solve for x then, find m < FDG and m <GOF.
Answers
Answer:
choice 4) x = 27, ∠FDG = 62°, ∠GOF = 118°
Step-by-step explanation:
2x + 8 + 4x + 10 = 180°
6x + 18 = 180
6x = 162
x = 27
∠FDG = 2(27) + 8 = 62°
∠GOF = 4(27) + 10 = 118°
Robert bought a pair of shoes that was on sale for 30% off
the original price of $79.95. Which is closest to the sale
price of the pair of shoes?
Answers
Answer:
The sale price of the shoes is $55.96
Step-by-step explanation:
1: 30% of $79.95 is 23.985.
Which would round to $23.99.
Then subtract 23.99 from 79.95.
79.95-23.99= 55.96

Traveon is walking dogs for his neighbors, to make money. This week, he walked Mr. Jackson's dog 3.5 times farther than he walk Ms. Evans' dog. If the total distance that he walked both dogs is 17.5 miles, how far did he walk Ms. Evans' dog? *
Answers
Answer:
He walked Ms. Evans' dog 3.89 miles.
Step-by-step explanation:
From the information provided, you know that the total distance that he walked both dogs is 17.5 miles, which can be expressed as:
x+y=17.5, where:
x is the distance he walked Mr. Jackson's dog
y is the distance he walked Ms. Evans' dog
Also, the statement indicates that he walked Mr. Jackson's dog 3.5 times farther than he walk Ms. Evans' dog and you can write the following equation:
x=3.5y
Now, you can replace x=3.5y in the first formula and solve for y to find how far he walked Ms. Evans' dog:
3.5y+y=17.5
4.5y=17.5
y=17.5/4.5
y=3.89
According to this, the answer is that he walked Ms. Evans' dog 3.89 miles.

Answers
Answer:
x = 20
Step-by-step explanation:
The sum of the two angles is 90 degrees
x+3x+10 = 90
Combine like terms
4x+10 = 90
Subtract 10 from each side
4x+10-10 = 90-10
4x= 80
Divide each side by 4
4x/4 = 80/4
x = 20
Answer:
x = 20
Step-by-step explanation:
x and 3x + 10 form a right angle, then
x + 3x + 10 = 90
4x + 10 = 90 ( subtract 10 from both sides )
4x = 80 ( divide both sides by 4 )
x = 20

Answers
Answer:
4
Step-by-step explanation:
I saw karma so i came as fast as I could- welp anyways
Lets test the first equation and coordinate #1 first, 3x-2y=12, and (10,9).
Here we can substitute x as 10 and y as 9, and solve the equation to see if 3(10)-2(9) equals 12 or not.
30-18=12, yep
now lets test the second coordinate, (0, -6). Substitute x as 0 and y as -6, and solve the equation.
3(0)-2(-6)=12
0+12=12, yep
So I definitely works
For II, lets do the same thing
(10, 9) -- 9=3/2*10-6
9=15-6, works
(0, -6) — -6= 3/2*0-6
-6=0-6, also works
So uh therefore I and II both work you see what I mean-
i apologize in advance if i made you more confused than you already are-

Daniel expanded the expression as shown -3(-8x-4y+3/4)=10x-8y-1 1/4 what areas did he make like three options
Answers
Question
Daniel expanded the expression as shown. What errors did he make? Select three options.
[tex]-2(-8x-4y+3/4)=-10x-8y-1 \frac{1}{4}[/tex]
A. The first term should be positive.
B. The second term should be positive.
C. The last term should be -1 1/2, not -1 1/4.
D. He divided -8 by -2 instead of multiplying -8 by -2.
E. He did not simplify the expression completely.
Answer:
Daniel's errors are (a), (b) and (c)
Step-by-step explanation:
To do this, we only need to solve the expression on the left.
So, we have:
[tex]-2(-8x-4y+3/4)=[/tex]
Open bracket
[tex]-2(-8x-4y+3/4)=-2 * -8x -2 * -4y - 2 * 3/4[/tex]
[tex]-2(-8x-4y+3/4)=16x + 8y - \frac{2 * 3}{4}[/tex]
[tex]-2(-8x-4y+3/4)=16x + 8y - \frac{6}{4}[/tex]
[tex]-2(-8x-4y+3/4)=16x + 8y - 1\frac{1}{2}[/tex]
From the expression, we can see that:
The first term is positiveThe second is also positiveAnd the third term is[tex]- 1\frac{1}{2}[/tex]So, Daniel's errors are (a), (b) and (c)
Two angles are vertical if one is 5x - 15 and the second angle is 3x + 1, what is the value of x
What is the measure of each angle
Answers
Answer:
Step-by-step explanation:
If they are vertical angles, they are opposite to each other where two lines intersect. Vertical angles are equal to each other so
5x-15=3x+1
2x-15=1
2x=16
x=8 degrees.
The angles are
a=5x-15, and x=8 so
a=5(8)-15
a=40-15
a=25 degrees.
