Describe how to use the estimated difference to figure out if the difference in ERAs you found is reasonable.
Answer in 3 complete sentences.
Answer:
Perform the actual multiplication problem either by hand or with a calculator. In this example, students would multiply 21 times 31 to get 651. Subtract the smaller number from the larger one to check for reasonableness. In this example, you would subtract 600 from 651 to get 51.

Robert earned $10, which was 4 less than twice what Eric earned. How much money
did Eric earn?
In a complete sentence, state the correct equation for the scenario.
Identify and define your variable. Then, using the correct vocabulary, and math
process, explain how to accurately solve the problem. Lastly, In a complete sentence
define your answer.
Answer:
$7
Step-by-step explanation:
Robert = $10 or 2x-4
Eric = x (variable), 2x-4=10 (twice minus 4)
Now just manage the equation
2x-4=10 (substitute by adding 4 to both sides)
2x = 4 + 10
2x =14 (substitute by diving by 2 getting rid of x2)
x = 14/2
x = 7
Eric earnt 7 dollars.

A biking track has a length of 0.9 miles . How long is this in feet ?
First fill in the blank on the left side of the equation using one of the ratios. Then write your answer on the right side of the equation.
The biking track of 0.9 miles is 4752 feet long.
Length of the biking track = 0.9miles
What is the relation between mile and foot?We know that 1 mile equals 5280 feet or the length (in feet) is equal to the miles multiplied by 5,280.
The length of the biking track = 0.9miles
So, The length of the biking track(in feet) = 5280*0.9 feet
The length of the biking track(in feet) = 4752 feet.
Therefore, the biking track of 0.9 miles is 4752 feet long.

Answer:
11/20
Step-by-step explanation:
Answer:
3/5
Step-by-step explanation:
Since both 15/20 and 3/20 have a common denominator you just subtract 3 from 15 and you get 12/20
Since both sides can be further divided by 4, you get 12÷4/20÷4 which equals

Use additive inverses and their properties to find equivalent expressions.
Answer:
The first box goes in the first column
2nd box goes in the second column
3rd box goes in the first column
4th box goes in the second
Step-by-step explanation:
Equivalent expressions for the given expressions in the boxes:
box 1: 3 - 5 and -5 - 3
box 2: 5 - 3 and -3 - 5
To find equivalent expressions using additive inverses, we need to understand that the additive inverse of any number 'a' is the number that, when added to 'a', results in zero. The additive inverse of 'a' is denoted as '-a'.
Let's use this property to find equivalent expressions for the given expressions:
1. For the expression 3 + (-5):
The additive inverse of -5 is 5.
So, 3 + (-5) is equivalent to 3 - 5.
Insert this expression in box 1: 3 - 5
2. For the expression 5 + (-3):
The additive inverse of -3 is 3.
So, 5 + (-3) is equivalent to 5 - 3.
Insert this expression in box 2: 5 - 3
3. For the expression -5 + 3:
The additive inverse of 3 is -3.
So, -5 + 3 is equivalent to -5 - (-3).
But remember, a double negative is equivalent to a positive, so -(-3) is just 3.
Insert this expression in box 1: -5 - 3
4. For the expression -3 + 5:
The additive inverse of 5 is -5.
So, -3 + 5 is equivalent to -3 - (-5).
Again, a double negative is equivalent to a positive, so -(-5) is just 5.
Insert this expression in box 2: -3 - 5

And , I = 2000 rt ….(i)
Now,
Since, The invested amount = $2000
⇒ Interest ‘I’ = $2160 - $2000
= $160
Time ‘t’ = 2 years
Substituting these values into;
⇒ 160 = (2000 x 2) r
⇒ r = 0.04

Will works at a shoe store. For every 2 pairs of striped shoes he sells, he sells 3 pairs of neon shoes. Will sold 12 pairs of striped shoes. How many pairs of neon shoes did he sell?
Answer: 18 pairs of neon shoes
Step-by-step explanation: It's a ratio.
2/3 = 12/x. Cross Multiply
2x =12(3). 2x=36 Divide by 2
x = 18
The required number of pairs of neon shoes sold is 18 corresponding to 12 striped shoes.
Given that,
For every 2 pairs of striped shoes he sells, he sells 3 pairs of neon shoes. when selling 12 pairs of striped shoes. How many pairs of neon shoes did he sell is to be determined.
The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
Let the number of neon shoes for the corresponding 12 pairs of striped shoes be x,
According to the question,
2 / 3 = 12 / x
x = 36 / 2
x = 18
Thus, the required number of pairs of neon shoes sold is 18 corresponding to 12 striped shoes.
