Answer:

option c is correct

180 cars can they wash in 15 hours

Step-by-step explanation:

Unit rate defined as the rate are expressed as a quantity 1 such as 4 miles per hour or 5 meter per second.

As per the statement:

Some students washed 24 cars in 2 hours

Then by definition of unit rate.

\text{unit rate per hour}=\frac{24}{2} = 12

We have to find how many cars can they wash in 15 hours

⇒\text{Number of cars washed in 15 hours} = \text{Unit rate per hour} \cdot 15

Substitute the given values we have;

\text{Number of cars washed in 15 hours} = 12 \cdot 15

Simplify:

\text{Number of cars washed in 15 hours} = 180

Therefore, 180 cars can they wash in 15 hours

Furkat [3]

Answer:

You would at least a 90 to average out your score to an 84

but I dont know how to get the inequality sorry

I hoped this helped a little

Step-by-step explanation:

Fisrt you will need to find the average of the numbers by adding them up and dividing by 3 ( because there are 3 numbers )

which would give you 81

then you have to get at least above an 81 to make it go higher but you may have to do a little more than that there for 90 is what you need

Solve the system of equations and choose the correct ordered pair.
frez [133]
What I would do:

5x + 10y = 35

Divide everything by 5.

x + 2y = 7

x = 7 - 2y

Now plug "x" into either one of the equations.

2(7-2y) + 5y = 15

14 - 4y + 5y = 15

14 + y = 15

y = 1

Now, solve for x by plugging in y into either one of the equations.

2x + 5y = 15

2x + 5 =15

2x = 10

x = 5

So x is 5 and y is 1.

Check by plugging in the values into the other equation.

5x + 10y = 35

5(5) + 10(1) = 35

25 + 10 = 35

35 = 35

The values are correct so, the answer for this problem is B (5, 1).

A classmate simplifies the expression in exercise 1. is the expression he wrote equivalent to the original expression? explain.
AlladinOne [14]
Excercise 1:

No, this is not simplified fully. The full answer would be <span>−7dk+14d−21k</span>−7, not <span>14d - 9 - 21k - 7dk + 2. So, it is not equivalent.
</span><span>
Excercise 4:
</span><span>7dk (2 - 3 - 1) - 7
</span>
Just multiply 7dk into (2) (-3) and (-1)
you'd get:
<span><span>−<span>14dk</span></span>+</span>−<span>7 after simplifying it fully.
