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]

Answer:

$0.45x

Step-by-step explanation:

Fred earns dollars. Let Fred earns $x.

Chad earns 45% more than Fred.

We need to find the expression for Chad.

Chad amount = 45% of x

[tex]=\dfrac{45}{100}x\\\\=0.45x[/tex]

So, Chad earns $0.45x.

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.

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

Answer: =2/15

Step-by-step explanation: Hope this help :D

Answer:

2/15

Step-by-step explanation:

4/5 - 2/3

Step 1: Find a common denominator. 5 and 3 don't share any factors other than 1, so multiply them to get 15.

12/15 - 10/15

(12 - 10)/15

Step 2: Subtract 10 from 12 to get 2.

2/15

4/5 - 2/3 simplified is 2/15.

Step-by-step explanation:

The length of side b in triangle 2 is 36.

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.

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.

Answer:

 [tex]a_n=a+(n-1)d[/tex]

Step-by-step explanation:

The given sequence is 22, 20, 18, ...

We need to find the explicit formula for an.

First term is 22

Second term = 20

Third term = 18

We can write the formula as :

[tex]a_n=a+(n-1)d[/tex]

Where

a is 22

d is common difference = 20-22 = -2

Forth term will be :

[tex]a_4=22+(4-1)(-2)\\\\=22-6\\\\=16[/tex]

Hence, the formula is [tex]a_n=a+(n-1)d[/tex].

Answer:

x=40

Step-by-step explanation:

The measure of the angle <RTS is half the difference of the measures of the intercepted arcs (mRS and mQP).

<RTS=(1/2)(mQP-mRS)

(x/2)=(1/2)((x+70)-(x+30))

x=x+70-x-30

x=40

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.
