Answer: You need a grade of 78 on the final exam to earn a final grade average of at least 87 in each grading system.
Step-by-step explanation:
(85 + 90 + 95 + x)÷ 4 =87
Simplify:
(270 + x) ÷ 4 = 87
Rearrange:
(x + 270) ÷ 4 = 87
Multiply terms to Reduce:
4((x + 270) ÷ 4) = 4 * 87
Cancel Multiplied terms in Denominator:
x + 270 = 4 * 87
Multiply:
x + 270 = 348
Subtract 270 on both sides of the equation:
x + 270 - 270 = 348 - 270
Simplify:
x = 78
q(x=f(x-h+k
here, h=0, k=-8, so
to translate f(x) 8 units down, we have
q(x)=f(x-0)-8
=2x^2-3x+5-8
=2x^2-3x-3
Answer:
The length of fencing will be 
Step-by-step explanation:
Step 1
Find the dimensions of the rectangle
we know that
The area of a rectangle is equal to

In this problem we have

so
-----> equation A
-----> equation B
Substitute equation B in equation A

square root both sides

Find the value of b
-----> 
step 2
Find the length of fencing
The perimeter of a rectangle is equal to

we have


substitute

Liters because mililiters are too small to measure gallons of water
