In x years from now, Robert will be k

years old. How old was Robert m

years ago?

A) x-(k+m)

B) k-x

C) k-x-m

D) x-(k-m)

**Answer:**

* I think the answer would be C, because*

**Step-by-step explanation:**

*Example:*

*If in 6(x) years Robert is 16(k), how old was he 3(m) years ago?*

*First, you would have to find out how old Robert is now, 16-6=10*

*Then, you would take 10, his current age, and subtract 3(m) 10-3=7*

*I hope this helped, good luck!*

Since Robert will be [tex]k[/tex] years old in [tex]x[/tex] years, he must be [tex](k-x)[/tex] years old now.

[tex]Robert=(k-x)old[/tex]Robert was [tex](k-x)-m[/tex] years old; [tex]m[/tex] years ago.

[tex]Robert=(k-x)-m[/tex]The answer is **C.**

A small publishing company is planning to publish a new book. The production costs will include one-time fixed costs (such as editing) and variable costs (such

as printing). There are two production methods it could use. With one method, the one-time fixed costs will total $49,631, and the variable costs will be $10.25

per book. With the other method, the one-time fixed costs will total $12,209, and the variable costs will be $23.75 per book. For how many books produced will

the costs from the two methods be the same?

**Step-by-step explanation:**

for both costs to be the same, the sum of the fixed and the variable costs must be the same.

so,

49631 + 10.25x = 12209 + 23.75x

37422 = 13.50x

x = 37422 / 13.5 = 2,772

the costs of both methods will be the same for 2,772 produced books.

Sarah spent 2 h more travelling by train than she did by bus. The train averaged 70 km/h and the bus 50 km/h. The total distance travelled was 740 km. How far did she travel by bus?

**Answer:**

250 km

**Step-by-step explanation:**

Sarah traveled a **total of 740 km**, **2 hours more** at a speed of **70 km/h** than at a speed of **50 km/h**. You want to know **how far she traveled** at **50 km/h**.

The relations between time, speed, and distance are ...

distance = speed × time

time = distance/speed

If 'd' represents the distance (km) Sarah traveled by bus (at 50 km/h), then the time (hours) required was ...

time = d/50

The time at 70 km/h is 2 hours more, and the total distance is ...

total distance = (distance at 50 km/h) + (distance at 70 km/h)

740 = d + 70(d/50 +2)

SolutionSimplifying the equation, we have ...

740 = 2.4d +140

600 = 2.4d . . . . . . . . subtract 140

d = 250 . . . . . . . . . . . divide by 2.4

**Sarah traveled 250 km by bus**.

Enter an equation in standard form that models the linear situation. A bathtub that holds 53 gallons of water contains 18 gallons of water. You begin filling it, and after 5 minutes, the tub is full.

The **linear** **equation **which represents the **situation **or the amount of water in the **bathtub** in terms of the number of **minutes **is y = 7x + 18.

A **straight line **on the **coordinate plane **is represented by a** linear **function.

In another word, a **linear** function is a function that **varies linearly **with respect to the **changing variable**.

Let's suppose the **number **of **minutes **by x and the **amount **of **water **by y

As per the given question,

The amount of water (y) initially (x = 0) is 18 gallons.

The **first point **(0,18).

The amount of water (y) at x = 5 is 53 gallons.

The **second point **(5,53).

The linear equation is given as y = mx + c where m is the **slope**.

Slope m = (53 - 18)/(5 - 0) = 7

**Substitute **(0,18) →

18 = 7(0) + c

c = 18

So the **equation **become as,

y = 7x + 18.

Hence "The **linear** **equation **which represents the **situation **or the amount of water in the **bathtub** in terms of the number of **minutes **is y = 7x + 18".

Nathan sells jewelry and earns a 9.75% commission on every piece

he sells. How much commission would he earn on a bracelet that

sold for $220? Use any strategy

**Answer:**

$21.45

**Step-by-step explanation:**

You want to know the amount of a **9.75% commission on $220**.

The amount of the commission is the product of the commission rate and the sales amount to which it is applicable. A 9.75% commission on $220 will be ...

9.75% × $220 = 0.0975 × $220 = $21.45

**Nathan would earn a commission of $21.45 on the sale**.

__

*Additional comment*

We know that a 10% commission can be found by moving the decimal point on the sale amount. A 10% commission on $220 will be $22.

The commission rate of 9.75% is 1/4% less than 10%. 1/4% can be found in two steps: find 1%, then find 1/4 of that.

As with 10%, the 1% amount can be found by moving the decimal point. 1% of $220 is $2.20. One-quarter of that will be $2.20/4 = $1.10/2 = $0.55.

This is the amount we must subtract from the 10% value to make it be 9.75%.

The **9.75% commission amount** is $22.00 -0.55 = **$21.45**.

(The point of using a strategy like this is that you can do the math mentally.)

A farmer has bushels to sell at a roadside stand. sells an average of

each day. Represent the total change in the number of bushels for sale after.

The **total change** in the number of bushels for sale is 64.1 bushels.

Given

A farmer has 160 bushels of apples to sell at her roadside stand. Every day, she sells around a 13 7/10** bushel.**

Let us calculate the **overall change** in the number of bushels she has available for sale after 7 days.

137/10

Now we'll figure out how many bushels she'll sell in seven days.

7 x 137/10

95.9

In 7 days, the farmer will sell 95.9 bushels. To calculate our overall change, subtract this figure from the total number of** bushels **of **apples.**

165 - 95.9 = 64.1

Thus, a total of 64.1 **bushels** have been added to the amount of bushels available for sale.

Write the equation of the line in fully simplified slope-intercept form.

**Step-by-step explanation:**

a slope-intercept form :

y = ax + b

"a" is the slope, "b" is the y-intercept (the y-value when x = 0).

the slope is the ratio (y coordinate change / x coordinate change) when moving from on point on the line to another.

"b" we can read off the graph : when x = 0, then y = -5.

so, b = -5.

for the slope let's pick 2 points. your teacher has kindly marked already points with integer coordinates.

so, I pick (3, 1) and (4, 3).

x changes by +1 (from 3 to 4).

y changes by +2 (from 1 to 3).

so, the slope is

+2/+1 = 2/1 = 2

the equation is

y = 2x - 5

**Answer: y=2x-5**

**Step-by-step explanation:**

Choose two points on the graph: (0,-5) and (3,1)

The straight line equation is: y=mx+b

On **making b** the **subject** , the **formula** is b = (5/3)a .

in the question ,

it is given that

the formula is a = 3(2a-b), where the **subject is a** ,

we have to rewrite the formula with b as **the subject **.

So, the **given formula** is

a = 3(2a-b)

simplifying the RHS , we get

a = 3*2a - 3*b

a = 6a - 3b

on re arranging the terms , we get

3b = 6a - a

3b = 5a

Dividing both sides by 3 ,we get

3b/3 = 5a/3

Cancelling out 3 from LHS , we get

b = 5a/3

b = (5/3)a

Therefore , On **making** b the subject , the **formula** is b = (5/3)a .

Submit a 250 word minimum essay on the steps of solving for both the x and y intercept.

The essay will need to be in your own words of course, but the basic idea is to replace x with 0 and solve for y to get the y intercept. To get the x intercept, replace y with 0 and solve for x.

Here's an example

2x+5y = 10

Let's find the x intercept

2x+5y = 10

2x+5(0) = 10

2x = 10

x = 5 is the x intercept

Now we'll do the y intercept

2x+5y = 10

2(0)+5y = 10

5y = 10

y = 10/5

y = 2 is the y intercept

The x intercept is the location where the graph crosses the x axis. The y intercept is where the graph crosses the y axis.
