Answer:
a. -24
Step-by-step explanation:
Multiply by 6 ...
2/3(1/2x+12)=1/2(1/3x+14)-3
4(1/2x +12) = 3(1/3x +14) -18 . . . . . . multiply by 6
2x +48 = x +42 -18 . . . . . . . . . . . . . .eliminate parentheses
x = 24 -48 = -24 . . . . . . . . . . . . . . . . simplify and subtract (x+48)
So first you need to do the discount
(95)(0.9) = 85.5
then add the 4.5% sales tax:
(85.5)(1.045) = $89.35
Answer:
40 meters
Step-by-step explanation:
since a =b*h
area - a
base - b
height - h
so a/h = b (
)
plug in area and height
160/4 = 40 (meters)
hope this helps:)

ANSWER: y= -4x+1
slope-intercept form is y=mx+b
to find m, which is the slope, we used
m=(y2-y1)/(x2-x1) (rise over run)
=(-15-(-3)/4-1)
= -12/3
= -4
to find b, choose one of the points and use the slope -4 and plug it in:
y=m(x)+b
-3= -4(1)+b
-3= -4+b
1=b
