Answer:Solve x=−5−y;2+y=−x+3

I will solve your system by substitution.

x=−y−5;y+2=−x+3

Step: Solvex=−y−5for x:

Step: Substitute−y−5forxiny+2=−x+3:

y+2=−x+3

y+2=−(−y−5)+3

y+2=y+8(Simplify both sides of the equation)

y+2+−y=y+8+−y(Add -y to both sides)

2=8

2+−2=8+−2(Add -2 to both sides)

0=6

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.

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

Answer: A Patricia can type 35 more words per minute than George

Step-by-step explanation:

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!

Answer:

A

Step-by-step explanation:

The probability that a random customer will not rent a drama is 4/5. Option B is correct.

Probability can be defined as the ratio of favorable outcomes to the total number of events.

here,
Total number of rented DVDs = 25 + 36 + 52 + 12 = 125
Number of Drama movies = 25

The probability that a random customer will rent a drama.
P(D) = 25 / 125 = 1/5

Now,
The probability that a random customer will not rent a drama,
P(D)' = 1 - P(D)
       = 1 - 1/5 = 4/5

Thus, the probability that a random customer will not rent a drama is 4/5. Option B is correct.

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
