I can't help you because I'm also stuck on this question for mathematics in middle school, and it's hurting my brain just trying to figure it out :[
Michael read 135 pages in 90 minutes. Select all of the rates that have the same constant rate of change as Michael's rate. 180 pages in 2 hours 180 pages in 2 , hours 60 pages in 30 minutes 60 pages in 30 , minutes 108 pages in 212 hours 108 pages in 21 half , hours 150 pages in 1 hour 150 pages in 1 , hour 225 pages in 150 minutes 225 pages in 150, minutes 210 pages in 2 hour 20 minutes
Answer:
180 pages in 2 hours
225 pages in 150 minutes
210 pages in 2 hours 20 minutes
Step-by-step explanation:
135 pages : 90 minutes
= 135/90
= 3/2
= 3 : 2
180 pages : 2 hours
180 pages : 120 minutes
= 180/120
= 3/2
= 3:2
60 pages : 30 minutes
= 60/30
= 2/1
= 2:1
108 pages : 2 1/2 hours
108 pages : 180 minutes
= 108/180
= 18/30
= 3/5
= 3:5
150 pages : 1 hour
150 : 60
= 150/60
= 10/6
= 5/3
= 5:3
225 pages : 150 minutes
= 225/150
= 9/6
= 3/2
= 3:2
210 pages : 2 hours 20 minutes
210 pages : 140 minutes
= 210/140
= 3/2
= 3:2

HELP, NO SCAM ANSWERS PLEASE!
Answer:
c = 2.99m+ 6.85
Step-by-step explanation:
one time fee of 6.85
2.99 per movie rental
in other words you must pay 6.85
and 2.99 times the number of movies you watch
m = movies watched
c = cost
therefore
c = 2.99m+ 6.85
watching 13 movies at movie mania would mean that m (movies watched) would be 13
put that into the equation:
c = 6.85+ 2.99(13)
c = 6.85+ 38.87
c = 45.72

Help me find the value of "y" thanks
Answer:
[tex]y=3x-8[/tex]
Step-by-step explanation:
First, you have to isolate y on one side of the equation.
Step 1) Add 5 to both sides (this will cancel out the (-5) on the left)
Step 2) Subtract 3x from both sides (this will cancel out the (3x) on the left)
Step 3) Subtract y from both sides
Step 4) In order to make the desired variable positive, change the sign of everything in the equation
The step shown above will yield the answer of [tex]y=3x-8[/tex]

Find the x- and y-intercepts of

In the diagram if AE = AB, find the area shaded.
Answer:
Area shaded = 60 [tex]cm^{2}[/tex].
Step-by-step explanation:
From the given diagram,
Area shaded = Area of the trapezoid EBCD
Given that: AE = [tex]\frac{1}{3}[/tex]AB
= [tex]\frac{1}{3}[/tex] x 12 (∵ AB = CD = 12 cm)
= 4 cm
AE = 4 cm,
Thus,
EB = (12 - 4) cm
= 8 cm
EB = 8 cm
Area shaded = [tex]\frac{1}{2}[/tex] (EB + CD) x AD
= [tex]\frac{1}{2}[/tex] (8 + 12) x 6
= (20) x 3
= 60
Area shaded = 60 [tex]cm^{2}[/tex]
