Answer:
$24.09
Step-by-step explanation:
you do 984.20-381.80=602.4
then divide 602.4 by 1/4
which 1/4=25.
then you get $24.09
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.
Answer:
Step-by-step explanation:
Total money = $600
Bicycle cost = $253.98
3 bicycle reflector = 3×$7.5 =$22.5
Bicycle helmet = $42.36
Total money spent will be equal to the = $(253.98+22.5+42.36)
= $318.84
Amount remaining = $(600-318.84)
= $281.16
The number of outfit he can get at $78.12 = $281.16/78.12 = 3.60
He can get 3 outfit and have $0.60
Left
For this case we have the following function:
We can rewrite the function to identify the zeros of it.
When rewriting the function factoring we have:
Therefore, the zeros of the function are:
Thus, the graph that contains intersections on the x axis in the points mentioned, will be the graph of the function.
Answer:
See attached image.
1 gal = 400 ft²
2 3/8 gal = ? ft²
to solve, use similar ratios with units gal/ft² and compare
(1)/(400) = (2 3/8)/(x)
*multiply both sides by (x) and divide both sides by (1)/(400), you get:
x = (400)*(2 3/8)/(1) = 400*(2 3/8) = 400*2 + 400*3/8 = 800 + 150 = 950 ft²
<u><em>answer is 950 ft²</em></u>
