Answer:

6%

Step-by-step explanation:

540 ÷ 9000 = .06

.06 = 6%

Answer:

8 = 4.40

9 = x

9(4.40)=39.6

39.6/8=4.95

So 19 tokens cost $4.95.

Step-by-step explanation:

The 19 tokens cost $104.5.

What is Unitary method?

In order to solve a problem for two different values of a quantity, its unit value is first derived. This method is known as unitary method.

Given that,

The price of 8 tokens is $4.40.

In order to find the cost for 19 tokens the unitary method is used as,

The cost for 1 token = $4.40/8

                                 = $5.5

So, the cost for 19 tokens is 19 × 5.5 = $104.5

Hence, the cost for 19 tokens is $104.5.

Answer:

(x^3 + 6 x^2 + 3 x + 4)/x

Step-by-step explanation:

Simplify the following:

x^2 + 6 x + 3 + 4/x

Put each term in x^2 + 6 x + 3 + 4/x over the common denominator x: x^2 + 6 x + 3 + 4/x = x^3/x + (6 x^2)/x + (3 x)/x + 4/x:

x^3/x + (6 x^2)/x + (3 x)/x + 4/x

x^3/x + (6 x^2)/x + (3 x)/x + 4/x = (x^3 + 6 x^2 + 3 x + 4)/x:

Answer: (x^3 + 6 x^2 + 3 x + 4)/x

Answer:

198

Step-by-step explanation:

t20=a+19d.......1

t40=a+39d.......2

t2=a+d=2.........3

According to ques,

t40-t20=a+39d-(a+19d)=40

or,20d=40

or,d=2

Now ,putting the value of d in equation 3,we get,

a=0

t100=a+99d

=0+99×2

=198

Step-by-step explanation:

Answer:

The nearest option is -3 (negative 3)

So, Option B is correct.

Step-by-step explanation:

We need to solve the inequality [tex]7 \leq -3x-4[/tex]

Solving:

Step 1: Switching sides of inequality and reversing the inequality

[tex]-3x-4\geq 7[/tex]

Step 2: Adding 4 on both sides

[tex]-3x-4+4\geq 7+4\\-3x\geq 11[/tex]

Step 3: Dividing both sides by -3 and reversing the inequality

[tex]\frac{-3x}{-3}\leq \frac{11}{-3} \\x\leq -3.6\\[/tex]

The nearest option is -3 (negative 3)

So, Option B is correct.

The equation that is equivalent to the expression 7-2(3x+4)=8x is

-6x - 1 = 8x.

Option B is the correct answer.

We have,

To find the equation that is equivalent to 7-2(3x+4)=8x, simplify the given equation by applying the distributive property and combining like terms.

7 - 2(3x + 4) = 8x

First, distribute the -2 to the terms inside the parentheses:

7 - 6x - 8 = 8x

Combine like terms:

-6x - 1 = 8x

Thus,

The equation that is equivalent to the expression 7-2(3x+4)=8x is

-6x - 1 = 8x.

Answer:

y=mx+b is the form to write this equation. M is the slope and B is the y intercept. therefore:

y=4x-9

Step-by-step explanation:

Answer:

8. The coordinates (0,0) represent the fact that when 0 minutes has passed, the horses have gone 0 miles because they hadn't started yet.

9. From the graph, it looks like horse A takes 4 minutes and horse B takes 2.5 minutes (aka 2 minutes and 30 seconds) to travel 1 mile.

10. For A: y = (1/4)x

For B: y = (2/5)x

11. For A: 3 miles

For B: (24/5) miles, or 4 and (4/5) miles.

12. Can't see the entire problem sorry.

Step-by-step explanation:

9. You find this by going to y=1 and look towards the right till you find the point the line intersects with y=1. Then find the x value by finding the corresponding number on the x axis.

10. A linear function will look something like this: y = mx+b, where y is the y value, x is the x value, m is the slope, and b is the y-intercept. Since both lines start from 0, you don't have to write the y-intercept since there's no point in writing +0. To find slope, you find delta y over delta x. Basically just find the difference of two y values and the difference of two x values from the same coordinate in the same order. I know that sounds really confusing but your teacher will probably teach this later on.

11. x represents the time, so just substitute x as 12 in the equation.

Step-by-step explanation:

Since we know how far she can walk in 1/5 (one fifth) of an hour, if we multiply this distance by 5, we will find out how far she can walking in 5/5 (five fifths) of an hour, or to be clear: in one hour.

So, 5 x 1/4 miles = 5/4 or 1.25 miles per hour

Jazmeen can walk 1.25 miles in one hour.
