Point E is on line segment DF. Given DE = 2x, EF = 2x – 6, and
DF = 3x + 5, determine the numerical length of EF.
Answer: EF =
Answer:
EF is 16.
Step-by-step explanation:
So we know that Point E is somewhere on Line DF. In other words, DE plus EF must equal DF. In an equation, this is:
[tex]DF=DE+EF[/tex]
We are given that DE is 2x, EF is 2x-6, and DF is 3x+5. So, substitute:
[tex](3x+5)=(2x)+(2x-6)[/tex]
Now, solve for x.
On the right, combine like terms:
[tex]3x+5=4x-6[/tex]
Subtract 4x from both sides:
[tex]-x+5=-6[/tex]
Subtract 5 from both sides:
[tex]-x=-11[/tex]
Divide both sides by -1:
[tex]x=11[/tex]
Now that we know x is 11, substitute this back into the equation for EF to find EF.
[tex]EF=2x-6[/tex]
Substitute 11 for x:
[tex]EF=2(11)-6[/tex]
Multiply:
[tex]EF=22-6[/tex]
Subtract:
[tex]EF=16[/tex]
And we're done!
Frank makes x dollars per week. His dad makes 4 times as much money as him each week. Each week their income adds up to 1.000 dollars. How much does frank earn each week? How much does franks dad earn each week?
Answer:
Frank earns $200.
His dad earns $800.
Step-by-step explanation:
Giving the following information:
His dad makes 4 times as much money as him each week. Each week their income adds up to 1.000 dollars.
We know that:
x= Franks income
4x= Dads income
y= total income
y= x + 4x
1,000= 5x
1,000/5=x
200=x
Frank earns $200.
His dad earns $800.

Answer:
Peter walks at a rate of 13/4 miles per hour.
Step-by-step explanation:
Peter walks at a rate of 13/4 miles per hour because every hour, represented by x, he walks 3.25 hours or 13/4. y is the total miles he walked so if he walks two hours the y would equal 6.5 or 26/4 and the x would equal 2.
Solve the inequation (2x+3x)4 using distributive method.
Answer:
First, distribute the 4.
2x times 4 = 8x
3x times 4 = 12x
then add/ combine like terms.
8x + 12x = 20x
Step-by-step explanation:
Answer:
20x
Step-by-step explanation:
distribute the 4 to the 2x and 3x: 4 * 2x= 8x and 4 * 3x= 12x
then add the x's together: 8x+12x=20x
so the answer is 20x
1.5y-9.82=-9.37-10.1y-14.37 solve for y
Step-by-step explanation:
1.5y - 9.82 = -9.37 - 10.1y - 14.37
1.5y + 10.1y = 9.82 -9.37 - 14.37
11.6y = −13.92
y = (-13.92)/11.6
y = -1.2

What is the equation of a line with a slope of –2 that passes through the point (6, 8)?
Answer:
The answer is
y = - 2x + 20Step-by-step explanation:
To find the equation of the line given a point and slope we use the formula
[tex]y - y_{1} = m(x - x _{1})[/tex]
where
m is the slope
( x1 , y1) is the point
From the question
The point is (6, 8) and
slope - 2
The equation of the line is
[tex]y - 8 = - 2(x - 6) \\ y - 8 = - 2x + 12 \\ y = - 2x + 12 + 8[/tex]
We have the final answer as
y = - 2x + 20Hope this helps you

Do these two expressions represent equivalent expressions? Explain why or why not. 36 + 20 4(9 + 5)
Answer:
yes because 4 times 9 is equal to 36 and 4 times 5 is equal 20
Step-by-step explanation:
Yes, both the expressions ( 36 + 20 ) and 4 ( 9 + 5 ) are equivalent to each other.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
The given expressions are solved as:-
First expression,
36 + 20 = 56
Second expression,
4( 9 + 5 ) = 36 + 20
= 56
From the above calculations,
( 36 + 20 ) = 4 ( 9 + 5 )
Therefore, both the expressions ( 36 + 20 ) and 4 ( 9 + 5 ) are equivalent to each other.

