Answer:

2(30-7x)

Step-by-step explanation:

=14+14x-65-9

=14+14x-79

=60+14x

=2(30-7x)

Answer:

No solution

Step-by-step explanation:

Because when you add 5 on both sides to take away the negative 5 it does not show a true statement. Since:

7x does not equal 7x + 10

I'm pretty sure it's this:

Answer:

y=a( 1+  r/n)^ nt

growth is a= 2500     yearly is n= 1

y= 2500( 1+ .065/1)^ 1.7  =   $3884.97

Step-by-step explanation:

meg played at lace of 3.3333 tiles a minute so has to be over 25 tiles

The correct options are C and D.

Important information:

The rate per tile of Meg is:

[tex]\text{Rate}=\dfrac{\text{Time}}{\text{No. of tiles}}[/tex]

[tex]\text{Rate}=\dfrac{50}{15}[/tex]

[tex]\text{Rate}=3.333...[/tex]

Calculate the rates per tile for each option.

[tex]\frac{85}{20}=4.25[/tex]

[tex]\frac{85}{24}=3.54167...[/tex]

[tex]\frac{85}{28}=3.0357...[/tex]

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

[tex]\frac{4}{1}=4[/tex]

From the above calculation is clear that the time spent per tile is less than Meg's rate in options C and D.

Therefore, the correct options are C and D.

My example: 7(2 + 7) = 7(2) + 7(7)

Formula: x(y + x) = x*y + x*x

Step-by-step explanation:

The distributive property can be represented by the following equation:

x(y + x) = x*y + x*x

Since you are looking for any example, let's plug in a few numbers to the above equation.

Ex) x = 7, y = 2

The example equation with these values is 7(2 + 7)

Solving With Distributive Property:

x(y + x)

Substitute

7(2 + 7)

Simplify using distributive property

7(2) + 7(7)

14 + 49 = 63

Solving using PEMDAS and solving inside the parenthesis first

7(2 + 7)

7(9)

63

The above is an example of solving/siplifying equations with and without the Distributive Property.

Since these numbers are the same, we can conclude that the formula for the distributive property above is correct.

Again, you are looking for an example, so simply pick a value for x and y and substute into this equation: x(y + x) = x*y + x*x

I used 7 and 2 above, but any numbers will work as you are distributing the value outside the parenthesis.

Hope this helps! Let me know if you have any questions.

PEMDAS simpliy means that the solving of equations can be solved by going in the following order:

- Parenthesis (P)

- Exponents (E)

- Multiplication and Division left to right of the expression/equation (M/D)

- Addition and Subtraction (A/S)

This is just a helpful little refrence when applying the order of operations.

Answer:

The value of h is [tex]\frac{5}{2}[/tex] units

Step-by-step explanation:

In the given figure

∵ Every two opposite sides of the parallelogram are equal

∴ The length of the base of the height h is 3 units

∵ The area of the parallelogram = [tex]\frac{15}{2}[/tex] units

∵ Area of parallelogram = b × h

→ Substitute the values of the area and the base in the rule above

∴ [tex]\frac{15}{2}[/tex] = 3 × h

∴ [tex]\frac{15}{2}[/tex] = 3h

→ Divide both sides by 3 to find h

∵  [tex]\frac{15}{2}[/tex] ÷ 3 = 3h ÷ 3

∴ [tex]\frac{15}{6}[/tex] = h

→ Simplify the fraction by divide up and down by 3 and switch the 2 sides

∴ h = [tex]\frac{5}{2}[/tex] units

Answer:

6 liters

Step-by-step explanation:

2 liters of milk will need 6 liters of water.

Given is that a recipe says - "3 parts water to 1 part milk".

Now, we can write that -

3 parts water needs 1 part milk

This means, 1 litre milk needs 3 liters of water.

Then, 2 liters of milk will need (2 x 3) = 6 liters of water.

Therefore, 2 liters of milk will need 6 liters of water.

Answer:

1.18

Step-by-step explanation:

Given the data:

X 0 1 2 3 4 5

P(X) 0.10 0.20 0.45 0.15 0.05 0.05

E(x) = (0*0.1) + (1*0.2) + (2*0.45) + (3*0.15) + (4*0.05) + (5*0.05) = 2

Var(x) = [((0^2)*0.1)+((1^2)*0.2)+((2^2)*0.45)+((3^2)*0.15)+((4^2)*0.05)+((5^2)*0.05)] - 2²

5.4 - 4

= 1.4

Standard deviation = √var(x)

Standard deviation = √1.4

Standard deviation = 1.183

Standard deviation = 1.18

Answer:

Step-by-step explanation:

Given:

A random survey of 30 students found that 17 played a musical instrument.

Total number of students = 450

To find:

Estimated number of students who do not play an instruments.

Solution:

A random survey of 30 students found that 17 played a musical instrument.

Let E be the event that student play an instrument.

So, probability that a student plays an instrument is

[tex]P(E)=\dfrac{17}{30}[/tex]

Probability that a student do not play an instrument is

[tex]P(E')=1-P(E)[/tex]

[tex]=1-\dfrac{17}{30}[/tex]

[tex]=\dfrac{13}{30}[/tex]

Now, number of students who do not play an instruments is

[tex]450\times P(E')=450\times \dfrac{13}{30}[/tex]

[tex]450\times P(E')=195[/tex]

Therefore, 195 students do not play an instrument.

Answer:

35 Calories

Step-by-step explanation:

15 is 1/4 of 60

60/15 = 4

140/4 = 35

Since 15 is 1/4 the size of 60, the number of calories will be 1/4 the amount as well. That is why you divide 140 by 4 to find the total calories for the mass of 15.

Answer:

37 R0

Step-by-step explanation:

740/20=37, so there is no remainder.

I hope this helps you! Have a great day c:

Dividing 20 by 740 gives us remainder 20 and quotient 0.

To find the result of 20 divided by 740 with a remainder,

Perform the division and take note of the quotient and remainder.

20 ÷ 740 = 0 with a remainder of 20.

Division is a mathematical operation that involves splitting a number (the dividend) into equal parts,

with a divisor indicating how many parts we want to split it into.

The quotient is the number of equal parts, and the remainder is what's left after have split the dividend into as many equal parts as possible.

20 divided by 740, we are trying to find out how many times 740 can fit into 20.

Since 740 is much larger than 20, it cannot fit even once.

So, the quotient is 0, indicating that 0 whole units of 740 can fit into 20.

However, there is a remainder of 20.

The remainder represents the portion of 20 that cannot be evenly divided by 740.

It is what remains after we have divided the dividend by the divisor as many times as possible.

Therefore, 20 divided by 740 is 0 with a remainder of 20.
