Answer:
X=5
Step-by-step explanation:
Collect like terms then move the terms. Then collect liked terms. Calculate and Chang signs
Answer:
X = 5
Remember, x has a hidden one behind it, so it would be 1x
3x - 2(x + 1) = 2x - 7
Use the distributive property to multiply −2 by x+1.
3x−2x−2=2x−7
Combine 3x and −2x to get x
x−2=2x−7
Subtract 2x from both sides
x−2−2x=−7
Combine x and −2x to get −x
−x−2=−7
Add 2 to both sides
−x=−7+2
Add −7 and 2 to get −5
−x=−5
multiply both sides by -1
x=5

Answer:
A. √32y²/72x²= 32y/72x
Step-by-step explanation:
√32y²/72x²= 32²/72²
= 32/72.
B. √125m³/36m²
=4192.6/108
=38.8203.
C. √x²/y²-y²/x²
therefore, x²=1, y²=-1
that is, √1/-1 - -1/1= -1(-)-1=0.

Which statement best explains the relationship between
lines AB and CD?
-They are parallel because their slopes are equal.
-They are parallel because their slopes are negative
reciprocals.
-They are not parallel because their slopes are not
equal.
-They are not parallel because their slopes are
negative reciprocals.
Answer:
they are parallel because their slopes are equal
Answer:
They are parallel because their slopes are equal.
Step-by-step explanation:
Find the slope using the points indicated on each line
The slope of AB
m = rise/run = 6/8 = 3/4
The slope of CD
m = rise/run = 3/4
They are parallel because their slopes are equal.
What is the value of x in the equation
1/2 x - 3/4 = 3/8 - 5/8
Answer:
The value of x is 1
Step-by-step explanation:
1/2 x - 3/4 = 3/8 - 5/8 x
1/2 x + 5/8x = 3/8 + 3/4
9/8 x = 9/8
x = 1

Write two linear equations to represent a system to solve this, where X represents the smaller number and
y represents the larger number. Write the equations, but do not solve them.
Answer:
Step-by-step explanation:
2x + 8y = 19
5x + 7y = 15
Evaluate the following linear equation y = 7x - 2, when x = 3.
20 points
Answer:
y = 19
Step-by-step explanation:
y = 7x - 2
=> y = 7(3) - 2
=> y = 21 - 2
=> y = 19
Therefore, y = 19

A car's gas mileage is the distance it can go using 1 gallon of gas (measured in miles per gallon).
Based on the graph, what is this car's gas mileage? Explain.
Answer:
20 mpg
Step-by-step explanation:
Answer:
The car is traveling 20 miles per gallon.
Step-by-step explanation:
There are two ways you can solve this.
1) Since this is a graph of the car's gas mileage, all you have to do is look to find the miles for one gallon, which is plotted in this case. As you can see, for one, it is plotted halfway between 0 and 40, so that means the mile number would be 20. Looking at this, the car travels 20 miles per gallon.
2) You can also look at the point at the top that is clearly defined, and the point is (12, 240), 12 gallons used for 240 miles. To get the exact number of miles for one mile, you would divide 12 and 240 both by 12, which results in (1, 20). Since it is miles per gallon, the car gas mileage is 20 miles per gallon.
Hope this helped and have a great day!

In a sequence of four numbers, the difference between each number is 7.
The sum of the four numbers is 6.
What are the numbers in the sequence?
You must show all your working.
Answer:
Step-by-step explanation:
Let x be the lowest number of the four
x + (x + 7) + (x + 14) + (x + 21) = 6
4x + 42 = 6
4x = -36
x = -9
-9 + 7 = - 2
-9 + 14 = 5
-9 + 21 = 12

NoQuick Computing installed its previous generation of computer chip manufacturing equipment 3 years ago. Some of that older equipment will become unnecessary when the company goes into production of its new product. The obsolete equipment, which originally cost $40 million, has been depreciated straight-line over an assumed tax life of 5 years, but it can be sold now for $18 million. The firm’s tax rate is 35%. What is the after-tax cash flow from the sale of the equipment?
The company's after-tax cash flow is a measure of the company's cash
generation ability.
The after-tax cash flow from the sale of the equipment is $16.1 millionReasons:
The given parameter are;
Original cost of the equipment = $40 million
The type of depreciation = Straight line depreciation
Number of years of depreciation = 5 years
Current price at which it can be sold = $18 million
The tax rate of the firm = 35%
Required:
The after-tax cash flow from the sale of the equipment.
Solution:
The Cash Flow After Tax, CFAT, is given as follows;
CFAT = Net income + Amortization + Depreciation + Other non-Cash Cash Charges
The annual depreciation is given as follows;
[tex]Annual \ depreciation = \dfrac{\$40 \ million - \$18 \ million}{5 \ years} = \$4.4 \ million \ per \ year[/tex]
Selling the equipment gives;
The Earnings Before Tax (EBT) = $18 million
The Net Income = Income - Tax = $18 million - (35% × $18 million)
The Net Income = $11.7 million
Cash Flow After Tax CFAT = Net income + Depreciation
∴ CFAT = $11.7 million + $4.4 million = $16.1 million
The after-tax cash flow = $16.1 millionLearn more here:
