subtraction addition is commutative for rational numbers Class 8
LHS means left-hand side of the equation and RHS means right-hand side of the equation
3c(-5) = (-5)3c
The LHS of the above expression can also be written as 3 * c * (-1) * 5
The RHS of the above expression can also be written as (-1) * 5 * 3 * c
Since, this expression involved multiplication, it will definitely represent a multiplicative property. Since the order of the numbers that are being multiplied has been changed between LHS and RHS, and it is yielding the same result, it indicates that this is the commutative property of multiplication. This property states that a group of numbers can be multiplied in any order. Hence, the answer is C.
8+3.4=3.4+8
In the above, the order of the numbers being added has been changed across RHS and LHS, but is yielding the same result, it is representing the commutative property of addition. This property states that a group of numbers can be added in any order. Hence, the correct answer is C.

The easiest way to do this is to convert all the fractions into minutes
So, she would've spent 1 hour and 30 minutes on her homework and 40 minutes on her telephone. If you add those amounts up, you get 2 hours and 10 minutes. Since she goes to bed 3 hours after dinner, and 2 hours and 10 minutes have gone by, you do 3 hours - 2 hours 10 minutes and you get 50 minutes.

Answer:
1: 65 in^2
2. 55 ft^2
Step-by-step explanation:
1. First you have to find the area of the trapezoid using the formula (a+b)h/2 where a= 10, b=15, and h=8. The answer will be 100. Then subtract the area of the square inside, which is 35. The final answer is 65.
2. Subtract from the dimensions of the landscape to find the dimensions of the patio. The length of the patio is 11 ft and the width is 5 ft. Therefore, the area is 55 ft^2
Answer:
Alright, helping you because I feel bad. 1) 76 in. 2) 24 in.
Step-by-step explanation:
1. [tex]A= \frac{a+b}{2} h[/tex] a= base b= base h= height Plug in the numbers, [tex](\frac{10+15}{2} ) 8= 100[/tex], but we still need to subtract the area of the un-shaded region (5×2)+(7×2)= 24
100-24= 76
2. Find the area of both landscaping rectangles, including the patio bit.
(14×2)+(8×2)=
28+16=
44in. The two rectangles are the same size, so they both have an equal area. Now we find the area of just the patio spot, W= (8-3)×2 L= (14-3)×2 W= 10 L= 22 A=32 in.
Now, we multiply by two, since we counted it twice, 64 in.
Finally, subtract 64 from the the sum of the two areas from the landscape rectangles, 88-64= 24 in.

A teacher purchased 20 calculators and 10 measuring tapes for her class and paid $495. Later, she realized that she didn't order enough supplies. She placed another order of 8 of the same calculators and 1 more of the same measure tape and paid $178.50.The system represents the situation
`20c+10m=495`
`8c+1m=178.50`
Find the cost of one calculator and the cost of one measure tape using one of our methods of solving systems.
Answer:
Equations are
20c + 10m = 495..............(1)
8c + 1m = 178.5.................(2)
Now , equation (2) * 10 = 80c + 10m = 1785...........(3)
So, Eq. (3) - Eq(1) =
80c + 10m - 20c - 10m = 1785 - 495
60c = 1290
c= 21.5
********************************************************
Now place the value of c in Eq (2)
So , m =6.5

If the length of the longest side of the rectangle is 20cm find the shaded area to the nearest hundredth
Answer:
Step-by-step explanation:
diameter of each circle = 20/2 = 10 cm
rectangle is 20 cm by 10 cm
area of rectangle = 20×10 = 200 cm²
radius of each circle = 10/2 = 5 cm
area of each circle = πr² = 25π cm²
shaded area = 200 - 2(25π) = 200 - 50π =42.92 cm²

w is directly proportional to u if w=5 when u=3,find u when w is =2/7
Answer:
u = 6/35
Step-by-step explanation:
w = k * u
w = ku
Where
k = constant of proportionality
if w=5 when u= 3
w = ku
5 = k * 3
5 = 3k
k = 5/3
find u when w is =2/7
w = ku
2/7 = 5/3 * U
2/7 = 5/3u
u = 2/7 ÷ 5/3
= 2/7 × 3/5
= (2*3)/(7*5)
= 6/35
u = 6/35
