Answer:
MRS. White graded 51 papers.
Step-by-step explanation:
85/100= 0.85
0.85 x 60 = 51
Answer:
About 72 degrees
Step-by-step explanation:
Answer:
y = 5x - 21
Step-by-step explanation:
Since we already know the slope, all we need to do is plug the values of x and y into the equation.
y = 5x + b
-1 = 5(4) + b
-1 = 20 + b
-21 = b
The equation is y = 5x - 21.
The teachers plan will raise money is 1.8 times the static graders plan.The teachers plan to raise a dollar is 5/6 times the static graders plan to raise a dollar.More dollars will be raised by the teachers plan compared to the static graders plan.
Step-by-step explanation:
In the question,
Let what the static graders plan to rise to be $x.
Let what the teachers plan to rise to be $ y
You understand that ;
y =210 +x ----------------(this is 210 dollars more than the static graders raise)
y=x+4/5 x -------------------(but only 4/5 as much as the static graders)
Solving the equations to get x and y
210+x=x+4/5x
5(210+x)=5*x+4x
1050+5x=5x+4x
1050=5x+4x-5x
1050=4x
1050/4=4x/4
x=$262.50
y=210+262.50=$472.50
Additionally, for every $60 raised in teachers plan, the static graders raise $50
This means in teachers plan 1$ raised equals 5/6$ raised in static plan
y=5/6x
