Answer:7.5 apples

Step-by-step explanation:

Let the number of mangoes be represented by m

Max has 5 more Apples than Mangos.

Therefore apples = m + 5

Max has four times as many Apples as Peaches. Therefore, peaches = 4(m+5) = 4m + 20

Mangoes = m

Apples = m+5

Peaches = 4m+20

Mangoes + Apples + Peaches = 40

m + m+5 + 4m+ 20 = 40

6m+25 = 40

6m = 40 - 25

6m = 15

m = 15/6

m = 2.5

Apples = m+5 = 2.5 + 5 = 7.5

Max has 7.5 apples

Answer:

1) y= 1x +1

2) -2/5

Step-by-step explanation:

5 + 1/ 4 + 2 = slope of 1

y-5 = 1(x-4) solve for y

y = 1x + 1

Answer: b=-9

Step-by-step explanation:

To find the y-intercept of the line, we can use the points given to make an equation. To find the slope, you use the formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex].

[tex]m=\frac{3-(-6)}{4-1} =\frac{9}{3} =3[/tex]

Now that we know the slope, we can fill in what we know and solve for y-intercept.

y=3x+b

We can plug in any point to solve for y-intercept.

3=3(4)+b                [multiply]

3=12+b                   [subtract both sides by 12]

b=-9

Now, we know that the y-intercept is b=-9.

Answer:

Step-by-step explanation:

f(x)=x² - 2x + 7

To find f(-3) substitute the value of x that's - 3 into f(x). That is for every x in f (x) replace it with - 3

We have

f(-3) = (-3)² - 2(-3) + 7

= 9 + 6 + 7

We have the final answer as

f(-3) = 22

Answer:

4.30m/hr

Step-by-step explanation:

2 feet/8.5 mins is 0.235294118 feet per minute, which is 4.3030553875397 metres per hour, which to 2 s.f. is 4.30

In meters per hour the speed is 470 meters per hour.

We have an object moving at a speed of 2 feet every 8.5 minutes.

We have to express this speed in meters per hour.

1 feet = 3.29 meters

1 hour = 60 minutes → 1 minute = [tex]\frac{1}{60}[/tex] hour = 0.017 hr

According to question - We have :

Speed = 2 feet in 8.5 minutes

We know -

1 feet = 3.29 meters

2 feet = 2 x 3.29 = 6.58 meters

and

1 minute = 0.017 hr

8.5 minutes = 8.5 x 0.017 = 0.14 hr

Now -

In 0.014 hr, distance covered = 6.58 meters

In 1 hr, distance covered will be - [tex]\frac{6.58}{0.014}[/tex] = 470 meters/hour

Hence, in meters per hour the speed is 470 meters per hour.

Answer:

12

Step-by-step explanation:

3x - 12 = 24

Add 12 to both sides to make 3x the subject of the equation.

3x - 12 (+12) = 24 (+12)

3x - 0 = 36

3x = 36

Divide both sides by 3.

3x/3 = 36/3

x = 12

Please give brainliest, rate 5 stars, and thank. Thank you

The required solution to the given equation 3x -12 = 24 is x = 12.

Algebraic equations are mathematical statements with a minimum of two terms containing variables or numbers that are equal.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

The given equation is given in the question

⇒ 3x - 12 = 24

Add 12 to both sides of the above equation

⇒ 3x - 12 (+12) = 24 (+12)

⇒ 3x - 0 = 36

Apply the subtraction operation,

⇒ 3x = 36

Divide both sides by 3.

⇒ 3x/3 = 36/3

⇒ x = 12

Therefore, the required solution to the given equation 3x -12 = 24 is x = 12.

Answer:

The answer to your question is 8.666666666666.

The total numerical length of the segment JL is 6 units.

Given that,
Point K is online segment JL.
JK = 5x + 7,
JL = 2x + 8, and KL= 4
To determine the numerical length of JL.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
For point K on the line segment JL,
JL = JK + KL
from given,
2x + 8 = 5x + 7 + 4
5x -2x = 8 - 11
3x = -3
x = -1

Now,
JL = 2x + 8
JL = 2 * -1 + 8
JL = 6

Thus, the total numerical length of the segment JL is 6 units.

The value of x for the given equation is -3/2.

The given equation is 5 = -2(x-1).

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Here, 5 = -2(x-1) can be written as 5=-2x + 2.

Now, 5-2=-2x

⇒ 3=-2x

⇒ x=-3/2

Therefore, the value of x for the given equation is -3/2.

Step-by-step explanation:

First subtract the read pages with the unread pages which is 168.

Then let 21 pages = to one hour then 168pages(the remaining pages) = x then cross multiply and divide then your answer will be 8

Answer:

49

Step-by-step explanation:

First, multiply 5 on both sides:

2n = 50

Then, we divide 2 on both sides:

n = 25

Now we got the value of n, let's calculate 2n - 1.

First, multiply 2 by n so we can get 2n:

2 * 25 = 50

Then, we calculate 50 - 1:

We got 49, and that's the answer ^^

Hope this helps!

The value of 2n-1 is 49 if 2n/5=10, after applying the concept of a linear equation and the value of n is 25.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

2n/5 = 10

2n = 50

n = 25

Plug the value of n in the expression 2n - 1

= 2(25) - 1

= 49

Thus, the value of 2n-1 is 49.

The value of temperature in Kelvin K which has the value 240 degree in Fahrenheit F is 275 K.

The formula to convert a temperature from Kelvin K to Fahrenheit F is,

[tex]F=95(K-273.15)+32[/tex]

Here, K is Kelvin and F is Fahrenheit.

Solve the formula for K in the following way,

[tex]F=95(K-273.15)+32[/tex]

Subtract 32 both side,

[tex]F-32=95(K-273.15)+32-32\\F-32=95(K-273.15)[/tex]

Divide, with 95, both side of equation,

[tex]\dfrac{F-32}{95}=(K-273.15)\\\dfrac{F-32}{95}=K-273.15\\\dfrac{F-32}{95}+273.15=K[/tex]

This is the solved equation for K.

To convert 240∘ F to Kelvin K, put the value in the formula given in above equation,

[tex]\dfrac{F-32}{95}+273.15=K\\\dfrac{240-32}{95}+273.15=K\\\dfrac{208}{95}+273.15=K\\2.12+273.15=K\\275.27=K\\K\approx 275[/tex]
