Answer:
The given equation in slope intercept form is
226.50 = 7.5 (25) + 39
Step-by-step explanation:
The SLOPE INTERCEPT form of a equation is y = m x + c
The per hour cost for rental of boat = $25 per hour
Let us assume the one time cleaning charge = $ k
The boat is booked from 11 am : 6 : 30 pm
So, the number of hours boat was used = 7 . 5 hours
Hence, the cost for engaging boat for 7.5 hours
= 7.5 (cost per hour ) = 7.5( $25) = $187 . 5
Total amount paid by the family = $226. 50 = Fixed cleaning charge + rate for 7.5 hours
⇒The cleaning fee paid by the family = $226. 50 - $187 . 5 = $39
According to question:
Total amount paid = Number of hour x (cost per hour ) + Cleaning fee
Hence, the given equation in slope intercept form is
226.50 = 7.5 ($25) + $39
I think that Devon swam at least 35 minutes each day for 5 days because if he exercised 225 minutes and each day he walked for 10 minutes then if you divide 225 by 5 you get 45 so every day he exercised 45 minutes and since he walked for 10 minutes you subtract 10 from 45 which gives you 35 so he swam for 35 minutes.
Potatoes: $2.52 / 4.5lbs = $0.56 / lb.
Broccoli: $7.75 / 2.5lbs = $3.1 / lb
Pears: $2.45 / 2.5lbs = $0.98 / lb
<span>Number line refers to a mathematical process of
solving the equation with the use of lines.
=> 235 + 123
Starting from 0 you count 1 up to 235. Then starting from 235 you additionally
count another 123.
Then from zero start counting the total number to the line you stopped when
adding 123 to 235.
This simply equals to
=> 235 + 123
=> 358.

Answer:
- addition property of equality
- integers are closed to addition
- identity element
- multiplication property of equality
- commutative property of multiplication; reals are closed to multiplication; identity element
Step-by-step explanation:
<u>Given</u>:
c/2 -5 = 7
Step 1: c/2 -5 +5 = 7 +5
Step 2: c/2 +0 = 12
Step 3: c/2 = 12
Step 4: 2(c/2) = 12(2)
Step 5: c = 24
<u>Find</u>:
The property that justifies each step of the solution.
<u>Solution</u>:
Step 1: addition property of equality (lets you add the same to both sides)
Step 2: integers are closed to addition
Step 3: identity property of addition (adding 0 changes nothing)
Step 4: multiplication property of equality
Step 5: closure of real numbers to multiplication; identity property of multiplication

It is hard to say what "property" you want to claim when you simplify an arithmetic expression. Above, we have used the property that the sets of integers and real numbers are closed to addition and multiplication. That is, adding or multiplying real numbers gives a real number.
In Step 5, we can rearrange 2(c/2) to c(2/2) using the commutative property of multiplication. 2/2=1, and c×1 = c. The latter is due to the identity element for multiplication: multiplying by 1 changes nothing.
Apart from the arithmetic, the other properties used are properties of equality. Those let you perform any operation on an equation, as long as you do it to both sides of the equation. The operations we have performed in this fashion are adding 5 and multiplying by 2.
