Answer:

Equation: 810= (90 + 24y)

y = 30 hours

Step-by-step explanation:

Given:

Site visit = $45 per site

cost per hour worked = $24

for each work site, the total amount of money earned

= site visit fee + cost for working

But the question mentions TWO sites, hence there will be two site visits. Therefore for TWO sites, we have to account for TWO site visit fee.

Therefore for TWO sites, the total amount of money earned

= site 1 visit fee + site 2 visit fee + cost for working

= (2 x site visit fee) +  cost for working  ------ Equation 1

We are further given that we worked y hours at the hourly work rate of $24 per hour.

Hence the cost for working

= y hours x hourly rate

= y   x   $24

= $24y   (substituting this into equation 1 above)

for TWO sites, the total amount of money earned

= (2 x site visit fee) +  cost for working

= (2 x $45) +  $24y

= $90 + $24y

= $(90 + 24y)

We are also given that we have to earn $810 for two sites, hence

810 = 90 + 24y    

810 - 90 = 24y

24y = 720

y = 720/24

y = 30 hours

Cross multiply

That's

7x = 3( 2x + 3)

Multiply the terms

That's

7x = 6x + 9

Subtract 6x from both sides

We have

Step-by-step explanation:

Given that:

A football team lost 5 yards on each of 3 plays

Using a number line we could show the loss in yard after each play. With a loss of 5 yards after each play, there will be a total of:

(Number of plays * yards lost) = (3 * 5) = 15 yards

The attached picture shows a number line moving a distance of 5 yards to the left ( negative direction) after each play after which it arrives at a total loss of 15 yards after the third play.

Stu had quite a collection of baseball cards. One day he decided to give half of them to his brother Seth. Then he gave one-third of what he had left to a friend. Then he gave half of what was left to another friend. Stu now has 50 baseball cards. How many did he start with? It seems that I should work

let Stu have x cards

he gave half to seth

so he had x/2 cards

He had x/2 he gave 1/3 of x/2 to a friend

=x/6.

Now he had x/2 - x/6 = x/3 with him balance

1/2 of x/3 he gave to another friend =x/6

Balance he had was x/3 - x/6 = x/6

x/6 = 50

multiply by 6

x= 300

Answer:

Now he had x/2 - x/6 = x/3 with him balance

1/2 of x/3 he gave to another friend =x/6

Balance he had was x/3 - x/6 = x/6

x/6 = 50

multiply by 6

x= 300

Step-by-step explanation:

The equation of line A:

y - 1 = 0.5x - 3

y = 0.5x - 2. Hence its gradient is 0.5.

For line B, its y intercept is -8, so y = mx - 8.

When x = -4, y = -4m - 8 = 0 as shown in the graph. This means that m = -2.

So the equation of line B:

y = -2x - 8. Its gradient is -2.

Since |-2| > |0.5|, line B is steeper than line A.

The slope of the line A(1/2) > slope of line B(2).

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

Take Points from the graph as (-4, 0) and (0, 8)

so, the slope is

m = (8-0)(0-(-4))

m = 8/ 4

m = 2

So, the slope- intercept form

y- 0 = 2(x- (-4))

y= 2x + 8

Hence, the slope of the line A(1/2) > slope of line B(2).

Answer:

[tex]-\frac{1}{12}[/tex]

Step-by-step explanation:

So we have the expression:

[tex]\frac{2}{6}-\frac{5}{12}[/tex]

To subtract, we want to have a common denominator. So, let's find a common denominator by using the LCM.

The LCM of 6 and 12 is 12.

Since the second term is already 12, let's multiply the first term by 2 to get its denominator to be 12:

[tex]=(\frac{2}{2})\frac{2}{6}-\frac{5}{12}[/tex]

Multiply:

[tex]=\frac{4}{12}-\frac{5}{12}[/tex]

Now, we can combine the fractions:

[tex]=\frac{4-5}{12}[/tex]

Subtract:

[tex]=\frac{-1}{12}[/tex]

And we are done!

Answer:

x = -5

Step-by-step explanation:

Original Equation: 2x + 3 = -7

Subtract 3 from both sides:

2x + 3 - 3 = -7 - 3

Simplify:

2x = -10

Divide both sides by 2:

[tex] \frac{2x}{2} = \frac{ - 10}{2} [/tex]

Simplify:

x = -5

Answer:

x = 4

Step-by-step explanation:

Given the 2 equations

2x - y = 11 → (1)

x + 3y = - 5 → (2)

Multiply (1) by 3 and add to (2) to eliminate the y- term

6x - 3y = 33 → (3)

Add (2) and (3) term by term to eliminate y, that is

7x = 28 ( divide both sides by 7 )

Answer:

f (4) = 3(4) - 12

Step-by-step explanation:

if x = 4 just substitute the x for the 4 .

f(x) = 3x - 12

f(4) = 3 (4) - 12

f(4) = 12 - 12

and that cancels itself out.

Answer:

The number of peanuts that will be needed to make all the sandwiches a child will eat by graduation  is approximately 141,667 peanuts

Step-by-step explanation:

The number of peanut butter sandwiches that an average American child will eat by the time she graduates from high school = 1500 peanut butter sandwiches

The number of sandwich taken every four days = 1 sandwich

The number of peanuts required to make 18-oz jar of peanut butter = 850 peanuts

The amount of peanut butter in an average sandwich = Two ounces

Therefore, we have by the time of graduation;

Each American child will have taken 1500 sandwiches

The 1500 sandwiches will have = 1500 × 2 ounce = 3,000 ounces of peanut butter

The number of 18-oz jars of peanut butter that will contain up to 3000-oz of peanut butter = 3000-oz/(18-oz) = 166.67 Jars

The number of peanuts required to make the 166.67 Jars of peanut butter = 850 peanuts/jar ×  166.67 Jars = 141666.67 ≈ 141,667 peanuts

The number of peanuts that will be needed to make all the sandwiches a child will eat by graduation  ≈ 141,667 peanuts.

I think Mr. Han is around the 60 or 70 age.

I am really sorry that I couldn't answer this problem.  Try starting with 21 and multiply that by 3.  To check if you can do it, add 43 to the number you multiply 3 with.  Again, i am really sorry that i only wrote a hint.  Good luck finding the answer!

Now the age of Mr. Han will be 54 years old.

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

Let x be the age of Mr. Han and y be the age of Alice.

She found that Han is 36 years older than her. Then the equation will be

x = y + 36     ...1

7 years later, Han will be 3 times as old as her. Then the equation will be

(x + 7) = 3(y + 7)

x = 3y + 14   ...2

From equations 1 and 2, we have

3y + 14 = y + 36

2y = 22

y = 11

Then the value of x will be

x = 11 + 36

x = 47

The age of Mr. Han will be

⇒ 47 + 7

⇒ 54

Now the age of Mr. Han will be 54 years old.
