The required expression that represents the average of three test scores is x + y + z / 3. Option C is correct.

The average of the values is the ratio of the total sum of values to the number of values.

Here,
The required average of three test scores,
= sum of the scores/number of scores
= x + y + z / n(x, y, z)
= x + y + z / 3

Thus, the required expression that represents the average of three test scores is x + y + z / 3. Option C is correct.

Answer:

The volume of shipping crate is 32 unit cubes.

Step-by-step explanation:

Given that:

Length of the crate = 4 units

Width of the crate = 2 units

Height of the crate = 4 units

Volume of shipping crate = Length * Width * Height

Volume of the crate = 4 * 2 * 4

Volume of crate = 32 unit cubes.

Hence,

The volume of shipping crate is 32 unit cubes.

Answer:

Answer:

x = 6

Step-by-step explanation:

These two angles make a complementary angle meaning the sum of the angles will be 90°. We can use this information to make an equation to solve for x.

10x + 30 = 90 (Given)

10x = 60 (Subtract 30 on both sides)

x = 6 (Divide 10 on both sides)

Answer:

x = d/5 - $50

Step-by-step explanation:

Basiclly what this sentence is saying that the price d is equal to $250 + 5 prices of staying in a hotel for a night.

If we let "x" be the price per night then we can get the following..

d = $250 + 5x

5x = d - $250

[tex]x = \frac{d - 250}{5}[/tex]

x = d/5 - $50

Answer:

Step-by-step explanation:

Here you go mate

Step 1

2x + y = 11 and x + 3y = 3  Equation/Question

Step 2

x+3y=3  Substitute -2x+11 for y

x+3(-2x+11)=3

Step 3

x+3(-2x+11)=3  simplify

x=6

Step 4

y=-2x+11  Substitute 6 for x

y=-2(6)+11

Step 5

y=-2(6)+11  simplify

y=-1

answer

x=6

y=-1........hope this helps

Answer:

The two will be at the same place in 1/5 of a minute

Step-by-step explanation:

Here, we shall substitute the value 1/2 for x on both sides of the equation

We have this as;

1000(1/5) + 20

= 200+20 = 220

secondly, we have

1,100(1/5) = 220

From the solution, we can see that both sides will be equal and the same amount of distance will have been covered

What this simply mean is that they both will be at the same place in 1/5 of a minute

Answer:

10 gallons of gas.

Step-by-step explanation:

250/9 = how many miles 1 gallon of gas will take

250/9 = 27.78

1 gallon of gas = 27.78 miles

275/27.78 = 9.90 gallons

9.90 gallons round up to 10 gallons

Therefore, Trey would need 10 gallons of gas to drive 275 miles.

Answer:

The correct answer is 9.9 unrounded.
