What is the solution to the equation 13.7y – 10.6 = 6.2y + 19.4

Answers

Answer: hope this helps :)))

y=4

Step-by-step explanation:

Step 1: Subtract 6.2y from both sides.

13.7y−10.6−6.2y=6.2y+19.4−6.2y

7.5y−10.6=19.4

Step 2: Add 10.6 to both sides.

7.5y−10.6+10.6=19.4+10.6

7.5y=30

Step 3: Divide both sides by 7.5.

7.5y/7.5 = 30/7.5

y=4

Willie left the mall and traveled toward the town hall at an average speed of 40 km/h. Gabriella left two hours later and traveled in the opposite direction with an average speed of 70 km/h. Find the number of hours Gabriella needs to travel before they are 410 km apart.

Answers

Answer:

Gabriella need to 2.45 hours of travelling to be 410km apart from Willie.

Step-by-step explanation:

In order to make them 410km apart and the time included in it is to be found

we proceed as

Willie left the mall earlier and Gabriella left two hours before

so willie has travelled for 2 hours while Gabriella was still at the initial point

with this logic we find the hours Gabriella needs as follows

              Willie               Gabriella

              ←←←←←←←←  →→→→→→→→→→

                40km/h            70km/h      

                 X hours             X+2 hours

40*x+70(x+2) = 410

40x+70x + 140=410

110x=270

x=270/110

x= 2.45hrs

0 Ç. f(x) = 7 + 5x
O D. f(x) = 12 + 5x

Answers

Answer:C. f(x)=7+5x

Step-by-step explanation:

12=5(1)+n

12=5+b

-b+12=5

-b=5-12

5-12=7

-b=7

f(x)=7+5x

I know this because I just answered this question and got it right

The equation of the function is f(x) = 7 + 5x option (C) f(x) = 7 + 5x is correct.

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that:

The table is given,

From the data given in the table:

12 = 5(1)+n

12 = 5+b

b = 7

The function would be:

f(x) = 7 + 5x

Thus, the equation of the function is f(x) = 7 + 5x option (C) f(x) = 7 + 5x is correct.

Answers

Answer:

Slope is a line on a graph, you find slope with the m=yx+b equation. Y intercept is the point that the line crosses the y axis at, it is represented by b. X and Y in the equation are your coordinates. You graph it by starting at your y-intercept and going up in a straight line following the slope calculated.

Mr. Mohr wants to build a rectangular patio using concrete tiles that are 12 square inches. The patio will measure 13.5 feet by 43 feet. What is the area of the patio? How many concrete tiles will he need to complete the patio?

Answers

Answer: He will need 49 tiles.

Step-by-step explanation:

Given: The patio will measure 13.5 feet by 43 feet.

Area of patio = 13.5 feet x 43 feet   [Area = length x width]

= 580.5 sq. feet

Since area of each concrete tile = 12 sq. inch

Number of concrete tiles required to cover patio = (Area of patio) ÷ (area of each concrete tile)

= 580.5 ÷  12

= 48.375 sq. inch ≈49

Hence, he will need 49 tiles.

Answer:

49 tiles

Step-by-step explanation:

Answer: He will need 49 tiles.

Step-by-step explanation:

Given: The patio will measure 13.5 feet by 43 feet.

Area of patio = 13.5 feet x 43 feet [Area = length x width]

= 580.5 sq. feet

Since area of each concrete tile = 12 sq. inch

Number of concrete tiles required to cover patio = (Area of patio) ÷ (area of each concrete tile)

= 580.5 ÷ 12

= 48.375 sq. inch ≈49

Hence, he will need 49 tiles.

If x^2+x =3^2/3+3^-2/3 then prove that 3x^3+9x-8=0

Answers

x^2 + 2 = 3^2/3 + 3^-2/3

x^2 = 3^2/3 + 3^-2/3 - 2

x = √(3^2/3 + 3^-2/3 - 2)

x = 0.748888296

Substitute for x in 3x^3 + 9x - 8:

3( 0.748888296)^3 + 9( 0.748888296) - 8 = 0.

So it is proved.

Ruby misses 10% of the free throws she attempts in a season. How many total free throws did she attempt if she missed 70?

Answers

Answer:

700

Step-by-step explanation:

70x10 = 700

The total number of free throws she attempted is 700.

What is a percentage?

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Missed free throws = 10%

Total free throws = 100%

10% = 70

Multiply 10 on both sides.

100% = 700

Thus,

Total free throws are 700.

For some reason, in our history class, there are 14 boys than there are girls. If a total of 32 students are in the class, how many boys and how many girls are there?

Answers

Answer:

There are 23 boys and 9 girls in the class

Step-by-step explanation:

The given information is that the number of boys = 14 + The number of girls

The total number of boys and girls = 32

Let the number of girls = x

Therefore, we have;

The number of boys = 14 + x

The total number of boys and girls = 32 = The number of boys + The number of boys

The number of boys + The number of boys = 14 + x + x = 14 + 2·x

∴ The number of boys + The number of boys = 32 = 14 + 2·x

14 + 2·x = 32

2·x = 32 - 14 = 18

2·x = 18

x = 18/2 = 9

x = 9

Therefore, the number of boys is 14 + x = 14 + 9 = 23 boys

The number of boys = 23 boys

The number of girls = x = 9 girls

the number of boys = 23 boys

The number of girls = x = 9 girls

The number of girls = 9 girls

Therefore, there are 23 boys and 9 girls in the class.
