Someone please help. Explain why it might be easier to solve the multiplication problem by changing it from this: 5×98×2 , to this: 5×2×98 . Use a property of multiplication to justify your reasoning.
Answer:
Because it is easy to multiply 5 by 2 which is 10......and then 10 × 98 youbjust have to add 0 to 98.....which will be 980
The multiplication problem can be simplified by the equation A = 5 x 2 x 98 and the value of A = 980
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
A = 5 x 98 x 2
On simplifying , we get
From the associative property , we get
A = ( 5 x 2 ) x 98
where the value of 5 x 2 = 10
So , the multiplication expression is
A = 10 x 98
A = 980
Therefore , the value of A is 980
Hence , the equation is A = 980

An elephant at the zoo lost 24 pounds over 6 months.The elephant lost the same amount of weight each month.Write an integer that represents the change in the elephant's weight each month.
Answer:
He loses 4 pounds which is (-4)
Why?
Because it says that the elephant lost 24 pounds in 6 months which will represent (-24). Then (-24)/6 = (-4)
Therefore, he takes (-4) pounds in his weight each month.

Naomi works in a music shop and earns $42 per day. She earns an extra $2 for each CD she sells. If Naomi wants to earn at least $80 per day, which inequality shows the minimum number of CDs, n, that she should sell?
42 + 2n ≤ 80, so n ≤ 19
42 + 2n ≥ 80, so n ≥ 19
42 + 2n ≥ 80, so n ≥ 36
42 + 2n ≤ 80, so n ≤ 36
A square room has an area of 14,400 square
inches. What is the length of a side of the
room in inches?
Answer:
120 inches
Step-by-step explanation:
The area for formula is [tex]A=l*w[/tex], where A is area, l is the length, and w is the width.
However, since it's square room, you can just multiply the length times itself. This makes the formula [tex]A=l^{2}[/tex].
Now you can substitute 14,400 for A, since that's the area. this brings us to [tex]14400=l^{2}[/tex]. To solve the equation, just find the square root of both sides.
The square root of [tex]l^{2}[/tex] is l.
The square root of 14400 is 120. (I used a calculator for this.)
(BTW, a square root is the number that can be squared to get to a number. For example, the square root of 25 is 5, because 5 times 5 is 25. The square root of 14400 is 120, because 120 times 120 is 14400.)
Answer:
120 INCHES IS THE SIZE OF THE ROOM.
Step-by-step explanation:
120 is the answer because A(Area) = L(Length) x W(Width)
The area for formula is , where A is area, l is the length, and w is the width.
However, since it's square room, you can just multiply the length times itself. This makes the formula .
Now you can substitute 14,400 for A, since that's the area. this brings us to . To solve the equation, just find the square root of both sides.
The square root of is l.
The square root of 14400 is 120. (I used a calculator for this.)
(BTW, a square root is the number that can be squared to get to a number. For example, the square root of 25 is 5, because 5 times 5 is 25. The square root of 14400 is 120, because 120 times 120 is 14400.)

An orchard sells apples in 5.5‐pound bags. The orchard sells 65 bags of apples each day.
How many pounds of apples does the orchard sell in 1 week?
The orchard sells
pounds in 1 week.
Answer:
2502.5 pounds
Step-by-step explanation:
Answer:
2,503 pounds
Step-by-step explanation:
Multiply the amount of bags sold by the number of days within a week.
65 x 7 = 455
In 1 week 455 bags of apples are sold.
The next step is to multiply the total amount of bags sold in 1 week by the pound of 1 bag of apples.
455 x 5.5 = 2,502.5lbs
2,503lbs (rounding to the nearest whole number) of apples are sold in 1 week.
