r
15.5 (not the one with the line under it i just couldnt find the one that didnt have the line under it)
for the graph, put 16 on the right side and label the lines right to left 16 15.5 14 14.5 etc. Put an open circle on the 15.5 line. then make an arrow pointing to the left.
10:
80p+64
This is because she needs 80 points OR MORE and (p represents the points) she already has 64. She needs 80 to be less than or equal to the amount of points earned.
The solution is 16p because 80-64=16 and p is needs to be greater than or equal to 16
We see that the shape is made up of 2 shapes:
trapezoid and triangle
(trapezoid is on top of upside down triangle)
area of trapezoid=(1/2)(b1+b2)(h)
area of traignel=(1/2)(b)(h)
area of trapezoid
b1=14
b2=18
h= ok so total height=17 and 12 is taken up by triangle os therefor h=17-12=5
A=(1/2)(14+18)(5)
A=(1/2)(32)(5)
A=(16)(5)
A=(80)
now area of triangle
H=12
B=18
A=(1/2)(18)(12)
A=(9)(12)
A=108
add
80+108=188
total area=188mm^2
Answer:
9.94*1/7.1= 1.4 acres
Step-by-step explanation:
You then would eliminate 6, by adding 6 to both sides
Then you want all of the X's on the same side, so you subtract 2x from both sides.
Then to isolate the X, you divide by 2
The answer is x=2
