Kayaks rent for $35 per day. Write an expression using the Distributive Property that can help you find the cost in dollars of renting 3 kayaks for a day.

Answers

Answer 1
Answer:

Answer:

Unit rate defined as the rates are expressed as a quantity 1 such as 4 miles per hour or 3 meter per seconds.

As per the given statement:

Kayaks rent for $35 per day.

⇒Unit rate per day = $35

We have to write an expression that can help you to find the cost in dollars of renting 3 kayaks for a day:

Cost in dollars for 3 kayaks for a day = $ 3 * 35

The Distributive property says that:

a\cdot (b+c) = a\cdot b+ a\cdot c

we can write 35 as:  30 + 5

then;

3 * 35 = 3 * (30+5) =(3 * 30)+ (3 * 5) = 90 + 15 = \$105

Therefore, a expression that can help you to find the cost in dollars of renting 3 kayaks for a day is (3 * 30)+ (3 * 5)


Answer 2
Answer: 5 x 3 = 15
30 x 3 = 90 
15+90=105
so that person paid $105 for that day

Mila thinks 1/2 is equivalent to 2/3 and to 3/6

Answers

Hi

1/2 = (1×3)/(2×3) = 3/6

But 

1/2 ≠ 2/3
Mila is right and wrong because 1/2 isn't equal to 2/3 but, 1/2 is equal to 3/6.

How do you model a decimal using a fraction

Answers

Okie dokie, 
When converting a decimal, you use the place the decimal is in...
Let's review the places: tenths, hundredths, thousandths, etc.
You look at the last number to determine what place you're using!
-------------------
Now here's an example for the tenths place:
.5
it's in the tenths place, right? so put it over that number (with no decimal) over a 10.
(mobile) 5/10 or (5)/(10)
Now, decide if you can simplify. You can! 5/10 simplifies down to 1/2.
(1)/(2) is your answer!
--------
Example for the hundredths place:
.26
the last number is in the hundredths place, so put the number (without a decimal) over 100!
26/100 or (26)/(100)
You can simplify this!
13/50 is your answer!

Calculators can also come in handy!
Good luck!

the number of girls and boys in math class totals 27. how many girls are there if the of girls is 3 more than twice the number boys?

Answers

Answer: 15 girls

Step-by-step explanation:

27 - 3 = 24

24/2 = 12

12 boys

12 + 3 = 15

15 girls

15+ 12 = 27

Answer: 15

Step-by-step explanation: Personally, I would try finding the number of boys first and then subtract the number of total students by the number of boys. To find the boys, you need to subtract three from 27 since those 3 are girls which leaves you with 24. It says there is half the number of boys than girls when you subtract 3 so 24 divided by 2 is 12. The number of boys is 12 so now all you have left to do is subtract 27-12 to find the number of girls, which is 15. I hope this helped you and sorry if it’s really long :)
