A. This gives us 3v + 15 = 3v - 4. This is no solutions because the slope is the same and the y-intercept is different.

A. Are the expressions 3(m−2) + 2(m−2) and 5(m−2) equivalent expressions?

B. In two or more complete sentences, justify your answer to A.

The answer is yes. If you solve both expressions it would be 5m-10.

**Answer: yes, this is because when you solve the first equation then your answer will be 5(m-2). You do this by distributing 3 to m & 2 (multiply), then you will distribute 2 to m & 2 (also multiply). **

**Step-by-step explanation:**

If anyone can figure the answer, please tell me. Anything would be helpful :)

Because of demand, concert tickets that normally sell for 89.99 each are marked up 20%, If Mark wishes to purchase 8 tickets, how much will he pay in total?

20 points will be given

Answer:$863.92

Step-by-step explanation:20% of 89.99 is 18

89.99x8=719.92

18×8=144

719.92+144=

863.92

**Answer:**

he will pay 864 dollars in total

**Step-by-step explanation:**

first we have to find 20% of 90 (i just rounded 89.99 to 90).

20% = 1/5, and 1/5 in decimal form is 0.20. (you can find the decimal value by multiplying the numerator and denominator by 10/10 and then simplifying it)

0.20 * 90 is 18, so we then add that to 90 making 108.

next, since Mark is buying 8 tickets, we multiply 108 by 8, giving us 864

**therefore, 864 is our final answer**

(PLEASE HELP) To feed 7 horses for 4 days, Mark needs 420 kg of grass. How many kilograms of grass does Mark need to feed 9 horses for 6 days?

**Answer:**

810kg is the answer

**Step-by-step explanation:**

Hope this helps:)

420 divided by 4 is 105 so each day 7 horses eat 105 kg of grass,

105 divided by 7 = 15 so each horse intakes 15 kg of grass per day

9x15=135

135x6 =810

105 divided by 7 = 15 so each horse intakes 15 kg of grass per day

9x15=135

135x6 =810

Sergio claims that StartFraction 20 Over 20 EndFraction = 1 percent. Which statement is true regarding his claim?

Answer: You dont give the statement. But 20/20 is 100% if that helps!

Step-by-step explanation:

Sam’s discount shoes is have a 40 percent off sale. A — use the percent ruler at right to find how much Lorna will save on her purchase of 80 dollar professional basketball shoes. B What will she pay for the shoes?

**Answer:**

A, 32

B, 48

**Step-by-step explanation:**

Since the discount is 40% off, she will save 40% of the 80 dollar shoes, which is 40% of 80 dollars. 40 * 80 = 3200, and 3200/100 = 32 dollars worth of savings. She will pay a total of 80 dollars minus the 32 dollar discount to get a total of 48 dollar payment.

**Answer:**

40% off that means her shoes will be 60% of the value so 80* 0.6 or 60% = $48 she will pay and 32 she will save

Solve for b.

b - 7 = -20

A. b = -27

B. b = -13

C. b = 13

D. b = 27

**Answer:**

B. b = -13

**Step-by-step explanation:**

b - 7 = -20

move variables and numbers to different sides of the equal sign by adding 7 to both sides

b - 7 + 7 = -20 + 7

b = -13

your answer would be -13 :) have a good day

**Answer: 12 h ; 45 m**

**Step-by-step explanation:**

***Important: **From what I can see in this image, this appears to be a test. If this is the case, please do not cheat. In any case, here is the explanation.

**What we know:**

**How to solve:**

By setting up an algebraic equation, we can solve this.

**Process:**

95/20 + 12/20x = 250/20

Subtract -95/20 -95/2012/20x= 155/20

Isolate x via division /(12/20) /(12/20)+Simplifyx= 12 11/20

Convert 12 h 33 m**Solution: 12 ; 45**

The **minimum **amount of time taken by the machine will be 12 **hours **and 55 **minutes**.

The allocation of weights to the important** variables **that produce the **calculation's **optimum is referred to as a direct **consequence**.

An **exceptional **machine is utilized at a building site to dig openings. An opening is dug to a profundity of 4.75 feet when the **machine **hits the rock. The advancement eases back to 3/5 feet each **hour **of digging. The profundity of the opening should be **no less **than 12 ¹/₂ feet before the day's over to **remain **on time.

Convert the **mixed** **fraction **number into a **decimal **number.

12 ¹/₂ feet = 12.5 feet

Let 'x' be the **time**. Then the equation is given as,

(3/5)x = 12.5 - 4.75

**Simplify **the equation, then we have

(3/5)x = 12.5 - 4.75

(3/5)x = 7.75

x = 12.9167

x = 12 + 0.9167 x 60

x = 12 hours and 55 minutes

The base measure of time taken by the **machine **will be 12 **hours **and 55 **minutes**.
