Answer:
Given:
-4x - 2y = -2 x - 2y = 9Subtracting:
-4x - 2y - (x - 2y) = -2 - 9-4x - 2y - x + 2y = - 11-5x = -115x = 11x = 11/5x = 2.2You can now find y:
2.2 - 2y = 92y = 2.2 - 92y = - 6.8y = -6.8/2y = -3.4Solution (2.2, -3.4)

Answer:
[tex]\frac{4x}{x-2}+\frac{7}{x-2}[/tex]
Step-by-step explanation:
The general rule for add or subtracting fractions is that the fractions must have a common denominator, meaning that the value under the fraction bar must be the same. This rule is also applicable for algebraic fractions.
Therefore, when the question asks "Which of the following can be added without altering any of the fractions?", one should be looking for two fractions with a common denominator. Thus the answer would be the first option, which is the following;
[tex]\frac{4x}{x-2}+\frac{7}{x-2}[/tex]
Jade and Henry work for a company that sells buckets of popcorn. The company wants to have a special offer.
Here is Jade's idea for the special offer.
Put 20% more popcorn into each bucket and do not change the price.
Here is Henry's idea for the special offer.
Reduce the price and do not change the amount of popcorn in each bucket.
Henry wants his idea to give the same value for money as Jade's idea.
By what percentage, to the nearest whole number, does Henry need to reduce the price?
Answer:
17%
Step-by-step explanation:
17%
Step-by-step explanation:
Jade:
p-price
so 100%+20%=120% for the amount of cereal
Find 100%
120%=p
divide by 6
20%=p/6
times by 5
100% = 5p/6
Henry:
5p/6=83% Its the same amount of cereal but for 83% of the price
so 100-83=17%
which is the reduction
Triangle 2 is a scale drawing of Triangle 1.
Based on the information in the diagram, what is the length of side b?
Answer:
36 would be the answer
Step-by-step explanation:
The length of side b in triangle 2 is 36.
What are similar triangles?Two triangles are similar if they have the same corresponding angles and their corresponding sides are in equal ratios.
Given that, there are two triangles, triangle 2 is a scale drawing of triangle 1.
Therefore, Δ 1~Δ 2,
According to the definition of similar triangles,
6/27 = 10/45 = 8/b
Therefore,
8/b = 6/27
8/b = 2/9
b = 36
Hence, the length of side b in triangle 2 is 36.

Put the word “aware” before or after your answer if your gonna send a link. I would like to know if they are bots. (99% sure they are)
Answer:
B (range)
Step-by-step explanation:
The IQR would actually increase, because the Q1, Q2, and Q3 would get most likely larger. (Or possibly stay the same).
The median would most likely increase, possibly stay the same.
The maximu would stay the same.
The range would decrease, because right now it’s 13, so without the outlier, the minimum value would be closer to the rest of the data.

Alvin is 7 years younger than Elgas. The sum of their ages is 63. What is Elgas age?
Answer:
Elgas is 35.
Step-by-step explanation:
Let's set up an equation.
Alvin is 7 years younger than Elgas.
A = E - 7
The sum of their ages is 63.
A + E = 63
Let's use substitution.
Plug in the first equation of A into the second equation.
A + E = 63
(E - 7) + E = 63
Combine like terms.
2E - 7 = 63
Add 7 to both sides.
2E = 70
Divide both sides by 2.
E = 35
Elgas is 35.
Hope this helps!

(12 - 10)/15
Step 2: Subtract 10 from 12 to get 2.

If X = 9 units, Y = 7 units, Z = 18 units, and h = 8 units, what is the surface area of the triangular prism shown above?
Answer: 506 square units (answer choice B)
Step-by-step explanation:
The formula for the surface area of a triangular prism is:
SA = bh + 2ls + lb,
where b is the base, h is the height, l is the length, and s is the side of the triangle.
In this case, the base is 7 (Y), the height is 8 (h), the length is 18 (Z), and the side of the triangle is 9 (X).
So, by subsituition, we have:
SA = (7)(8) + 2(18)(9) + (18)(7)
SA = 56 + 324 + 126
SA = 506
The surface area is 506 square units.
Hope this helps! :)
