Derek spends $8.50 a day on school breakfasts and lunches. How much does he spend on food in a school week? (Hint: there are 5 days in a school week)

Answer:

x = 28 (So it takes 28 hours for the temperature to reach 0°C.)

y = -70 (So the temperature when the experiment begins is −70°C.)

Step-by-step explanation:

To find the the x value, you remove the y value or replace it with 0.

0 = 5/2x - 70

Next you move the variable.

70 (2/5) = x           (multiply 70 by 2 to get 140 and divide that by 5)

And now you simplify to get:

28

To find the y value, you remove the x value or replace it with 0.

y =  0 - 70

And now you simplify to get:

-70

x = 28

y = -70

x = 28 (So it takes 28 hours for the temperature to reach 0°C.)

y = -70 (So the temperature when the experiment begins is −70°C.)

Answer:

a). Nadia made a total of $825 last week in commission sales

b). The total amount Nadia in commission in 2011=$42,900

Step-by-step explanation: Step 1

Express the amount in commission she earns from her sales as follows;

C=S×r

where;

C=commission earned

S=total value of stock sales

r=commission rate

In our case;

C=unknown

S=$7,500

r=11%=11/100=0.11

replacing;

C=11% of 7,500

C=(11/100)×7,500

C=0.11×7,500=825

Nadia made a total of $825 last week in commission sales

b). To express the total amount she made in 2011, we derive the formula below;

Total amount (2011)=Average weekly commission×number of weeks in 2011

where;

Average weekly commission=$825

number of weeks in 2011=52

replacing;

Total amount (2011)=(825×52)=42,900

The total amount Nadia in commission in 2011=$42,900

Answer: 16 acres

Step-by-step explanation: we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form  or

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Let

x ----> the number of acres

y ---> total operating costs

we have the ordered pair (20,551,520)

For x=20 acres, y=$551,520

Find the value of the constant of proportionality k

substitute the values of x and y

The linear equation is equal to

Find out how many acres are on a farm with a total operating cost of $441,216

so

For y=$441,216

substitute in the linear equation the value of y and solve for x

Step-by-step explanation:

you just move the dot 2 to the right when it is positive. When it is negative you move the dot to left.

Answer:

1756.5

Step-by-step explanation:

10^2 will equal 100, so you multiply 17.565 by 100. Move the numbers to the left twice and you get 1756.5

Answer:

Distributive property is when you multiply or add the numbers in the parentheses equally to the number outside the parentheses.

That probably isn't a good answer, here's what I found on google:

To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

Step-by-step explanation:

I'll do #10 as an example:

(x-5)y

distribute the numbers-  y(x)-y(5)

without the parentheses-  yx-y5

you can't really get an answer by multiplying a number and a variable, or a variable and a variable, so you just leave them and take the parentheses.

Here's #11:

-4(2a-3b+c)

distribute the numbers-  (-4*2a)-(-4*3b)+(-4c)

solve-  -4*2= -8

-4*3= -12

-8a-(-12)b+4c

*I dunno how to use parentheses for negative numbers but what I did for distributing is pretty much the same thing

Hope this helps you.

Step-by-step explanation:

Given

5g + 12 = 2g + 18 ( subtract 2g from both sides )

3g + 12 = 18 ( subtract 12 from both sides )

3g = 6 ( divide both sides by 3 )

x = bath bombs

So 3x is three times as many bath bombs, then the plus one makes it so that the soaps sold is more than three times the amount of bath bombs sold

Answer:

Step-by-step explanation:

y + 2 = 12(x - 3)

y + 2 = 12x - 36

y =12x - 38

The required equation of the line passing through (3, -2) and parallel to the line represented by y = 12x - 2 is y = 12x - 38.

Slope is usually denoted by m.

Slope is defined as the change in the value of the y coordinates with respect to the change in the value of x coordinates.

Equation of a line in slope intercept form is y = mx + c where m is the slope and c is the y-intercept.

y-intercept is the y coordinate when x coordinate equals zero.

It is given that the required line is parallel to y = 12x - 2.

Comparing with the slope intercept form of the line, the slope of  y = 12x - 2 is 12.

Slope of two parallel lines are equal.

So the slope of the required line = 12

It is also given that required line passes through the point (x, y) = (3, -2).

Substituting these values,

-2 = (12 × 3) + c

-2 = 36 + c

c = -2 - 36

c = -38

So the required equation is found by substituting m = 12 and c = -38.

y = 12x - 38

Hence the equation of the line passing through (3, -2) and parallel to the line y = 12x - 2 is y = 12x - 38.
