b. 113 + 154 = 267 is a way of estimation to check 267 - 154 = 113.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given a numerical expression 267 - 154 = 113.
The correct elimination is we must add 154 to both sides to eliminate 154 on LHS and add 154 on RHS.
∴ 267 - 154 = 113 is
267 + 154 - 154 = 113 + 154,
113+154=267

you have scored 7,10,8 , and 9 on four quizzes . write and solve an equation to find the score you need on the fifth quiz so that your mean score is 8
To achieve a mean score of 8 after five quizzes, you would need to score 6 in your fifth quiz, assuming your scores in the first four quizzes were 7, 10, 8, and 9 respectively.
Explanation:Yes, these scores are associated with the subject of mathematics, particularly the branch of math known as statistics. This involves determining how to achieve a desired mean, which in this case is 8, given your previous quiz scores.
The mean score is determined by adding all your quiz scores together and dividing by the total number of quizzes. So for your first four quizzes, the total is 7 + 10 + 8 + 9 = 34. The mean so far is 34 ÷ 4 = 8.5 which is already above our targeted mean of 8.
To achieve a mean of 8 over 5 quizzes, the total of your scores would need to be 8 x 5 = 40. Therefore, the score you would need to get on your fifth quiz would be 40 (the desired total) - 34 (the current total) = 6.

Finding multiples that go into 86 52 18
Find y when x=9 if y varies directly as the square of x, and y=100 when x=5.
Answer:
324
Step-by-step explanation:
Given : y varies directly as the square of x
To Find : Find y when x=9
Solution :
We are given that y varies directly as the square of x
[tex]\Rightarrow y \propto x^2[/tex]
So, [tex]\Rightarrow y= kx^2[/tex] ---1
where k is the constant of proportionality
Now we are also given that y=100 when x=5.
Substitute the values in 1
[tex]100= k(5)^2[/tex]
[tex]100= 25k[/tex]
[tex]\frac{100}{25}=k[/tex]
[tex]4=k[/tex]
So, equation becomes [tex]y= 4x^2[/tex]
Now substitute x= 9
[tex]y= 4(9)^2[/tex]
[tex]y=324[/tex]
Hence The value of y when x is 9 is 324
simplicity the expression (0.4^3)

A seafood restaurant claims an increase of $3,150 over its average profit during a week where it introduced a special of baked clams.
Part 1
If this is true, how much extra profit did it receive per day?
The restaurant received $
450
extra profit per day.
Part 2
If it had, instead, lost $150 per day, how much money would it have lost for the week?
The restaurant would have lost $
1,050
for the week.
Part 3 out of 3
If its total loss was $420 for the week, what was its average daily change?
The restaurant's average daily change was −$
.
Final answer:
The restaurant gained an additional $450 per day with the special item, lost $1,050 if it had lost $150 per day, and an average daily loss of $60 if the total weekly loss was $420.
Explanation:
To calculate the extra profit per day, we divide the total extra profit by the number of days in a week. $3,150 divided by 7 days gives us $450 extra profit per day.
If the restaurant had lost $150 per day instead, we would multiply the daily loss by the number of days in a week. So, $150 times 7 days equals a total loss of $1,050 for the week.
For the last part, if the total loss for the week was $420, to find the average daily change, we divide this amount by 7. Thus, $420 divided by 7 days equals a daily change of -$60.

Lillian bought 2.52 pounds of tomatoes and 1.26 pounds of lettuce to make salad for 18 people. If each person got the same amount of salad , how much salad did each person get?
Answer:
amount of salad by each person = 0.21 pounds
Step-by-step explanation:
Lilian bought 2.52 pounds of tomatoes and 1.26 pounds of lettuce to make salad for 18 people. That means the combined weight in pounds of tomatoes and lettuce is the weight of the salad.
The weight of the salad = 2.52 + 1.26
The weight of the salad = 3.78 pounds
The total weight of the salad is 3.78 pounds . He shared the weight to 18 people and each person collected the same amount.
To find the amount each person got, we divide 3.78 by 18 people.
amount of salad by each person = 3.78/18
amount of salad by each person = 0.21 pounds
