1) there are a total of 144 cycles 2) there are a total of 378 pedals
3) there are a total of 320 wheels
A. Write 3 equations, using b, t, z, representing the three things the work-
er noticed.
Equation 1: b+t+z=144
Equation 2:
262t+4z=378
Equation 3: 26-3t+27=320
B. Figure out how many bicycles, tricycles, and tandem bikes are in the
shop on that day using the solving systems methods we have discussed in
class.

Sherina wrote and solved the equation. x-56=230 x-56-56=230-56 x=174 what was sherina’s error? sherina’s work is correct. sherina only needed to subtract 56 from 230. sherina made a subtraction error when subtracting 56 from 230. sherina should have added 56 to both sides of the equation.

How can you find the conditional probability of a given b as the fraction of b’s outcomes that also belong to a, and interpret the answer in terms of the model? i just need a good explanation

You are updating your garage and the only thing left to paint is your garage day. you're only going to paint the slide that faces the street. the garage door is 9 fert 8inches tall and 120 inches wide. you need to know the surface area of the side of the garage door to determine how much paint to buy. the hardware store sells paint by how much covers a square foot. what is the surface area you should report to the hardware store what is the answer
