Wait... this doesn’t make sense because it doesn’t tell you if there was tax, how many friends there were, or tips.
Answer:
16/y = x
Step-by-step explanation:
You cannot solve for the question yet. However, you can create an equation!
we know that each person paid 16 dollars.
We don’t know how much the bill was or how many people were there.
So out equation looks like;
z/y = x
or
z * x = y
z = how much each person paid.
y = how much each person paid.
x = how many people paid.
Substitute with what we know.
16/y = x
16 * x = y
Now you will be able to substitute for either x or y to find either answer.

last season, your favorite basketball team won 20 games. So far this season, your favorite basketball team has won 31 games. What is the percent change in the number of games that your favorite team won from last season to this season?
Answer:
There is a 55% increase in the number of games.
Step-by-step explanation:
Step 1: Calculate the change (subtract old value from the new value)
Step 2: Divide that change by the old value (you will get a decimal number)
Step 3: Convert that to a percentage (by multiplying by 100 and adding a % sign)
Answer:
20=100%
31=x
31*100/20=155%

A video rental store charges a $20 membership fee and $2.50 for each video rented. Find the slope and y-intercept for the data. (hint: create a table or graph comparting the total cost per video rented).
slope:
y-intercept:
Answer:
y=2.50x+20
Step-by-step explanation
Slope intercept equation is = y=mx+b
So you BEGIN with 20, which is your membership fee (it only gets charged once) then your mx is your slope. 2.50 is your slope because they earn 2.50 for each (x) video rented.
you place a number beside the x for each video rented. For example, if you rent 2 videos then you write this y=2.50(2)+20
Answer:
slope:2.50
y intercept:20$
Step-by-step explanation:
Consider the equation Ax+By=−36. If the x-intercept is (−3,0) and the y-intercept is (0,9), what are the values of A and B?
Answer:
A= 12
B = -4
Step-by-step explanation:
( -3,0) & (0,9) should satisfy the equation Ax + By = -36
when ( -3,0)
-3A+ 0 = -36
A = 12
when (0,9)
0 + 9B = -36
B = -4
The value of A and B is 12 and -4.
Given that,
The equation is Ax + By = -36.And, the x-intercept is (-3,0) and the y-intercept is (0,9).Based on the above information, the calculation is as follows:
Ax + By = -36
When (-3,0)
So,
-3A+ 0 = -36
A = 12
Now
when (0,9)
So,
0 + 9B = -36
B = -4
Therefore we can conclude that the value of A and B is 12 and -4.

Which of these is a Pythagorean triad?
A. 5, 12, 13
B. 1, 2, 3
C. 6, 9, 10
Answer:
A) 5, 12, 13
Step-by-step explanation:
[tex]5^2 + 12^2 = 169[/tex]
[tex]13^2 = 169[/tex]
∴ Option A is a Pythagorean triad.
[tex]1^2 + 2^2 = 5[/tex]
[tex]3^2 = 9[/tex]
∵[tex]5\neq 9[/tex], ∴ Option B is not a Pythagorean triad.
[tex]6^2 + 9^2 = 117[/tex]
[tex]10^2 = 100[/tex]
∵[tex]117\neq 100[/tex], ∴Option C is not a Pythagorean triad.
∴ A is the only Pythagorean triad out all three options.

Every week, a car dealer ship sells at least 5 minivans. Write an inequality that represents this situation. Let c represent the number of minivans sold each week.
Answer:
we conclude that an inequality 'c ≥ 5' denotes this situation.
Step-by-step explanation:
Given
A car dealer ship sells at least 5 minivansWhen we talk about 'at least', it means we are talking about '≥' in terms of representing the 'at least' in inequality symbol.
For instance,
'm≥n' means 'm' is greater than or equal to 'n'.
It means 'm' is at least equal to 'n'.
Coming back to the question,
Let 'c' represent the number of minivans sold each week.As the car dealer ship sells at least 5 minivans. so the
inequality will be: c ≥ 5
Thus, we conclude that an inequality 'c ≥ 5' denotes this situation.

Amara needs 45kilograms of meat to feed her 2pet dragons each day. Each pet dragon eats the same amount of meat.
How many kilograms of meat does Amara need to feed 4 pet dragons each day?
[tex]\huge\underline{\overline{\mid{\bold{\red{ANSWER}}\mid}}}[/tex]
She needs 45 kg meat for 2 pets
each pet feed the same, i.e,
one pet eats = 45/2 = 22.5 kg meat
then 4 pet dragons will eat = [tex] 22.5kg \times 4 = 90 kg [/tex] meat.
Hence, Amara needs 90 kilograms of meat to feed 4 pet dragons each day.

Option C is the best choice.
Step-by-step explanation:
✺ First , Let's know about Corresponding angles :
A pair of interior and exterior angles which lies to the same side of a transversal.Remember that the corresponding angles are always equal.The easiest way to think of corresponding angles is the 'F - Pattern'.✎ Now, In our case , x ° and ( 3x - 70 ) ° are corresponding angles. Set up an equation and solve for x.
[tex] \sf{x = 3x - 70\: ( \: being \: corresponding \: angles})[/tex]
[tex] \longrightarrow{ \sf{x - 3x = - 70}}[/tex] { Move 3x to left hand side and change it's sign )
[tex] \longrightarrow{ \sf{ - 2x = - 70}}[/tex] { Combine like terms }
[tex] \longrightarrow{ \sf{ \frac{ - 2x}{ - 2} = \frac{ - 70}{ - 2} }}[/tex] { Divide both sides by -2 }
[tex] \longrightarrow{ \sf{x = 35}}[/tex]
The value of x is 35°
Now, As we are asked to find the value of m [tex] \angle[/tex] ABC , replace the value of x :
[tex] \sf{m \angle \: ABC \: = (3x - 70) \degree}[/tex]
[tex] \dashrightarrow{ \sf{(3 \times 35 - 70) \degree}}[/tex]
[tex] \dashrightarrow{ \sf{(105 - 70) \degree}} [/tex]
[tex] \longrightarrow{ \boxed{ \sf{35 \degree}}}[/tex]
Therefore , m [tex] \angle[/tex] ABC = 35°
And we're done !
Hope I helped!

What is the y-intercept of function f?
Answer: it’s not 5 I got that wrong
Step-by-step explanation:
y-intercept of function f is 1.
What is a function?Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given function
f(x) = -3x -2 , -∞ < x < -2
= -x + 1, -2 ≤ x < 3
= 2x + 5, 3 ≤ x < ∞
For y-intercept, x =0, f(x) = -x + 1 [∵ -2 < 0 < 3]
f(0) = -0 + 1
= 1
Hence, y-intercept of function f is 1.
