Answer: x=10 and y=5
Step-by-step explanation: Let be the number of hours worked by the first mechanic.
Let be the number of hours worked by the second mechanic.
They worked for a combined total of hours. So we have the following equation.
The first mechanic charged per hour and worked for hours.
So, the first mechanic charged dollars.
The second mechanic charged per hour and worked for hours.
So, the second mechanic charged dollars.
Together they charged a total of . So we have the following equation.
The two equations above give us a system of linear equations.
We can solve the first equation for .
We then substitute for in the second equation to find .
Answer:
17
Step-by-step explanation:
12 1/2 -(-4 1/2) = 12 1/2 + 4 1/2
=25/2 + 9/2
= 34 /2
= 17
The problem ask to find the work done of the gorilla reaches that height of 20 ft in 10s and 5s if the gorilla has a mass of 360lb. So base on that data allow, you can solve the work by multiplying the force and the distance, and force is calculated by multiplying mass and acceleration and acceleration is calculated by velocity over time. So the answer would be that force is 7200 N
30. you can model this with an equation and solve, x being the smallest number and the x+1 and x+2 representing the consecutive numbers.
x+(x+1)+(x+2)=93
3x+3=93
3x=90
x=30
x+1=31
x+2=32
30+31+32=93
