Answer:

1) x=14

2) n=21/8=2.625

Step-by-step explanation:

1)

So we have the equation:

[tex]\frac{x}{16}-\frac{1}{2}=\frac{3}{8}[/tex]

First, let's remove all the fractions. Multiply both sides by the LCM of 16, 2, and 8, which is 16. So:

[tex]16(\frac{x}{16}-\frac{1}{2})=16(\frac{3}{8})[/tex]

Distribute:

[tex]16(\frac{x}{16})-16(\frac{1}{2})=16(\frac{3}{8})[/tex]

Simplify:

[tex]x-8=6[/tex]

Add 8 to both sides:

[tex]x=14[/tex]

So, the value of x is 14.

2)

We have:

[tex]\frac{3n}{7}-1=\frac{1}{8}[/tex]

Again, let's remove the fractions by multiplying both sides by the LCM of 7 and 8, which is 56. So:

[tex]56(\frac{3n}{7})-56(1)=56(\frac{1}{8})[/tex]

Simplify:

[tex]24n-56=7[/tex]

Add 56 to both sides:

[tex]24n=63[/tex]

Divide both sides by 24:

[tex]n=63/24[/tex]

Reduce:

[tex]n=21/8=2.625[/tex]

And we're done!

round it to a whole number of 100 m witch i think would be 15700 m

Answer:

Its 17 feet and 11 units

Step-by-step explanation:

Answer:

let the earlier temperature be x

then change in temperature is x - 15

-2 + n = -8(1 - 8n) + 6

Distribute the -8

-2 + n = -8 + 64n + 6

Combine like terms.

-2 + n = 64n - 2

Add 2 to both sides and subtract n from both sides.

0 = 63n

Divide both sides by 63

0 = n

Answer:

Step-by-step explanation:

x - 4y = 4

-4y = -x + 4

y = 1/4x - 1

y + 1 = 1/4(x + 8)

y + 1 = 1/4x + 2

y = 1/4x + 1

Answer:

3.75 gallons

Step-by-step explanation:

speed = distance/time

s = d/t

d = st

d = (60 mi/hr) * (75 min) * (1 hour)/(60 min) = 75 miles

In 75 minutes of driving at 60 mph, he drives 75 miles.

fuel economy = distance/volume

volume * fuel economy = distance

volume = distance/(fuel economy)

volume = (75 miles)/(20 miles/gal)

volume = 3.75 gallons

Answer: 3.75 gallons

x = 6

Answer:

The bench costs $425

Step-by-step explanation:

First lets define our variables:

t = garden table

b = bench

Next, we have to use the information to create two formulas. One formula is for the cost of a garden table and a bench. The second is for the cost of the garden table.

t + b = 755

t = b - 95

For the next step, we can solve for be by using the second formula we created and replacing (t) in the first formula:

b - 95 + b = 755

2b - 95 = 755

2b = 850

bench = 425

To find out how much the cost of the cost of the table is, you can plug in the cost of the bench (b) back into the second equation:

t = b - 95

t = 425 - 95

table = 330

Answer:

Rose was wrong because 4 + 11 is not 7; the answer would be 15*F

Step-by-step explanation:

4+11 = 15

hope this helps

Rose is incorrect as the temperature in Mayville that afternoon

(4 + 11)°F = is 15°F not (-4 + 11)°F = 7°F.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, Overnight, the temperature in Mayville was 4°F.

But by the following afternoon, the temperature had risen 11°F.

∴  The temperature in Mayville that afternoon is the sum of the total temperatures which is,

= (4 + 11)°F.

Answer:

-3d = 43-10

-3d = 33

d = 33/-3

d = -11

Answer:

d = 11

Step-by-step explanation:

Simplifying

3d + 10 = 43

Reorder the terms:

10 + 3d = 43

Solving

10 + 3d = 43

Solving for variable 'd'.

Move all terms containing d to the left, all other terms to the right.

Add '-10' to each side of the equation.

10 + -10 + 3d = 43 + -10

Combine like terms: 10 + -10 = 0

0 + 3d = 43 + -10

3d = 43 + -10

Combine like terms: 43 + -10 = 33

3d = 33

Divide each side by '3'.

d = 11

Simplifying

d = 11

It's C

Step-by-step explanation:

The mean number of days employee were sick is 4.43 days.

Option C is correct.

Here,

Given that;

The department manager recorded the number of sick days taken last year by each employee, as shown in the table.

We have to find the mean number of days employee were sick.

What is Mean?

The average of the given numbers is called Mean and is calculated by dividing the sum of given numbers by the total number of numbers.

Now,

In given table;

Number of sick days are,

7, 4, 2, 6, 4, 5, 3

Hence,

Mean number of days employee were sick = [tex]\frac{7+4+2+6+4+5+3}{7}[/tex] [tex]= \frac{31}{7}[/tex][tex]= 4.4285[/tex]

Now, Rounding the number to the nearest hundredth we get;

Mean of number of days employee were sick = 4.43 days

Hence, The mean number of days employee were sick is 4.43 days.

Option C is correct.
