Sorry to bother you but I am so bad at math plz help

Question:

Here are five sums. Use the distributive property to write each sum as a product with two factors.

[tex](a)\ 2a + 7a[/tex]      [tex](b)\ 5z - 10[/tex]    [tex](c)\ c - c^2[/tex]      [tex](d)\ r + r+ r+ r[/tex]    [tex](e)\ 2x - \frac{1}{2}[/tex]

Answer:

[tex](a)\ 2a + 7a = 9a[/tex]

[tex](b)\ 5z - 10 = 5(z - 2)[/tex]

[tex](c)\ c - c^2 = c(1 - c)[/tex]

[tex](d)\ r + r + r + r = 4r[/tex]

[tex](e)\ 2x - \frac{1}{2} = \frac{1}{2}(4x - 1)[/tex]

Step-by-step explanation:

Required

Apply distributive property

[tex](a)\ 2a + 7a[/tex]      

Apply distributive property [Factor out a]

[tex]2a + 7a = a(2 + 7)[/tex]

[tex]2a + 7a = a(9)[/tex]

Open bracket

[tex]2a + 7a = a*9[/tex]

[tex]2a + 7a = 9a[/tex]

[tex](b)\ 5z - 10[/tex]    

Express 10 as 5 * 2

[tex]5z - 10 = 5z - 5*2[/tex]

Apply distributive property [Factor out 5]

[tex]5z - 10 = 5(z - 2)[/tex]

[tex](c)\ c - c^2[/tex]      

Express c as c * c

[tex]c - c^2 = c - c * c[/tex]

Apply distributive property [Factor out c]

[tex]c - c^2 = c(1 - c)[/tex]

[tex](d)\ r + r+ r+ r[/tex]    

Express r as r * 1

[tex]r + r + r + r = r * 1 + r * 1 + r * 1 + r *1[/tex]

Apply distributive property [Factor out 1]

[tex]r + r + r + r = r(1+1+1+1)[/tex]

[tex]r + r + r + r = r * 4[/tex]

[tex]r + r + r + r = 4r[/tex]

[tex](e)\ 2x - \frac{1}{2}[/tex]

Express 2x as 4x/2

[tex]2x - \frac{1}{2} = \frac{4x}{2} - \frac{1}{2}[/tex]

Apply distributive property [Factor out 1/2]

[tex]2x - \frac{1}{2} = \frac{1}{2}(4x - 1)[/tex]

Answer:

x = $11

Step-by-step explanation:

5x = $55

9x = $99

2x = $22

In order to find the relationship between x and y, all we have to do is divide y by the term.

                                                       $55 ÷ 5 = 11

                                                       $99 ÷ 9 = 11

                                                       $22 ÷ 2 = 11

                             Therefore, each ticket sold is $11, or x = $11

Answer:

Independent = Milk left in the gallon jug

Dependent = cups of milk poured

Step-by-step explanation:

In an experiment or a research, a variable is defined as the thing or a phenomenon that you are trying to found out or measure. Variables can be independent variable as well as the dependent variable.

Independent variable is the variable that the researcher or the experimenter can change or manipulate in the research. This variable does not depend on others and thus stands alone. Its value can be change or altered to find the changes in the dependent variables. They are used as treatment variables.

Whereas, the dependent variables are those variables that are dependent on the values of the independent variables. It is considered as the effect of the independent variable. An independent variable is often manipulated to measure the outcome in the dependent variable.

In the context, the cups of milk poured is the dependent variable and the independent variable is the amount of milk left in the jug.  

Answer:

Step-by-step explanation:

(-2, -3)  (-1, -1)

(-1 + 3)/(-1 + 2)= 2/1 = 2

y + 3 = 2(x + 2)

y + 3= 2x + 4

y = 2x + 1

Answer: If Frank and John can meet these goals with their diets , they will weigh same after 9.6 weeks and they will weigh 179.2 pounds.

Step-by-step explanation:

Let x = Number of weeks.

