be
-y=3x-2
Divide everything by negative 1
Y=-3x+2
Both equations are the same so they are the same line
Answer:
$48.30
Step-by-step explanation:
If the dinner was $42.00 and they wanted to give a 15% tip, then to find that start by multiplying 42 by 0.15
42.00 x 0.15 = 6.3
now add $6.30 to $42.00
42 + 6.3 = 48.3
