Answer:
The coffee is $3 or less
Step-by-step explanation:
Set up an inequality where c is the cost of one coffee:
17.50 [tex]\geq[/tex] 5c + 2.50
Solve for c:
17.50 [tex]\geq[/tex] 5c + 2.50
15 [tex]\geq[/tex] 5c
3 [tex]\geq[/tex] c
So, the coffee is $3 or less

Max was assigned to make 64 cookies for the bake sale. He made 125% of that number. 90% of the cookies he made were sold. How many of Max's cookies were left after the bake sale?
Answer: there are 8 cookies left
Step-by-step explanation:
Let's count how many cookies Max baked:
125% = 1.25
64 × 1.25 = 80
Let's count how many cookies were sold:
90% = 0.9
80 × 0.9 = 72
Leftover cookies:
80 - 72 = 8

A student is 7 years old. If you triple the teachers age and add the student's age the answer is 163. How old is the teacher?
Answer:
52
Step-by-step explanation:
We can write this out as an equation. Let's say that the teacher's age is x. Triple the teachers age plus the students age is 163, which can be written out as:
[tex]3x + 7 = 163[/tex]
We want to isolate the variable, so subtract 7 from both sides. This gives us:
[tex]3x = 156[/tex]
Finally, we divide both sides by 3, giving:
[tex]x=52[/tex]
So the teacher is 52 years old.
Hope this helps!
Answer: The teacher is 52.
Equation: 7+3t=163

Translate ƒ(x) = |x| so that it's translated up by 5 units and vertically stretched by a factor of 3. What's the new function g(x)? Question 20 options: A) g(x) = |3x| + 5 B) g(x) = |3x| +–5 C) g(x) = 3|x| +–5 D) g(x) = 3|x| + 5
Given:
The parent absolute function is
[tex]f(x)=|x|[/tex]
To find:
The new function if the parent function is translated up by 5 units and vertically stretched by a factor of 3.
Solution:
The translation is defined as
[tex]g(x)=kf(x+a)+b[/tex] .... (1)
Where, k is stretch factor, a is horizontal shift and b is vertical shift.
If 0<k<1, then the graph compressed vertically by factor k and if k>1, then the graph stretch vertically by factor k.
If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.
If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.
Parent function is translated up by 5 units. So, b=5
It is vertically stretched by a factor of 3. So, k=3.
There is no horizontal shift. So, a=0.
Now, putting k=3, a=0 and b=5 in (1), we get
[tex]g(x)=3f(x+0)+5[/tex]
[tex]g(x)=3f(x)+5[/tex]
[tex]g(x)=3|x|+5[/tex] [tex][\because f(x)=|x|][/tex]
Therefore, the correct option is D.

Quadrilateral ABCD is a parallelogram. Determine the measure of _A.
OA) 96°
B) 78°
C) 52°
OD) 39°
Answer:
The measure of angle A is: m∠A = 96
Therefore, option A is true.
Step-by-step explanation:
Given
m∠C = 3x
m∠D = x+52
We know that the opposite angles of a parallelogram are also equal.
Determining m∠A
It is clear that A is the opposite angle of C.
i.e.
m∠A = m∠C
as m∠C = 3x
so m∠A = 3x
Determining m∠B
It is also clear that B is the opposite angle of D.
i.e.
m∠B = m∠D
as m∠D = x+52
so m∠B = x+52
We know that the sum of the angles of a parallelogram is 360°.
so
m∠A + m∠B + m∠C + m∠D = 360°
3x + (x+52) + 3x + (x+52) = 360°
Group like terms
[tex]3x+x+3x+x+52+52=360^{\circ \:}[/tex]
[tex]8x+104=360^{\circ \:}[/tex]
Subtract 104 on both sides
[tex]8x+104-104=360^{\circ \:}-104[/tex]
Simplify
[tex]8x=360^{\circ \:}-104[/tex]
[tex]8x=256[/tex]
Divide both sides by 8
[tex]\frac{8x}{8}=\frac{256}{8}[/tex]
Simplify
[tex]x=32[/tex]
Thus,
The measure of the angle A is:
m∠A = 3x
substitute x = 32
m∠A = 3(32)
m∠A = 96
Hence, the measure of angle A is: m∠A = 96
Therefore, option A is true.

A store sells posters each poster cost the same amount door I sell the store reduces the price of each poster by $1.25 Kayla spent $17.17 on for posters at the sale price. What was the price of one poster before the sale?
Complete question :
store sells posters each poster cost the same amount door I sell the store reduces the price of each poster by $1.25 Kayla spent $17.17 on four posters at the sale price. What was the price of one poster before the sale
Answer:
5.5425
Step-by-step explanation:
Given that:
Price of posters are the same.
Let price of poster before sale = x
Sale on poster = reduction by $1.25
Price on sale = x - 1.25
Amount spent on 4 posters during sale = $17.17
Hence, cost per poster during sale :
$17.17 / 4
= $4.2925
Therefore, cost per poster before sale, x:
Price on sale = x - 1.25
$4.2925 = x - 1.25
x = $4.2925 + $1.25
x = $5.5425
The sale tax on $25,000 car is $1375 what is the sales tax rate
Answer:
Tax rate is 5.5% because 1,375/25,000 is equal to 0.055 which is 5.5 in percentage form. To prove it you can multiply 25,000 by 0.055 and get 1,375.
Step-by-step explanation:
Sales tax rate is 5.5% of cost of car.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given,
Price of the car = $25000
Tax on car = $1375
Sales tax rate = ($1375/$25000)×100
= 0.055 × 100
= 5.5%
5.5 % of sales tax is applied on the cost of car.

HELP ASAP PLEASE
Answer:
y=1/2x-3
Step-by-step explanation:
I hope you meant slope of the line...
You can find the slope like this-
1/2x= how you move (so m for move)
-3 =where you begin (so b for begin)
So next time you find the slope, just ask yourself where you "begin" (where the line starts) and how you "move" (how the line moves)
