Answer:

32.8

Step-by-step explanation:

We are given the expression:

39/y +5y

We know that y is equal to 5. Therefore, we can substitute 5 in for every y.

39/5 + 5(5)

Solve from left to right according to PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction)

First, divide 39 by 5.

7.8+5(5)

Next, multiply 5 and 5

7.8+25

Finally, add 7.8 and 25

<em> $answer = 32.8 \\ solution \\ \frac{39}{y} + 5y \\ = \frac{39}{5} + 5 \times 5 \\ = \frac{39}{5} + 25 \\ = \frac{39 + 25 \times 5}{5} \\ = \frac{39 + 125}{5} \\ = \frac{164}{5} \\ = 32.8 \\ hope \: it \: helps$ </em>

Plz will mark as brainliest

Alenkasestr [34]

Answer:

Step-by-step explanation:

1/2 x (a+b) x h = area

1/2 x ( 40 + x ) x 50 = 1750

1/2 (40 + x )= 1750/50

20 + 1/2x = 35

1/2 x = 35 - 20

x = 15 x 2

= 30

I hope this is right :)

Conor runs at a constant rate, it takes 34 minutes to run 4 miles . Write the linear equation in two variables that represents t

Bad White [126]

Answer:

4x+y=34

Step-by-step explanation:

Linear equations can be written in 3 forms:

slope-intercept form

standard form

point-slope form

standard form's formula is ax+by=c,

now sub in 34 for c and 4 for a

4x+by=34

we can put in 1 for b since there is no other integers

4x+y=34

Watching the weather channel, you can see the probability of it raining tomorrow. drag the term to the corresponding probability

azamat

Answer:

Probability:

1. probability of rain < 1/2 -------- Unlikely

2. probability of rain = 0 -------- Impossible

3. probability of rain = 1 -------- Certain

4. probability of rain > 1/2 --------- Likely

Step-by-step explanation:

Given -

Terms:

• impossible

• likely

• unlikely

• certain

Probability:

1. probability of rain < 1/2

2. probability of rain = 0

3. probability of rain = 1

4. probability of rain > 1/2

To find - Watching the weather channel, you can see the probability of it raining tomorrow. drag the term to the corresponding probability of it raining tomorrow. drag the term to the corresponding probability of it raining tomorrow.

Proof -

Probability:

1. probability of rain < 1/2 -------- Unlikely

2. probability of rain = 0 -------- Impossible

3. probability of rain = 1 -------- Certain

4. probability of rain > 1/2 --------- Likely

Reason -

Probability is the chance that an event will occur. Weather predictions are based on probability.

The probability of an event occurring is represented by a ratio.

A ratio is a number that is between 0 and 1 and can include 0 and 1.

An event is impossible if it has a probability of 0.

Having 13 months in a year has the probability of 0.

An event is certain if it has the probability of 1.

The probability that the sun will rise tomorrow morning is 1
