Answer:
8 tricycles
Step-by-step explanation:
Make a system of equations
Let t represent tricycles, and b represent bicycles
We know that tricycles have 3 wheels, bicycles have 2, and there are a total of 64 wheels
We also know each has one rider, and there are a total of 28 riders
3t+2b=64
t+b=28
Subtract t from both sides in the second equation. This will allow us to use substitution
b= -t+28
Substitute -t+28 in for b in the first equation
3t+2b=64
3t+2(-t+28)=64
Distribute the 2
3t + 2*-t+ 2* 28 =64
3t-2t+56=64
Combine like terms
t+56=64
Subtract 56 from both sides
t=8
There were 8 tricycles
Answer:
If the ratio is 1:3 and there are 9 violas, all you have to do is multiply 9 × 3 to get 27.
Answer:
26
Step-by-step explanation:
The triangle equals 180 degrees the two measurements we already have is 90 degrees (the right angle) and 64 degrees.
90+64=154 and 180-154=26.
So 26 is your answer because 90+64+26=180
Hope this helps!
Answer:
Latisha rode 16 rides
Step-by-step explanation:
Look at picture attached. Have a blessed night!
Just slope intercept formula (y=mx+b). X represents the number of rides so you will need to myltiply that by $2.50. $9 is a one time fee so that would be of the b of the equation. That all equals the total Latisha piaid, $49. Then solve like so.
