a rectangular sandbox has a width of 15 ft and a length of X feet which expression represents the perimeter of the sandbox ​

Answer:

1.)21 2.)9

Step-by-step explanation:

You replace each with the number given so in the first one you do 3+6*3 to get 21 and in the second one you do (4-1)^2 or 3^2 or 9

Answer:

21,9

Step-by-step explanation:

Given :

Miki has 104 nickels and 88 dimes. She wants to divide her coins into groups where each group has the same number of nickels and the same number of dimes.

There were 216,000 cars sold last year.

To Find :

Equation that can be used to find the number of trucks, t, sold last year.

Solution :

Let , number of truck sold is t and number of car sold is c.

It is given that the number of cars sold was 39,000 more than three times the number of trucks sold.

So ,

[tex]c=3t+39000\\\\t=\dfrac{c-39000}{3}[/tex]

Putting value of c = 216000 in above equation , we get :

[tex]t=\dfrac{c-39000}{3}\\\\t=\dfrac{216000-39000}{3}\\\\t=59000[/tex]

Hence , this is the required solution .

​

An equation is formed of two equal expressions. An equation that can be used to find the number of trucks, t is 216,000 = 39,000 + 3t.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given that in the Last year, the number of cars sold was 39,000 more than three times the number of trucks sold. Therefore, we can write,

Number of cars sold = 39,000 + 3 times the number of trucks sold

Number of cars sold = 39,000 + 3t

where t represents the number of trucks sold.

Given that number of cars sold is 216,000. Therefore, the equation can be solved for t as shown below.

216,000 = 39,000 + 3t

216,000 - 39,000 = 3t

3t = 177,000

t = 177,000 / 3

t = 59,000

Hence, an equation that can be used to find the number of trucks, t is 216,000 = 39,000 + 3t.

Jen's pace is approximately 13 minutes per mile.

To calculate Jen's pace, we need to determine the time it took her to run 1 mile.

Jen ran 9 miles in 117 minutes, so we divide the total time by the number of miles:

Pace = Total time / Number of miles

Pace = 117 minutes / 9 miles

To simplify the pace, we can convert 117 minutes into hours by dividing it by 60:

Pace = (117 minutes / 60) hours / 9 miles

Pace ≈ 1.95 hours / 9 miles

Now, to find the pace in minutes per mile, we can convert 1.95 hours to minutes by multiplying it by 60:

Pace ≈ (1.95 hours × 60) minutes / 9 miles

Pace ≈ 117 minutes / 9 miles

Therefore, Jen's pace is approximately 13 minutes per mile.

Answer:

41 miles per hour

Step-by-step explanation:

This is a fraction equal to

41 miles ÷ 1 gallon

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 1

41 miles ÷ 1

1 gallon ÷ 1  

= 41 miles per gallon

Draw one whole fraction bar. Next, draw 6 equal bars under it, since you are dividing by sixths. Then draw a twelfths fraction bar with 2 twelfths for each sixth bar. Above the twelfths bar, circle groups of 4 sixths. There is one group of 4/6 with 1/6 remaining. Since 1/6 is 1/4 of 4/6, the quotient is 1 1/4.

5 is number which is a factor of 10 but not a multiple of 2

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We need to find a number which is a factor of 10 but not a multiple of 2

10/2 = 5

however,

2 x 2.5 = 5

Since it doesn't work, cannot have decimals.

Therefore, 5 is your answer

[tex]u=b-ak[/tex]

In our first step, we will flip the equation:

[tex]-ak+b=u[/tex]

Now add -b to both sides:

[tex]-ak+b+-b=u+-b\\-ak=-b+u[/tex]

In our last step, we will divide both sides by -k:
