Answer:
7n + 5 − 9n = 8 − 2n − 3 = true
-2 n + 5 = 5 - 2 n = true
Step-by-step explanation:
Left-hand side:
Simplify the following:
7 n - 9 n + 5
Grouping like terms, 7 n - 9 n + 5 = 5 + (7 n - 9 n):
5 + (7 n - 9 n)
7 n - 9 n = -2 n:
Answer: -2 n + 5
____________________________
Right-hand side:
Simplify the following:
-2 n - 3 + 8
Grouping like terms, -2 n - 3 + 8 = (8 - 3) - 2 n:
(8 - 3) - 2 n
8 - 3 = 5:
Answer: 5 - 2 n

Sue used to have a square garage with 286 ft squared of floor space. He recently built an addition to it. The garage is still a square, but now it has 50% more floor space. What was the length of one side of the garage originally? What is the length of one side of the garage now? What was the percent increase in the length of one side?
Answer:
New Length = 20.71 feet
Original Length = 16.91 feet
22.47%
Step-by-step explanation:
Original area of the square garage = 286 ft squared
Addition of 50% more space
New area of the garage = 286 + .50(286)
= 286 + 143
= 429 square feet
What was the length of one side of the garage originally?
Original area of the square garage = 286 ft squared
Area of a square = length^2
286 = length^2
Find the square root of both sides
√286 = √length^2
Original Length = 16.91 feet
What is the length of one side of the garage now?
New area of the garage = 429 square feet
Area of a square = length^2
429 = length^2
Find the square root of both sides
√429 = √length^2
New Length = 20.71 feet
What was the percent increase in the length of one side?
(New length - old length) / old length × 100
= (20.71 feet - 16.91 feet) / 16.91 feet × 100
= 3.8 feet / 16.91 feet × 100
= 0.2247 × 100
= 22.47%

Jason has three more than four times the amount of money that Jeff has. Together they have $72 How much does each person have?
Answer:
$58.20$13.80Step-by-step explanation:
Let Jason's money be x and Jeff's money be y
x = 4y + 3x + y = 72Substitute x in the second equation
4y + 3 + y = 725y = 69y= 69/5y = $13.80Then
x = 4*13.8 + 3 = $58.29 — 3x = у

Find the measures of the labeled angles
Answer:
135 degrees \
Step-by-step explanation:
5x= x+108
Subtract x from the right
4x= 108
divide by 4
x= 27
Substitute for x in the original equation
(x+108)
(27)+(108)
= 135 degrees
Solve the inequality.−2(x − 3) − 4 ≥ 3x − 5(x − 1)
Answer:
0>3 i hope it helps
Step-by-step explanation:
Let's solve your inequality step-by-step.
−2(x−3)−4>3x−5(x−1)
Step 1: Simplify both sides of the inequality.
−2x+2>−2x+5
Step 2: Add 2x to both sides.
−2x+2+2x>−2x+5+2x
2>5
Step 3: Subtract 2 from both sides.
2−2>5−2
0>3

The voltage V required for a circuit is given by [tex]v=\sqrt{PR}[/tex] , where P is the power in watts and R is the resistance in ohms.
How many more volts are needed to light a 100-watt light bulb than a 75-watt light bulb if the resistance of both is 110 ohms? Round answer to the nearest tenth.
Answer:
✓11000-✓8250=~ 14 volts
Step-by-step explanation:
the answer is the difference by 100-watt light bulb to a 75 light bulb.
so, all you have to do is this:
v1-v2--------> ✓PR-✓P2R2
so you'll have ✓100.110-✓75.110= ✓11000-✓8250= 14

Write the equation of the line through the points (-3, 9) and (4, 2) in POINT-SLOPE FORM
Answer:
y-9=-1(x+3)
Step-by-step explanation:
The formula for point slope is y2-y1=m(x2-x1). So, we can use the values of the given points to solve the equation for m, or, the slope. We get an equation with the result of 2-9=m(4+3), which gives us the slope as -1. Now, substitute your xy values back in, to get the equation
