Answer:

43.75

Step-by-step explanation:

Answer:

11/8 or 1 & 3/8

Step-by-step explanation:

5 & 2/8=21/4

3&7/8=31/8

21/4-31/8=11/8 or 1 & 3/8

Answer:

[tex]1\frac{3}{8}[/tex]

Step-by-step explanation:

Convert to improper fractions.

[tex]\frac{42}{8} -\frac{31}{8}[/tex]

Subtract.

[tex]\frac{11}{8} = 1\frac{3}{8}[/tex]

good luck, i hope this helps :)

The value of x would be 11.

Step-by-step explanation:

We can simply just isolate x in the equation to solve:

2x + 40 = 62

(Subtract 40 from both sides) 2x = 22

(Divide each side by 2) x = 11

Hope this helps! :)

============================================================

Explanation:

If we knew the value of x, we would use PEMDAS to evaluate 2x+40 to get some single number value. For instance, if x = 4, then 2x+40 becomes 2(4)+40 which evaluates to 48 when you use PEMDAS.

However, we don't know the value of x. To find x, we follow PEMDAS in reverse to undo everything happening to x.

Note the order in which stuff is happening to x

To undo this, we follow this process in reverse. So we need to undo the "add 40" part first, which was the last thing done. That means we'll subtract 40 from both sides

2x+40 = 62

2x+40-40 = 62-40

2x = 22

Then we undo the "multiply by 2" part. We'll divide both sides by 2

2x = 22

2x/2 = 22/2

x = 11

Let's check the answer.

2x+40 = 62

2(11)+40 = 62 ... x replaced with 11

22+40 = 62

62 = 62

Since we get the same thing on both sides, we get a true equation and this confirms we have the correct x value.

Answer:

7x - 18

Step-by-step explanation:

x multiplied by seven = 7x

eighteen subtracted from product (7x) = -18

7x - 18

Answer:

7x-18

Step-by-step explanation:

the ans is 7x-18 because x is multiplied to 7 so its 7x

Answer:

all real numbers greater than but not equal to 0

Answer:

The cost of the mug is of $6.50.

Step-by-step explanation:

The cost of the mug and r refills is given by the following equation:

[tex]C(r) = 2.3r + 6.5[/tex]

Cost of the mug:

The cost of the mug is found when no refills are bought, that is, C when [tex]r = 0[/tex], which is [tex]C(0)[/tex]

[tex]C(0) = 2.3*0 + 6.5 = 6.5[/tex]

The cost of the mug is of $6.50.

Answer:

The smaller number is 8

The bigger number is 11

Step-by-step explanation:

let the first number be A

let the second number be B

A + 2B = 30..... equation 1

A + B = 19...... equation 2

Subtract equation 2 from 1.

A + 2B = 30

- A + B = 19

-------------------

0 + B = 11

B = 11

Substitute B = 11 into equation 2

A + B = 19

A + 11 = 19

collect like terms

A = 19-11

A = 8.

A= 8 and B = 11

Answer:

10.26 bags

Step-by-step explanation:

Area of circle :

A = πr²

radius, r = 7ft

A = π * 7²

A = π * 49

A = 153.93804 ft²

Since a bag covers 15 ft² ;

Number of bags needed will be :

Area / number of square feet per bag

153.93804 ft² / 15 ft²

= 10.262536 bags

= 10.26 bags

Answer:

10.21

this is the correct answer because 10.21 is right

Answer:

The height of the taller tree is 7.5 feet.

Step-by-step explanation:

I am going to say that:

The height of the shorter tree is x.

The height of the taller tree is y.

The height of shorter tree is 3/5 of the height of the taller tree.

This means that [tex]x = \frac{3y}{5}[/tex]

If the height of the shorter tree is 4 1/2 feet tall, what is the height, in feet, of the taller tree? ​

This means that [tex]x = 4 + \frac{1}{2} = \frac{8+1}{2} = \frac{9}{2}[/tex]

We want to find y.

[tex]x = \frac{3y}{5}[/tex]

[tex]\frac{9}{2} = \frac{3y}{5}[/tex]

[tex]6y = 45[/tex]

[tex]y = \frac{45}{6}[/tex]

[tex]y = 7.5[/tex]

The height of the taller tree is 7.5 feet.

Answer: b) $60.56 per year of age

Step-by-step explanation: If the scatterplot of two variables shows a line and the correlation between them is strong, we can calculate a regression line.

Regression line is a line graph that best fits the data. Like any other line, its formula is given by

y = mx + b

with

m being the slope

b the y-intercept

The slope of the line, correlation and standard deviations of the two variables have the following relationship:

[tex]m=r\frac{S_{y}}{S_{x}}[/tex]

where

r is correlation

[tex]S_{y}[/tex] is standard deviation for the y data

[tex]S_{x}[/tex] is standard deviation for the x data

For our problem:

r = 0.34

[tex]S_{y}=[/tex] 2850

[tex]S_{x}=[/tex] 16

Calculating

[tex]m=0.34(\frac{2850}{16})[/tex]

m = 60.56

Slope for the regression line of annual income per year of age is 60.56.

Step-by-step explanation:

5(m – 8) - 4(m – 7)

5m-40-4m+28

m -12

Answer:

5(m - 8) - 4(m - 7)

= 5m - 40 - 4m +28

= m - 12

m = 12

I did not understand Q3 and I could not, but I understood Q2

The answer is Q2: 12 liters

Step-by-step explanation:

First car.

0.2 gallons used for 7 miles.

Distance drive on 1 gallon of gas [tex]=\dfrac{7}{0.2}=35\ \text{miles}[/tex]

Second car.

0.5 gallons used for 12 miles.

Distance drive on 1 gallon of gas [tex]=\dfrac{12}{0.5}=24\ \text{miles}[/tex]

Third car.

0.9 gallons used for 25 miles.

Distance drive on 1 gallon of gas [tex]=\dfrac{25}{0.9}=27.8\ \text{miles}[/tex]

So, the first car traveled fast while the second car traveled least. Hence, the sequence is first car > third car > second car.

Answer:

y = 3x + 5 option A

Step-by-step explanation:

For 2 lines that are parallel with slopes m1 and m2, the slopes are equal. Hence

m1 = m2

Given the line y = 3x - 5 Comparing with the general equation of a line

y = mx + c where m is the slope of the line

m = 3

hence m1 = m2 = m = 3

For the line that passes through the given point (2,11) Using

y - y1 = m (x - x1)

y - 11 = 3(x - 2)

y - 11 = 3x - 6

Add 11 to both sides

y = 3x - 6 + 11

y = 3x + 5

Answer:

the answer is m equals 3 over 5

Answer:

x = 2

Step-by-step explanation:

distance = -6-(-2) and 4-2

-6+2 and 2

-4 and 2 is distance

Answer:

[tex]d = \sqrt{(x_{2}-x_{1})^{2} +(y_{2}-y_{1})^{2} }[/tex]

d = √(4 - (-2))² + (2 - (-6))²

d = √36 + 64

d = 10
