What is the value of s?
0.7(3s+4)−1.1s=7.9
Enter the answer as a decimal in the box.
The value of s from the equation 0.7(3s+4)−1.1s = 7.9 is 5.1.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
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.
We have,
Equation:0.7(3s+4)−1.1s=7.9
Now, solving equation for s we get
2.1 s + 2.8 - 1.1 s = 7.9
1 s = 7.9- 2.8
s = 5.1
Thus, the value of s is 5.1

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

the formula for the perimeter of a rectangle is P=2l, + 2w, where l is the length and w is the width. A rectangle has a perimeter of 24 inches. Find it's dimensions if it's length is 3 inches greater than it's width.
The dimensions of the rectangle are 7.5 inches and 4.5 inches, or w = 4.5 inches and l = 7.5 inches if the perimeter of a rectangle is P=2l, + 2w.
What is the area of the rectangle?It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
Rectangle area = length x width
The rectangle can be defined as the two-dimensional geometry in which the angle between the adjacent sides is 90 degrees. It is a type of quadrilateral.
P = 24 inches
l = 3 + w
P = 2l + 2w
24 = 2(3 + w) + 2w
24 = 6 + 2w + 2w
24 = 6 + 4w
24 - 6 = 4w
18 = 4w
w = 4.5 inches
l = 3 + 4.5 = 7.5 inches
Thus, the dimensions of the rectangle are 7.5 inches and 4.5 inches, or w = 4.5 inches and l = 7.5 inches if the perimeter of a rectangle is P=2l, + 2w.

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.

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.

Step-by-step explanation:
Monique needs to buy a baseball for $20, a soccer ball for $15, and a set of tennis balls for $12. Monique has a coupon that gives her a discount of x percent on a baseball. She has a second coupon that gives her a discount of y percent on a set of tennis balls. The third coupon gives her a discount of z percent on her total purchase. She cannot combine the coupon for the total purchase with the other two coupons. These expressions give both possibilities for the total cost of Monique's purchase after the coupons are applied, the variables represent the percentages as decimals. (1−x)20+(1−y)12+15 (1−z)(20+15+12) Which part of the expression represents the price of the set of tennis balls after a coupon was applied directly to them?
a.)12
b.)12(1−y)
c.)20 + 15 + 12
d.)20(1−x)
Answer:
[tex]12(1-y)[/tex] represents the price of the set of tennis balls after a coupon was applied.
Step-by-step explanation:
Monique needs to buy a baseball for $20, a soccer ball for $15, and a set of tennis balls for $12.
In the given expression, [tex](1-x)20+(1-y)12+15[/tex] ; [tex](1-y)12[/tex] represents the price of the set of tennis balls after a coupon was applied.
Because the second coupon gives her a discount of y percent on a set of tennis balls and the cost of the set is $12.
