which expression below me is equivalent to -3x+5(x+2)?

A.2x+2

B.-x+2

C.2x+10

D.-8x+10

Answers

Answer 1

Answer:

C)

Step-by-step explanation:

First use distributive property: a(b +c) =a*b +a*c

-3x + 5(x +2) = -3x + 5*x +5*2

                   = -3x + 5x + 10          {Combine like terms}

                  = 2x + 10

(-3x) and 5x are like terms

Answer:

n = 7.2

Step-by-step explanation:

I just divided both sides by 5.

5n (÷ 5) = 36 (÷ 5)

n = 7.2 or 7 [tex]\frac{1}{5}[/tex]

You can choose between using the decimal or the fraction.

Answer:

n=7.2

Step-by-step explanation:

=> 5n=36

=> 5n/5 =36/5 [Divide by 5 on both the sides]

=> n=7.2

Ken is cutting wooden pieces that each measure 2/3 ft long. If ken is cutting from a piece that measures 9 1/3 ft, how many pieces can ken cut

Answers

Answer:

14 pieces

Step-by-step explanation:

Given that the total length available is 9 1/3 ft long and the pieces being cut is 2/3 ft long, the number of pieces that may be cut may be computed by dividing the total length by the length of each piece

= 9 1/3 / 2/3

= 28/3 * 3/2

= 14 pieces

A plant is already 54 centimeters tall, and it will grow one centimeter every month. The plant's height, H (in centimeters), after M months is given by the following.
What is the plant's height after 13 months?

Answers

Answer:

67 cm

Step-by-step explanation:

We are given the initial height of the plant let's call it H.

H = 54 cm. This is the original height of the plant at M(months) = 0.

We are given that it grows at 1 cm/month. This is the rate of growth.

Rate = 1

Time (M) is given in Months.

So when M = 0, H = 54

Let's say M = 1, That is one month has passed. In this time the plant's height would have increased by 1 cm. So our plant's height would be H = 54+1 = 55 cm.

When Two months have passed our plant's height would be H = 54 + 2 = 56 cm , since every month our plant gains 1 cm in Height, we can make a fuction for this.

H = 1M + 54.

Now we just plug in 13 for M, to get 13 months.

H = 13 + 54

H = 67 cm

So our plant would be 67 cm in height after 13 months.

You want to rent a television Company A charges $50 per week plus a one-time fee of $15. Company B charges 130 per week plus a one time fee of $55. After
how many wears are the total costs the same at the companies?

Answers

Company A: y = 50x + 15
Company B: y = 130x + 55

Set the equations equal to each other and solve for x (number of weeks).
50x + 15 = 130x + 55

Subtract 50x from both sides:
15 = 80x + 55

Subtract 55 from both sides:
-40 = 80x

Did you have a typo? The companies will never have the same cost because company B costs so much more and weeks cannot be negative.

3(5p - 1) - 4(3p - 7)
Also please explain it as well

Answers

Answer:

3p + 25

Step-by-step explanation:

Let's start with the original expression:

3(5p – 1) – 4(3p – 7)

We need to distribute each constant to the binomial they are multiplying, and when we do that, we get:

15p – 3 – 12p + 28

Why did the 28 turn out positive? We multiplied two negative numbers together, –4 and –7 , and multiplying two negatives always gives us a positive product.

Now, let's rewrite the expression to group like terms together:

15p – 3 – 12p + 28  — marked like terms, constants bold, variables underlined

15p – 12p + 28 – 3  — rewrote the expression to group like terms

Finally, we combine each set of like terms together to get our final answer:

3p + 25  — simplifying

Hope this helps you understand the concept! Have a great day!

3p+25 you just have to distribute and then collect like terms
