Step-by-step explanation:
Answer:
14 x + 1
Step-by-step explanation:
You aren't dumb, your teacher can't teach!
First we must add the x values together:
8x - 7 + 6x + 8
8 + 6 = 14
14x -7 + 8
Now we add the constants (regular numbers):
14x -7 + 8
-7 + 8
14x +1
There we go!
8x -7 + 6x +8
is
14x +1
Philip's rectangular deck is 5 yards wide. The ratio of the width to the length is 4 to 5. What is the approximate length of Philip's deck in feet? Hint: 1 yard = 3 feet.
Answers
Answer:
18.75 feet
Step-by-step explanation:
Step 1
we find the length of Philip's rectangular deck in yards
The ratio of the width to the length is 4 to 5.
Philip's rectangular deck is 5 yards wide.
Hence,
Hence:
4/5 = 5/x
Cross Multiply
4x = 5 × 5
4x = 25
x = 25/4
x = 6.25 yards
The length of Philip's field = 6.25 yards
Hint: 1 yard = 3 feet.
Converting the yard to feet
1 yard = 3 feet
6.25 yards = x
Cross Multiply
x = 6.25 × 3 feet
x = 18.75 feet
Therefore, the length of Philip's field in feet = 18.75 feet

A rectangular field is to be enclosed by a fence and divided
into two parts by another fence. Find the maximum area
that can be enclosed and separated in this way with 800 m
of fencing
Answers
Answer:
80000 square meters
Step-by-step explanation:
perimeter + dividing fence = 800
let a = length
let b = width
let c = length of dividing fence
perimeter = 2*a + 2*b
let's say...
c is the same as the length
2a + 2b + c = 800
2a + 2b + a = 800
3a + 2b = 800
area = length*width
area = a*b
area / b = a
3*(area/b) + 2b = 800
3*(area/b) = 800 - 2b
area/b = (800 - 2b)
area = (800 - 2b)*b
To make the area large, we make the right hand side large.
800b - 2b^2
If you put in terms of x, y it looks like a downward opening parabola, so the max area is at the vertex. Half way between the roots.
y = -2x^2 + 800x
y = -x^2 + 400x
0 = x*(-x + 400)
roots are x= 0 and x = 400
vertex is at x, aka b = 200
area at b=200 is (800 - 400)*200 = 80000
and a is area/b... 80000/400 = 200

With a beginning balance of $1200 and no additional charges during the next three months, you will just pay the minimum payment each month for the next three months. The APR is 24.99% and the minimum payment each month is 3% of the balance.
Answers
Here is the complete question.
With a beginning balance of $1200 and no additional charges during the next three months, you will just pay the minimum payment each month for the next three months. The APR is 24.99% and the minimum payment each month is 3% of the balance. Determine the finance charge, new balance, and minimum payment required for each of the next three months, and the starting balance for month 4 in the table below.
a) What is the total of minimum payments?
b) What is the total sum of the finance charges?
c) How much does the starting balance decrease after these three payments?
d)The total of your finance charges is what percent of our total payments?
Answer:
Step-by-step explanation:
Month Beginning Finance New Minimum
Balance Charge Balance Payment
1 $ 1200 24.99 1224.99 36.75
2 1188.24 24.75 1212.99 36.39
3 1176.60 24.50 1201.10 36.03
4 1165.07 24.26 1189.33 35.68
a.
The total minimum payments for 3 months = 36.75 + 36.39 + 36.03
The total minimum payments for 3 months = $ 109.17
b.
Total finance charges for 3 months = 24.99 + 24.75 + 24.50
Total finance charges for 3 months = $ 74.24
c. The starting balance decrease from 1200 to 1165.07, this implies that there is a reduction of $ 34.93
d. The total of finance charges = 74.24×(100/109.17)
The total of finance charges = 68% of total payments.

Darnell's car used 8 gallons of gasoline to travel 340 miles. After a mechanic worked on the car, it used 7 gallons of gasoline to travel 350 miles. How many more miles per gallon did Darnell's car travel after the mechanic worked on it?
Answers
Answer:
7.5 miles per gallon
Step-by-step explanation:
Given that:
8 gallons of gasoline traveled 340 miles
After being worked on by the mechanic :
7 gallons travels 350 miles
How many more miles per gallon did Darnell's car travel after the mechanic worked on it?
Obtain the unit mile traveled per gallon before and after the mechanic worked on the car :
Miles per gallon before being worked on by mechanic :
340 miles / 8 gallons = 42.5 miles per gallon
Miles per gallon after being worked on by mechanic :
350 miles / 7 gallons = 50 miles per gallon
(50 - 42.5) = 7.5 miles per gallon
Hence, vehicle moved 7.5 more miles per gallon after bwing worked on by mechanic.

32y = 1000
32y ÷ 32 = 1000 ÷ 32
y = 31.25
1) The value of y varies directly with x. If x = 3, then y = 13.
Show your work for finding the value of x when y = 39?
Answers
Answer:
When y is 39 x is 3.
Step-by-step explanation:
Proportions!
x = 3
y = 13
We need to find our multiplier first. How did 13 turn into 39?
39/13 = 3
13 * 3 = 39
We multiplied by 3!
Now we multiply x by three to keep the propotion, proportional!
x= 3
(3) * 3 = 9
Now we make the proportion
3 : 39
When y is 39 x is 3.
