equation for the amount of sodium in 4 slices of bread 130,260, 390, 520

Answers

We can use a linear equation in this data set because we have a given rate of increase (sodium) over a given quantity (slices).

Therefore, we need to calculate the rate of change between both variables; how much sodium increases per the amount of slices of bread.

Calculating the slope:
• We are not given two coordinate pairs, so to calculate the slope, we need to know how much sodium is added per each piece of bread.
• We will take the difference of the sodium increases in the data set:

260-130 = 130

520-390 = 130

Therefore, the slope or rate of change is 130mg per 1 piece of bread. We can put this into a slope-intercept equation in the form of y=mx+b

Y=130x is the equation.

PLS HELP Which expression is equivalent to 7y−3x−2y?

2xy

7y−5x

4x−2y

5y−3x

Answers

Answer:

is a equation? because you can do this 3x-2=7 and the answer is x=3

7y - 3x - 2y is equivalent to 5y - 3x.

You must combine like terms. Since 7y and - 2y have like terms, we could combine them by subtracting 2y from 7y, leaving you with 5y.

7y - 3x - 2y

= 7y - 2y - 3x

= 5y - 3x.

The graph number [2], represents a function.

What is a expression? What is a mathematical equation? What is Equation modelling ?

A mathematical function is made up of terms (constants and variables) separated by mathematical operators having a dependent and independent variable. A mathematical equation is used to equate two expressions. For any function y = f(x), Domain is the set of all possible values of [y] that exists for different values of [x]. Range is the set of all values of [x] for which y exists.

We have some graphs of relations as shown.

Only the graph number [2], represents a function as for a single value value of [x], a single unique value of [y] exists.

Therefore, the graph number [2], represents a function.

share out £20 between bill and sue in the ratio 3:2

Answers

Answer:

12:8

Step-by-step explanation:

Bill receives £12, and Sue receives £8.

In order to divide £20 between Bill and Sue in the ratio 3:2, we first need to find the total number of parts in the ratio. The sum of the parts in a 3:2 ratio is 3 + 2 = 5.

Next, we determine the value of one part by dividing the total amount (£20) by the total number of parts (5): £20 ÷ 5 = £4.

Now, we can allocate the money to Bill and Sue according to their shares in the ratio. For Bill, who gets 3 parts, we multiply his share of one part (£4) by 3: £4 × 3 = £12. For Sue, who gets 2 parts, we multiply her share of one part (£4) by 2: £4 × 2 = £8.

Thus, Bill receives £12, and Sue receives £8.

In mathematical terms, we can represent the division of £20 between Bill (B) and Sue (S) as follows:

Let the ratio be represented as B:S = 3:2.

Total parts in the ratio = 3 + 2 = 5.

Value of one part (Vp) = Total amount / Total parts = £20 ÷ 5 = £4.

Amount received by Bill (Ab) = 3 parts × Vp = 3 × £4 = £12.

Amount received by Sue (As) = 2 parts × Vp = 2 × £4 = £8.

Thus, Bill receives £12, and Sue receives £8.

In summary, when dividing £20 between Bill and Sue in the ratio 3:2, we follow the steps of finding the total parts in the ratio, calculating the value of one part, and then distributing the amount based on each individual's share in the ratio.

Solve for m: m=−(4+m)+2

Answers

Answer:

m = - 1

Step-by-step explanation:

m = -4 - m + 2    Combine

m = -2 - m          Add m to both sides

m+m = - 2          Combine

2m = - 2            Divide by 2

m = -2/2

m = - 1

m=−(4+m)+2

Simplify both sides of the equation.

m=−(4+m)+2

m=−m+−4+2

m=(−m)+(−4+2)

m=−m+−2

m=−m−2

Add m to both sides.

m+m=−m−2+m

2m=−2

Divide both sides by 2.

2m/2=−2/2

m=−1

Answer:

A) 33

B) 58

Step-by-step explanation:

A is 33 because supplementary angles add up to 180 in total. 180 - 147 = 33, so its supplementary angle would be 33 degrees.

B is 58 because complementary angles add up to 90 in total. 90 - 32 = 58, so the complementary angle would be 58 degrees.

Answer:  33° and 58°

Step-by-step explanation:

147° and 32°

Two angles are called complementary when their measures add to 90 degrees. (90° - 32°) = 58°

Two angles are called supplementary when their measures add up to 180 degrees.  (180°-147°) = 33°
