Answer: 13 (and Sally will always be 3 years older than Jill)
Step-by-step explanation:
Let S and J stand for Sally and Jill's ages. We are told:
(S-5) = (J-5)+3 [Sally is 3 years older than Jill was 5 years ago] The 5 years ago is the reason for the (S-5) and (J-5) expressions.If Jill is 10, how old is Sally?
(S-5) = (J-5)+3
(S-5) = (10-5)+3
S-5 = 8
S = 13
We actually don't really need an equation for solving this, other than the question asks us to write one. It doesn't matter how many years later, since Sally is 3 years older, she will always remain 3 years older, if we ignore the likelihood that the statement doesn't hold true for the period between their actual birthdays.

200 POINTS! PLEASE HELP!!!
You have $75 dollars to spend on side dishes for a party. Pasta salad costs $2.50 a pound and fruit salad costs $3.75 a pound. you must buy at least 5 pounds of pasta salad and 3 pounds of fruit salad. There are 40 people to feed and there needs to be at least a quarter of a pound of each side dish for every guest. You want to be able to buy the most amount of food for the party.
let x = pounds of pasta salad and y = pounds of fruit salad.
The objective function is f=x+y.
The vertices of the feasible region are (5,5) (5,16.6) (25.5,3) and (7,3)
what is the maximum amount of food you should buy?
how much pasta should you buy?
how much fruit salad should you buy?
Answer:
So, I cannot answer the whole question, but I can give you my thought process. SO, since you need to feed 40 people with a quarter of each meal - you would need 10 pounds of each dish. Therefore the information about the "least amount" of each dish is met. As mentioned, x = pounds of pasta salad, while y = pounds of fruit salad. this means x would equal 10 and y would equal 10. In order to find out what it would cost is:
2.50 x 10 = 25 ($25)
3.75 x 10 = 37.5 ($37.50)
the function could possibly be f=10+10?
The maximum amount of food you should buy would be 20 pounds of food, considering you need to have enough for each guest.
You should buy 10 pounds or $25 worth of pasta salad, and 10 pounds, or $37.50 worth of fruit salad.
The Equation of line f is y =4/9x+3/2. line g is perpendicular to f. What is the slope of line g?
Answer:
slope of line g = -9/4
Step-by-step explanation:
Perpendicular lines have negative reciprocal slopes:
m1 × m2 = -1 or [tex]m1 = -\frac{1}{m2}[/tex]
If the slope of line f = 4/9, as given the linear equation, y = 4/9x + 3/2, then the slope of line g must be -9/4. Because if you multiply both slopes, the product will be -1:
Let m1 = slope of line f = 4/9
m2 = slope of line g = -9/4
m1 × m2 = -1
[tex](\frac{4}{9}) (- \frac{9}{4})[/tex] = -1
Therefore, the slope line g = -9/4.

What is the quotient when 8465 is divided by 5?
Answer:
The quotient would be 1693
When 8465 is divided by 5, the quotient is 1693. The quotient of a fraction is the whole number obtained when the fraction is simplified.
What is meant by quotient?The number being divided (in this case, 15) is known as the dividend, and the number being divided by (in this case, 3) is known as the divisor. The quotient exists as the result of the division.The quotient is the result of performing division operations on two numbers. It is essentially the result of the division method. Arithmetic division employs four key terms: divisor, dividend, quotient, and remainder.The quotient is the result of dividing one number by another. For example, if we divide 6 by 3, the result is 2, which is the quotient. The quotient can be either an integer or a decimal.Therefore,
To sum up, 8465/5 = 1693.
It is a whole number with no fractional part.
As division with remainder the result of
= 8465 ÷ 5
= 1693
When 8465 is divided by 5, the quotient is 1693

What is the total total amount of digits you need to number a book of 1150 pages
Step-by-step explanation: When numbering the pages of a book, which has 1,150 pages, we need: 9 one-digit numbers (from 1 – 9);90 two-digit numbers (from 10 – 99);900 three-digit numbers (from 100 – 999);151 four-digit numbers (from 1,000 – 1,150).
The total amount of digits you need to number a book of 1150 pages will be 3493 digits.
What is an arithmetic operation?It is described as the process through which we add, subtract, multiply, and divide numerical values. It has the fundamental operators +, -, and.
There are pages for the digits totaling,
Single digits : (1 - 9) = 9 pages
Double digits : (10 - 99) = 90 pages
Triple digits : (100 - 999) = 900 pages
Four digits : (1000 - 1150) = 151 pages
By summing all digit counts such as, one may determine the total number of digits.
= (9 + 180 + 2700 + 604)
= 3493 digits.
Thus, the total amount of digits you need to number a book of 1150 pages will be 3493 digits.

The volume of a rectangular prism box can be represented by the function V(x) = 2x3 + 5x2 − 3x. If the height of the box is x cm, which of the following can represent the length and width of the container?
The volume of a box is the amount of space in the box.
The expressions that can represent the length and the width are: [tex]\mathbf{(2x - 1)\ and\ (x + 3)}[/tex]
The volume is given as:
[tex]\mathbf{V(x) =2x^3 + 5x^2 - 3x}[/tex]
Divide through by height (i.e x), to get the base area
[tex]\mathbf{A(x) =2x^2 + 5x - 3}[/tex]
Expand
[tex]\mathbf{A(x) =2x^2 + 6x - x - 3}[/tex]
Factorize
[tex]\mathbf{A(x) =2x(x + 3) - 1(x + 3)}[/tex]
Factor out x + 3
[tex]\mathbf{A(x) =(2x - 1) (x + 3)}[/tex]
Hence, the expressions that can represent the length and the width are: [tex]\mathbf{(2x - 1)\ and\ (x + 3)}[/tex]

Step-by-step explanation:
Help!!! Please answer all three of them
Answer:
Step-by-step explanation:
for the first one, solve by using the equation
180 = 43 + (x) + (x + 39)
137= x + x + 39
98 = 2x
x = 49
x + 39 = 88
for the second one, 5 and 7 are vertical angles, which are the two equal angles on opposite ends of an intersection. This means the answer is E.
for the third one, to find the exterior angle, you have to find that last angle inside the triangle. that means subtracting 85 and 65 from 180 to get 30. Now, subtract that 30 from 180 to get the exterior angle c. Straight lines are 180 degrees, so by finding that other angle and subtracting it from the total 180, you find the exterior angle. The exterior angle c is 150 degrees.
