2x - 4 > 14

Add 4 to both sides:

2x > 14 + 4

2x > 18

Step-by-step explanation:

You buy a brand new wax candle that stands 6 inches tall. Knowing that the rate at which the wax melts is approximately 1/100 of an inch per minute, write a linear equation that could model this situation.

Answers

Answer:

y=-1/100x+6 or y=-1x+600

Step-by-step explanation:

6 inches is the Y intercept (600,0) if measuring by 1/100 or (6,0)

Since the wax is melting, the slope  is going to be negative

y=mx+6 or y=mx+600 either is fine and would yield the same results

y=-.01x+6, y=1/100x+6 or y=-1x+600

To explainn why 6 and 600 are both fine, 6 is measuring with full inches while the 600 is measuring with .01 inches. One graph will be full numbers while the other will be decimals.

Answer:

600 minutes total

Step-by-step explanation:

Inch = 100

1/100 every minute

100/100 = 1 inch and 100 minutes

600/100 = 6 inch and 600 minutes

Consider the equation: 5(3x 2 9) 5 2(6x 1 9).

Your answer is 42, that’s what I came up with because your equation doesn’t make a lot of sense to me sorry. But (3x2 9) = 15 + 5 = 20 +5 = 25 and (6x1 9) = 15 + 2 = 17 so 17+25= 42

The information below for two pay-as-you-go cell phone companies is given

On Call - 3.5 hours: $10
Talk Time - 1/2 hour:$1.25

a.) what is the unit rate in dollars for each company?
b.) Which company offers the best deal?
c.) Another company offers a rate of $0.05 per minute. How would you find the unit rate per hour?

Answers

Answer:

a) On Call: $2.86/hour

Talk Time: $2.50/hour

b) Talk Time offers the best deal.

c) $3/hour

Multiply 0.05 by 60 because there are 60 minutes in an hour.

Step-by-step explanation:

a) On Call: 10/3.5=2.86

Talk Time: 1.25/0.5=2.50

b) On Call>Talk Time

Talk Time offers the best deal.

c) 0.05x60=3

Multiply 0.05 by 60 because there are 60 minutes in an hour.

Answer:

Step-by-step explanation:

One company wants $10 per 3.5 hours, so they want 10 / 3.5 ≈ 2,86 dollars per hour (after rounding to the closest hundreths).

Second company wants $1.25 per half an hour, so they want 2 * 1,25 = 2,50 dollars per hour.

The unit rate is 2,86:2,50

Jason needs 2 ½ pounds of potatoes to feed 15 people at his Friendsgiving dinner. But, his friends just called and told him they’re each bringing more friends. How many pounds of potatoes will need to feed 50 people? Explain your reasoning.

Answers

Answer:

8 1/3, eight and one over three.

Step-by-step explanation:

First lets find the rate by dividing 15 by 2.5 You will get 6 meaning that six people eat 1 pound each. Now lets divide 6 from 6 and 1. This means that 1 person will eat 1/6 of the pounds of the potatoe. Then we can do 50 times 1/6 and we will get 8.3333. This means that Jason needs 8 and 1/3 pounds of potatoes to feed 50 people.

The value of y varies directly with x, when y = 4, and x = 9. What is the equation for the relationship?

Answers

Answer:

y  =  [tex]\frac{4}{9}[/tex]x

Step-by-step explanation:

Given parameters:

  y  = 4

   x  = 9

y varies directly as x ;

  Mathematically ;

            y ∝ x

So;

            y  = kx

k is the constant of proportionality;

  find k;

             k  = [tex]\frac{y}{x}[/tex]  

             k  = [tex]\frac{4}{9}[/tex]  

So,

  Equation of the relationship is;

            y  =  [tex]\frac{4}{9}[/tex]x

One printing machine printed 500 books in 40 hours this week. A second printing machine printed for 30 hours this week but printed books at twice the hourly rate of the first machine. How many books did the second machine print this week?

A.375
B.500
C.750
D.1,000

Can somebody help me plz

Answers

A. 375 would be the correct answer

The number of books printed by the second machine this week is 750 books. Therefore, option C is the correct answer.

Given that, one printing machine printed 500 books in 40 hours this week. A second printing machine printed for 30 hours this week but printed books at twice the hourly rate of the first machine.

We need to find how many books did the second machine print this week.

What is the unitary method?

The unitary method is a process by which we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit. It is a method that we use for most of the calculations in math.

The number of books printed by the second machine this week is 750 books.

Since the first printing machine printed 500 books in 40 hours this week, then the hourly rate will be:

= 500/40

= 12.5 books per hour.

Since the second machine printed at twice the hourly rate of the first one, this will be:

= 12.5 × 2 = 25 books per hour

Since the second machine printed for 30 hours, the total books will be:

= 30 × 25

= 750 books.

The number of books printed by the second machine this week is 750 books. Therefore, option C is the correct answer.
