4’11 is the average hieght to ride both rides
Answer:
<h2>x = -2 (verified by algebra) ✅</h2>
Step-by-step explanation:
Since we are given the value of y, we can replace it with 5x + 7.
We now have: 3x + 5x + 7 = -9
We can now simplify by adding 3x and 5x to get 8x.
8x + 7 = -9
We can subtract 7
8x = -16
And now, we divide by 8
x = -2
We can check to make sure we are correct
3(-2) + 5 (-2) + 7 = -9
-6 + -10 + 7 = -9
-9 = -9 ✅
Answer:
RST = 20
Step-by-step explanation:
a ray that divides an angle into two equal angles is called an angle bisector.
So RSP = PST
3 x -2 = 9x - 26
6x = 24
x = 4
RST = 3x -2 + 9x -26 = 20
Answer: h=3v/pir^2 +1
Step-by-step explanation:
sorry i can't use the pi symbol so i'll be referring to pi as pi
^2 is squared
1/3pir^2(h-1) =v
<u>simplify 1/3pir^2</u>
pi/3r^2(h-1)=v
<u>multiply both sides by 3 and simplify </u>
3*pi/3r^2(h-1)=3v <-- simplify = pir^2(h-1)=3v
<u>divide both sides by pir^2</u>
pir^2(h-1)/ pir^2 = 3v/ pir^2
<u>simplify </u>
h-1 = 3v/pir^2
<u>add 1 to both sides</u>
h-1 +1 = 3v/pir^2+1
answer/ simplify:
h=3v/pir^2 +1