As per given question ,

Weight of Frank after x weeks = 160+2x (pounds)

Weight of John after x weeks = 208-3x (pounds)

When Weight of Frank= Weight of John

Weight of Frank after 9.6 weeks = 160+2(9.6) = 179.2 pounds

Weight of John after 9.6 weeks = 208-3(9.6)=179.2 pounds

Hence, If Frank and John can meet these goals with their diets , they will weigh same after 9.6 weeks and they will weigh 179.2 pounds.

Answer:

  $45,395.39

Step-by-step explanation:

The formula for an amount earning compound interest is ...

  A = P(1 +r/n)^(nt)

where principal P is invested at annual rate r compounded n times per year for t years.

Using the given numbers, we have ...

  A = $10,000(1 +0.038/4)^(4·40) ≈ $45,395.39

The charity will receive $45,395.39.

Answer:5p-+q+r

Step-by-step explanation:

Answer:

x = 5.4

Step-by-step explanation:

Corresponding sides are in proportion, that is

[tex]\frac{x}{7.2}[/tex] = [tex]\frac{3}{4}[/tex] ( cross- multiply )

4x = 21.6 ( divide both sides by 4 )

x = 5.4

Answer:

square root of 109

Step-by-step explanation:

Use the Pythagorean Theorem to find x. The equation is a^2+b^2=c^2. In this case, a=3, b=10, and c=x. Plug that into the equation to get 9+100=c^2. Simplify that to get 109=c^2. Then divide each side by squared to get square root of 109=c.

Answer:

It is not infront of the 5 because when mutiplying it goes above a whole number so the . has to move back.

Step-by-step explanation:

Answer:

x=-4

Step-by-step explanation:

1. Distribute

3(2x+8)=0

6x+24=0

2. Subtract 24 from both sides.

6x+24=0

6x+24-24=0-24

3. Simplify

6x=-24

4. Divide both sides of the equation by the same term

6x=-24

[tex]\frac{6x}{6}[/tex] = [tex]\frac{-24}{6}[/tex]

5. Simplify

x=-4

And thats the answer.

I hope this helps        :)

Step-by-step explanation:

The medium is the number in the middle in an assorted number line so do least from greatest and pick one out of the middle

Answer: 1=65° and 5=43

Step-by-step explanation:

Question 1:

Angles on a straight line always add up to 180°.

So to find the angle of x on the first question you have to do 180-115=65°

You would have to use this method for questions 2, 3 and 4 as well.

Question 5:

Right angles always add up to 90° so to work out what x is you would have to do 90-47=43

You would have to use this method for questions 6, 7 and 8.

Hope this helps :)

Answer:

41.29 cm²

Step-by-step explanation:

From the question,

Area of the shaded portion = Area of the circle - area of the square.

A' = πr²-L²...… Equation 1

Where A' = Area of the shade portion, r = radius of the circle, L = length of the square, π = pie

Given: r = 4 cm, L = 3 cm

Constant: π = 22/7.

Substitute these values into equation 1

A' = [(22/7)×4²]-3²

A' = 50.29-9

A' = 41.29 cm²

Hence the area of the shaded portion is 41.29 cm²

Answer:

Bill will earn more interest

He will earn $ 20,448.67 from his investment

Step-by-step explanation:

Firstly let us calculate Jim's earnings based on simple interest

A = P(1 + rt)

Calculation:

First, converting R percent to r

a decimal

r = R/100 = 3.5%/100 = 0.035 per year.

Solving our equation:

A = 15000(1 + (0.035 × 25)) = 28125

A = $28,125.00

The total amount accrued, principal plus interest, from simple interest on a principal of $15,000.00 at a rate of 3.5% per year for 25 years is $28,125.00 for Jim

Now let's us calculate bill's investment based on compound interest

Equation

A = P(1 + r)^t

A=15000(1+0.035)^25

A=15000(1.035)^25

A=15000*2.36324498427

A = $ 35,448.67

We see that Bill will earn

$ 20,448.67 from his investment
