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

6(x + 3) − 3 = 39 whats the solution of x?
Answer:
x = 4
Step-by-step explanation:
6(x+3)-3= 39
6x+18-3 =39
6x+15 =39
-15 -15
6x= 24
/6 /6
x=4
Answer:
x=4
Step-by-step explanation:
Do distributive property
6(x + 3) − 3 = 39(multiply 6 by all the numbers in the brackets)
6x+18=39 (subtract 18 on both sides)
6x=24 (divide 6 on both sides)

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.

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.