one-half the cube of m subtracted by 4 *
Answer:
[tex]\frac{m^3}{2} - 4[/tex]
Step-by-step explanation:
Required
Determine an expression for the given statement
The expression can be rewritten as:
one-half * the cube of m subtracted by 4
Convert each statement to mathematical expressions:
One half = [tex]\frac{1}{2}[/tex]
The cube of m = [tex]m^3[/tex]
one-half * the cube of m = [tex]\frac{1}{2} * m^3[/tex]
At this stage, we have:
[tex]\frac{1}{2} * m^3[/tex] subtracted by 4
This gives:
[tex]\frac{1}{2} * m^3 - 4[/tex]
[tex]\frac{m^3}{2} - 4[/tex]
Hence, The corresponding expression is [tex]\frac{m^3}{2} - 4[/tex]
One-half the cube of m subtracted by 4 is [tex]0.5\sqrt[3]{m} -4[/tex]
Based on the information given, one-half the cube of m subtracted by 4 is expressed as:
[tex]0.5\sqrt[3]{m} -4[/tex]Note that the cube of m is expressed as [tex]\sqrt[3]{m}[/tex]The half of the cube of m will be given as [tex]0.5\sqrt[3]{m}[/tex]Subtracting 4 from the result will give the final expression as [tex]0.5\sqrt[3]{m} -4[/tex]

In a stationary store,pencils have one price and pens have another price.Two pencils and three pens cost 78 cents.However, 3 pencils and 2 pens cost 72 cents . How much does one pencil cost?
Answer:
12¢
Step-by-step explanation:
Let the unit price of a pencil be x and the unit price of a pen be y.
2x+3y=78¢
3x+2y=72¢
(2x)+3y=78¢
(3x)+2y=72¢
=2x=78¢-3y
=2x/2=78¢/2+3y/2
=x=36¢-1.5y
You then use the equation 3x+2y=72¢.
3(36¢-1.5y)+2y=72¢
=117¢-4.5y+2y=72¢
=117¢-72¢=4.5y-2y
=45¢=2.5y
=45¢/2.5=y
=18¢=y
So a pen costs 18¢.
You then use x=36¢-1.5y
x=36¢-1.5(18¢)
=x=36¢-27¢
=x=12¢
Therefore, a pencil costs 12¢.

Answer:
Square root 8 over three, (square root of 4)/2, and pi/3.
Step-by-step explanation:
First of all, square the radicals to make solving this easier. Squarer root 8 over three will become 8/9, and square root 4 over 2 will now become 4/4, which is 1. Pi/3 is greater than 1, so we can now order this from least to greatest. 8/9 is the least, 1 is the second greatest value, and pi/3 is the greatest value.
Answer: 8squared/3 4squared/2 Pi/3
Step-by-step explanation:
8 squared = 2.8... = 2.8/3 (least)
4 squared = 2 = 2/2 = 1 (second least)
Pi over 3 = 3.14159.../3 = 1 .14159/3 (greatest)

Answer:
x = 6
Step-by-step explanation:
Given AG bisects ∠ RAZ , then
∠ RAG = ∠ ZAG , that is
8x + 5 = 4x + 29 ( subtract 4x from both sides )
4x + 5 = 29 ( subtract 5 from both sides )
4x = 24 ( divide both sides by 4 )

The dimensions of a rectangular prism are length is 2 1/4 feet width is 1 foot and height is 1 1/4 feet and the length of the sides of a small cube are 1/4 foot each. How many small cubs can be packed in the rectangular prism.
Answer:
180
Step-by-step explanation:
2 1/4 ft = 9/4 ft, so is a length equivalent to 9 cubes.
1 ft = 4/4 ft, so is a length equivalent to 4 cubes.
1 1/4 ft = 5/4 ft, so is a length equivalent to 5 cubes.
Then the volume of the prism is ...
V = LWH
V = (9)(4)(5) = 180 . . . cubes
What is 90% of 81?
X
Answer:72.9
Step-by-step explanation:
Answer:
72.9
Step-by-step explanation:
Fractions method:
[tex]81*\frac{90}{100}[/tex] because 90/100 is the same thing as 90%
That gives us 7290/100, from 81*90/100
Simplify: =729/10 = 72.9
Decimals method:
81*9 = 729, add in decimal and that's 72.9
Cross-multiplication:
90 100
? 81
This is read as 90 to 100, (as a ratio) so how many to 81? To solve, cross-multiply - 81*90=7290, then divide by 100 to get 72.9.
This is my first answer , hope it helped!
