Jerry has a new job and earns a salary of $45,000. Victoria has a new job and earns a salary of $54,000. Jerry will receive a salary increase of $2,500 per year, and Victoria will receive a salary increase of $1,500 per year. Which equation can be used to find x, the number of years it will take Jerry to earn the same salary as Victoria?
A.) 45,000x + 2,500x = 54,000x + 1,500x
B.) 45,000x +2,500 = 54,000x + 1,500
C.) 45,000 + 2,500x = 54,000 + 1,500x

The vertex of the parabola described by the equation 3y=2x^2-16x+18 is (m,n). What is m+n?
Answers
Answer:
the aswer is 32
Step-by-step explanation:
The vertex of the parabola described by the equation 3y=2x^2-16x+18 is (m,n). the sum of m + n is 178/27.
To find the vertex of the parabola described by the equation 3y = 2x^2 - 16x + 18, we first need to put the equation in the standard form of a parabola, which is y = a(x - h)^2 + k, where (h, k) represents the vertex.
Let's begin by dividing the entire equation by 3 to simplify it:
y = (2/3)x^2 - (16/3)x + 6
Now, we need to complete the square to rewrite the equation in the form y = a(x - h)^2 + k:
y = (2/3)(x^2 - (8/3)x) + 6
Next, we need to find the value that completes the square for the expression inside the parentheses. To do that, we take half of the coefficient of x and square it:
(8/3) / 2 = 4/3
(4/3)^2 = 16/9
Now, we add and subtract 16/9 inside the parentheses:
y = (2/3)(x^2 - (8/3)x + 16/9 - 16/9) + 6
Now, we group the first three terms and factor the perfect square trinomial:
y = (2/3)((x - 4/3)^2 - 16/9) + 6
Next, distribute the (2/3):
y = (2/3)(x - 4/3)^2 - (2/3)(16/9) + 6
Now, simplify:
y = (2/3)(x - 4/3)^2 - (32/27) + 6
Finally, bring everything together:
y = (2/3)(x - 4/3)^2 + (142/27)
Now we can see that the vertex of the parabola is at the point (h, k) = (4/3, 142/27).
To find m + n, we simply add the x-coordinate (h) and the y-coordinate (k):
m + n = 4/3 + 142/27
To add these fractions, we need to find a common denominator, which is 27. Convert 4/3 to have a denominator of 27:
4/3 = (4/3) * (9/9) = 36/27
Now we can add the fractions:
m + n = 36/27 + 142/27
m + n = (36 + 142)/27
m + n = 178/27

Since all the six balls have same weight and the total weight is given as 273g, then weight of one ball will be
273/6=45.5 g
1 ball=45.5 g
2 balls =2*45.5=91 g
3 balls =3*45.5=136.5 g
4 balls=4*45.5=182 g
5 balls =5*45.5=227.5 g

Answer:

Explanation:
Let's set up the ratio. We know that the actual length of the ship was 882 feet and we want to know how long the model will be. We also have a ratio of 1 model length to every 100 actual length. So we can write this as:
Model length
Ship length

100 actual length
And we can drop in some numbers (I'll also put in the variable

You are selling tickets for a high school basketball game. Student tickets cost $3 and general admission tickets cost $5. You sell 350 tickets and collect $1450. How many of each type of ticket did you sell?
Answers
Answer:
5 stars? Answer down below
Step-by-step explanation:
a+b=350 => a=350 - b
3a + 5b = 1450
3(350-b)+b=1450
1050-3b+5b=1450
2b=400
b=200
a=150
There are 200 student ticket and 150 general admission ticket sold.
What is selling price?The selling price is used to sell the item at a certain cost and can be calculated using the selling price formula. The amount that the buyer pays to buy the product is called the selling price.
Here,
We sold some number, x, of $5 tickets and some number, y, of $3 tickets. If we sold 350 tickets total then x + y = 350. If we made $1450 total on ticket sales, then the sum of y tickets at $3 plus x tickets at $5 needs to equal $1450.
So,
$3y + $5x = $1450
and x + y = 350
Solve system of equations.
3(350-x) + 5x = 1450
1050 -3x + 5x = 1450
2x = 400
x=200
y + 200 = 350
y=150
Thus, there are 200 student ticket and 150 general admission ticket sold.
