Answer:

Step-by-step explanation:

500 / 5 = 100 (that's 1 fifth, so 2 fifths will be 200)

200 / 12.5 = 16 (he will have to work 16 hours to get $200)

the inequality would be:

x * 12.5 >= 500 * 0.4 (something like that)

Answer:

x = 3

Step-by-step explanation:

6x - 7y = 4

We are given that y = 2

6x - 7(2) = 4

6x - 14 = 4

Add 14 on both sides to leave the 6x alone

6x = 18

Divide by 6 to isolate x and find the value of x

x = 3

We can further prove this by putting in the value of x

6(3) - 7(2) = 4

18 - 14 = 4

Which is correct

Answer:

Step-by-step explanation:

Answer:

See below for answer

Step-by-step explanation:

A.  y = 0.85x + 15     when x = 30

     y = 0.85(30) + 15

     y = 40.5

     y = 0.85x + 15        when x = 100

     y = 0.85(100) +15

     y = 100

B.    y = 0.85x + 15          when y = 185

      185 = 0.85x + 15

        185 - 15 = 0.85x

          170 = 0.85x

           170/0.85 = x

               200 = x

Answer:

$83 million

Step-by-step explanation:

29% of the charity's donated funds.

$24.1 million = donation

Let x = the total amount of donated funds

29/100 • x = 24.1

x = 24.1 • 100/29

x = 83.10

=83

We want to get a system of inequalities that models the given situation.

The solutions are:

a) The system is:

And the graph can be seen at the end.

b) A solution can be x = 12 and y = 2

c) x = 8 and y = 1 is not a solution.

First, we need to define two variables:

a) First, we know that you must at least 8 hours per week in the grocery store, then:

x ≥ 8

We know that you need to earn at least $120 per week, then we have the inequality:

x*$10 + y*$15 ≥ $120

And you don't want to work more than 20 hours per week, this gives:

x + y ≤ 20.

We also add the trivial restriction:

y ≥ 0

Then the system is:

The graph can be seen at the end.

b) The solution region is the interception of the four shaded regions (is the dark blue part).

A solution in that region can be:

x = 12

y = 2

c) The point x = 8, y = 1 is graphed, you can see that it is outside the solution region, thus, this is not a solution.

Answer:

1. Hence, the answer is $74.50

2. Hence, the answer is 16.

Step-by-step explanation:

1. Given: Natalie and her friends decide to rent 4 lanes at regular cost for a party. Ten people need to rent shoes, adn 4 people are members.

To find: What is the total cost for the party?

Solution:

Since Natalie and her friends wanted to rent four lanes, we need to calculate this at REGULAR cost.

4 * 9 .75 = 39

Now since 10 people want to rent shoes, and 4 people are members, we subtract.

10 - 4 = 6

6 nonmembers

4 members

6 times the amount of shoe rental for 6 * 3.95 - 23.70

non members

4 times the number of members shoe rental 4* 2.95

11. 80

Now add the quantities

39 + 11.80 + 23.70 += 50.80 + 23.70 =

74.50

Now, our answer is 74.50

Answer:

x=5

Step-by-step explanation:

To solve for the value of x, you have to get x by itself.  So to get rid of the 3, divide both sides by 3.  3x/3 leaves x.  15/3 leaves 5.  So you're left with x=5.

The solution of expression 3x = 15 is,

⇒ x = 5

We have to given that,

An expression to simplify,

⇒ 3x = 15

We can simplify the expression for value of x,

⇒ 3x = 15

Divide both side by 3,

⇒ 3x/3 = 15 / 3

⇒ x = 5

Therefore, The solution of expression 3x = 15 is,

⇒ x = 5
