I hope this helps
This year, the sum of your ages is 2k - y. Next year, the sum of your ages will be 2k - y + 2, and the difference in your ages will remain y.
Explanation:If you are k years old and your daughter is y years younger, then your daughter's age is 'k - y'. The sum of your current ages is k + (k - y), which simplifies to 2k - y.
Next year, both of you will be one year older. Therefore, the sum of your ages next year would be '(k + 1) + (k - y + 1)', which simplifies to 2k - y + 2.
The difference in your ages next year would still be 'y' because the ages increase uniformly and the difference between your ages doesn't change.

Haley's car gets at least 17 miles per gallon. If she plans a trip that is 250 miles, what is the minimum number of gallons she'll need?
Answer:
15 gallons
Step-by-step explanation:
Hayley begins solving this problem by combining like terms. 3x + 5x = 10 Which problem requires the same strategy (combining like terms)? A) 5x=20 B) 3(x + 5) = 20 C) x ÷ 4= 30 D) 3x - 2x = 10
Answer:
D) 3x - 2x = 10
Explanation:
To combine like terms, you add or subtract terms that have the same variables and exponents. In the problem we are given, 3x and 5x are like terms; we would add them together and then continue solving.
In choice A, there are no like terms to combine.
In choice B, we would use the distributive property; after that, there are no like terms to combine.
In choice C, we would cancel the 4; there are no like terms to combine.
Choice D has two like terms, 3x and 2x. We would subtract them and then continue solving.

An airplane takes 4 hours to travel a distance of 2600 miles with the wind. The return trip takes 5 hours against the wind. Find the speed of the plane in still air and the speed of the wind.
The speed of the plane in still air = 585 mph
and the speed of the wind = 65 mph
What is speed?
"It is the distance covered per unit time."
What is the formula of speed?
"speed = distance/time"
For given question,
Let, the speed of the airplane in still air = x mph
and the speed of the wind = y mph
So, the speed of the airplane with the wind = (x + y) mph
and the speed of the airplane against the wind = (x - y) mph
Here, the distance (d) = 2600 miles
An airplane takes 4 hours to travel a distance of 2600 miles with the wind.
[tex]\Rightarrow x+y=\frac{2600}{4} \\\\\Rightarrow x+y=650~~~~~~~~~~.........................(i)[/tex]
The return trip takes 5 hours against the wind.
This means, an airplane takes 5 hours to travel a distance of 2600 miles against the wind.
[tex]\Rightarrow x-y=\frac{2600}{5}\\\\ \Rightarrow x-y=520~~~~~~~~~~............................(ii)[/tex]
From equation (ii),
x = 520 + y ........................(iii)
Substitute this value in equation (i),
⇒ (520 + y) + y = 650
⇒ 2y = 650 - 520
⇒ 2y = 130
⇒ y = 65 mph
Substitute the value of y in equation (iii),
⇒ x = 520 + y
⇒ x = 520 + 65
⇒ x = 585 mph
Therefore, the speed of the plane in still air = 585 mph
and the speed of the wind = 65 mph

Mulch to cover a rectangular garden costs $48. Mulch is needed to cover a larger, similar garden. The ratio of dimentions is 2:3. How much would it cost to cover the larger garden?
A) $288
B) $192
C) $72
D) $108
The cost of covering the larger garden is $192. So option (b) is correct.
To solve this problem, let's first find the dimensions of the larger garden.
Given that the ratio of dimensions between the two gardens is 2:3, let's assume the dimensions of the smaller garden are 2x and 3x, where x is a common factor.
So, the smaller garden's area is (2x) * (3x) = 6x².
Now, let's find the area of the larger garden. Since the ratio of dimensions is 2:3, the dimensions are 2(2x) and 3(2x), which are 4x and 6x.
Thus, the larger garden's area is (4x) * (6x) = 24x².
Now, since the cost of mulch is directly proportional to the area, we can set up a proportion to find the cost.
(6x²) / (24x²) = $48 / Cost of covering the larger garden
Solving for the cost of covering the larger garden:
Cost of covering the larger garden = ($48 * 24x²) / (6x²)
= $192
So, the correct answer is B) $192.
