Answer:
[tex]\sf D.\;\;x=2[/tex]
Step-by-step explanation:
[tex]\sf 3x + 2 = 7x - 6[/tex]
Subtract 2 from both sides:-
[tex]\sf 3x+2-2=7x-6-2[/tex]
Simplify:-
[tex]\sf 3x=7x-8[/tex]
Subtract 7x from both sides:-
[tex]\sf 3x-7x=7x-8-7x[/tex]
Simplify:-
[tex]\sf -4x=-8[/tex]
Divide both sides by -4:-
[tex]\sf \dfrac{-4x}{-4}=\dfrac{-8}{-4}[/tex]
Simplify:-
[tex]\sf x=2[/tex]

The total number of ski trails based on the information about the fraction is 12 ski trails.
How to calculate the fraction?The difference in length between the longest ski trail and the shortest ski trail will be:
= 3 1/8 - 2 1/4
= 3 1/8 - 2 2/8
= 7/8 miles
The total length of the ski trials that are 2 7/8 miles long will be:
= 3 × (2 7/8)
= 3 × 23/8
= 69/8
= 8 5/8 miles
The sum of the shortest and longest trail will be:
= 3 1/8 + 2 1/4
= 3 1/8 + 2 2/8
= 5 3/8
Lastly, the longest ski trail isn't more than three times the shortest trail. Therefore, Eli is correct.

Answer:
$800 in a week
Step-by-step explanation:
to find how much she had after giving it to her mother we can use the equation 240 / 75%
240 / 75% = 320
then you must find how much she had before she gave part of her wage to her mother
320 / 40% = 800
she earns $800 in a week
Answer:
800$

The populations of two cities after t years can be modeled by -150t+50,000 and 50t+75,000. . What is the difference in the populations of the cities when t=4
Answer:
25,800
Step-by-step explanation:
-150(4) + 50,000 = 49,400
50(4) + 75,000 = 75,200
75,200 - 49, 400 = 25,800

Answer:
I believe it would be 4.
Step-by-step explanation:
If you are rounding it to the nearest whole number, you would want to take a look at the number next to it.
4 or less, let it rest (do not bump up the number)
5 or more, raise the score (bump the number higher by one)
Thus, the answer would be 4!

What is the value of x given the following image?
Answer:
27
Step-by-step explanation:
CDE is a right angle so the sum of CDF and FDE is equal to 90
2x + x + 9 = 90 add like terms
3x + 9 = 90 subtract 9 from both sides
3x = 81 divide both sides by 3
x = 27
Peter made a square pin for his pet guinea pig to roam in. One side was 18.2 cm. What is the area of the pin?
A. 331.24 cm
B. 321.24 cm
C. 74.8 cm
D. 72.8 cm
Hi!
Answer:
A) 331.24
Step-by-step explanation:
To find the area, you need to multiply LxW, (Length x Width) and in this case, since it's a square, the sides are equal. Each side is 18.2 cm, so all we have to do is multiply 18.2 by 18.2, and then we get 331.24, so your answer is option A.

What is the measure of angle 2 if angle 1 is (5x - 2) and angle 2 is (2x)?
Answer:
52 degrees
Step-by-step explanation:
We're given:
Angle 1 = 5x-2Angle 2 = 2xThe sum of the two angles is 180 degrees, because they construct a straight edge together. A straight line has an angle measure of 180 degrees.
Knowing this, we can form the following equation and solve for x:
[tex]5x-2+2x=180\\7x-2=180\\7x=182\\x=26[/tex]
Therefore, x is 26. Find 2x to find the measure of Angle 2:
[tex]2*26=52[/tex]
Therefore, Angle 2 has a measure of 52 degrees.
Answer:
52
Step-by-step explanation:
Angle 1 and angle 2 are on a straight line so their measure add up to 180 and they are supplementary
m<1 + m<2 = 180
5x - 2 + 2x = 180 add like terms
7x - 2 = 180 add 2 to both sides
7x = 182 divide both sides by 7
x = 26
To find the measure of angle 2 replace x with the value we found
m<2 = 2x
2*26 = 52
Find the length of the missing side in the figure below. a = _______ cm.
a right triangle with short side labelled a, long side labeled 4.7 cm and hypotenuse labelled 7.1 cm. PLEEZE! IM DESPERATE!
Answer:
[tex] \frac{2 \sqrt{177} }{5} [/tex]
or
5.32cm correct to 2 decimal places
Step-by-step explanation:
This is a right angled triangle from what I know so we have to apply pythagoras theorem.
[tex] {7.1}^{2} = {a}^{2} + {4.7}^{2} [/tex]
we need to rearrange this to find a²
[tex] {a}^{2} = {7.1}^{2} - {4.7}^{2} [/tex]
[tex]a = \sqrt{ \frac{708}{25} } [/tex]
This can either be written as a fraction or decimal.
[tex]a = \frac{2 \sqrt{177} }{5} [/tex]
OR
[tex]a = 5.32[/tex]
correct to 2 decimal places
