Answer: $30.44
Step-by-step explanation:
$30 20% of tht is 6
30-6=24
tax is 6.4% which is 1.94
24+1.94 which equals $25.94
tips is 15% 4.5 so we add that to $25.94
so total is $30.44
3x + 4y = 16
-4x - 3y = -19
4( 3x + 4y = 16)
3( -4x - 3y = -19)
Distribute
12x + 16y = 64
-12x - 9y = -57
Now subtract both equations
7y = 7
/7 on both sides
y = 1
Substitute y = 1 in one of the equations.
3x + 4y = 16
3x + 4(1) = 16
-4 on both sides
3x = 12
/3 on both sides
x = 4
Answer:
x = 4
y = 1
Answer:
y=(1/2)x+4
Step-by-step explanation:
you have 2 points but in order to find slope intercept you need slope so,
(y2-y1)/(x2-x1)
(-1+4)/(8-2)=1/2 =slope
slope intercept:
y-y1=m(x-x1)
y-2=(1/2)(x+4)
y-2=(1/2)x+2
y=(1/2)x+4
Answer:
(4;0)
Step-by-step explanation:
y=0
2x-3×0=8
2x=8
x=4
Answer: you need 5000 more
Step-by-step explanation: 70000 + 5000= 75000
