Answer:
1. (6,3)
2. x = 850, y = 150
Step-by-step explanation:
1. 3x-5y=3
4x-15y=-21
-9x +15y=-3 (multiply by -3)
4x-15y=-21
-5x=-30
x = 6
3(6)-5y=3
18-5y=3
-5y= -15
y= 3
so, x = 6, y = 3
2.
let x be regular
let y be reserved
x+y=1000
x= 5, y= 5+2=7 ("2 dollar more")
5x+7y=5300
x+y=1000
use the elimination method
x=850, y=150
so, the regular tickets were 850 and reserved tickets were 150 sold.

4. -7 = 3k - 3-7
this one to please lol
Answer:
7/3 =k
Step-by-step explanation:
4. -7 = 3k - 3-7
Combine like terms
-3 = 3k-10
Add 10 to each side
-3+10 = 3k-10+10
7 = 3k
Divide each side by 3
7/3 = 3k/3
7/3 =k
Answer:
7/3
Step-by-step explanation:
4 - 7 = 3k - 3-7
=> -3 = 3k - 10
=> -3 + 10 = 3k
=> 7 = 3k
=> 7/3 = k
=> k = 7/3
Solve the equation. x + (–6) = –9
Answer:

Answer:
x = -3
Step-by-step explanation:
Undo the addition of -6 by adding the opposite of that to both sides of the equation.
x + (-6) +(+6) = (-9) +(+6)
x -6 +6 = -9 +6
x = -3

Rates 13 feet in 5 steps
Answer:
[tex]2.6\frac{feet}{step}[/tex] or 2.6 ft/step
Step-by-step explanation:
In order to find the average number of feet traveled per step, divide the total number of feet traveled by the total number of steps taken:
[tex]\frac{13 feet}{5 steps}=\frac{13}{5}\frac{feet}{step}=2.6\frac{feet}{step}[/tex]
Therefore, for each step taken 2.6 feet are traveled (on average). We can say this as 2.6 feet per step or 2.6 ft/step.

which ordered pair represents the x-intercept for the linear equation, 3y+4×=8?
(0, 8/3)
(0, 2)
(2, 0)
(8/3, 0)
Answer: Third Choice. (2, 0)
Step-by-step explanation:
STEP ONE: Look over the given choice.
When the value of y is 0, the value of x would be the x-intercept.
The given choice are the following:
(0, 8/3)(0, 2)(2, 0)(8/3, 0)As we can see from the choices, the first two do not have the value of y as 0, therefore, they can be automatically neglected. Then, we are left with two choices left.
STEP TWO: Substitute the remaining values into the given equation
Given point = (2, 0)
3y + 4x = 8
3 (0) + 4 (2) = 8
0 + 8 = 8
8 = 8 [tex]\boxed {TRUE}[/tex]
Given point = (8/3, 0)
3y + 4x = 8
3 (0) + 4 (8/3) = 8
0 + 32 / 3 = 8
32/3 ≠ 8 [tex]\boxed {FALSE}[/tex]
Therefore, the ordered pair that represents the x-intercept is (2, 0).
Hope this helps!! :)

six quarts of paint is equally shared among 9 artists. how many quarts of paint does each artist get?
Answer:
2/3 quarts
Step-by-step explanation:
Paint used by 9 artists = 6 quarts
So, paint used by 1 artist if shared equally among the 9 artists
= 6 quarts/9
= 2/3 quarts
= 0.6666...... quarts
Rounding to the nearest hundredth, each artist would get approximately 0.67 quarts of paint.
To determine how many quarts of paint each artist gets when six quarts of paint are equally shared among nine artists, we can divide the total amount of paint by the number of artists. 6 quarts ÷ 9 artists = 0.6667 quarts per artist
To "equally share" means to divide or distribute something equally among a group of individuals or entities. It implies that each person or entity involved receives an equal portion or share of the item being distributed. This division ensures fairness and equal opportunities for everyone involved. The goal is to ensure that each recipient receives an equal amount or proportion of the item being shared.

can somebody help me with this, and if you could, can you show work?
Answer:
x=4
Step-by-step explanation:
Simplifying
-1(7 + -4x) = 9
(7 * -1 + -4x * -1) = 9
(-7 + 4x) = 9
Solving
-7 + 4x = 9
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '7' to each side of the equation.
-7 + 7 + 4x = 9 + 7
Combine like terms: -7 + 7 = 0
0 + 4x = 9 + 7
4x = 9 + 7
Combine like terms: 9 + 7 = 16
4x = 16
Divide each side by '4'.
x = 4
Answer:
x = 4
Step-by-step explanation:
-(7 - 4x) = 9 (Given)
-7 + 4x = 9 (Distributed)
-7 + 4x + 7 = 9 + 7 (Add 7 on both sides)
4x = 16 (Simplify)
4x/4 = 16/4 (Divide 4 on both sides)
x = 4 (Simplify)

Write the nth term of the following sequence in terms of the first term of the sequence. PLEASE HELP DUE IN 6 DAYS!!!!!!!

Answer:
a + 4(n-1)
Step-by-step explanation:
The first term is a+4, the second term is a+8, the third term is a+12, etc.
A common theme that we can notice is that we add 4 for each term. For example, the second term (t₂) equals t₁+4, the third term equals t₂+4 (as a+4+4 = a+8), and so on. Another way of writing this is that we multiply 4 by (term number - 1) and add that to a. We can write this as

Oscar and Maria each wrote an equation that they felt represented the proportional relationship between distance in kilometers and distance in miles. One entry in the table paired 152 km with 95 miles. If k represents the number of kilometers and m represents the number of miles, who wrote the correct equation that would relate kilometers to miles? Explain why.
Oscar wrote the equation k=1.6m, and he said that the unit rate 1.6/1 represents kilometers per mile.
Maria wrote the equation k=0.625m as her equation, and she said that 0.625 represents kilometers per mile.
9514 1404 393
Answer:
Oscar
Step-by-step explanation:
On the face of it, you can see that the number of kilometers representing a given distance is greater than the number of miles. (152 > 95)
This means the constant of proportionality (a) in the equation ...
k = am
must be greater than 1. You can find its value by solving this equation for 'a' and using the table entries for k and m:
a = k/m = 152/95 = 8/5 = 1.6
The correct relation is ...
k = 1.6m . . . . . Oscar wrote the correct equation
