HELP: Cho charges $1500 to build a small deck and $2500 to build a large deck. During the spring and summer, she built 5 more small decks than large decks.
If she earned $23,500 how many of each type of deck did she build?
Answer:
if she build x numbers of large decks, therefore small decks would be (x + 5)
1500*(x+5)+2500x =23500
1500x+7500+2500x=23500
4000x+7500 =23500
4000x=23500-7500
4000x=16000
x=4
4+5=9
cho built 4 large decks and 9 small decks

Given f(x) = 5^2x,evaluate f (-1), f (0),and f (2)
The values of f(-1), f(0), and f (2) are 0.04, 1 and 625, respectively
How to evaluate the function?The function is given as:
f(x) = 5^2x
For f(-1), we have x = -1
This gives
f(-1) = 5^(2 * -1)
f(-1) = 0.04
For f(0), we have x = 0
This gives
f(0) = 5^(2 * 0)
f(0) = 1
For f(2), we have x = 2
This gives
f(2) = 5^(2 * 2)
f(2) = 625
Hence, the values of f(-1), f(0), and f (2) are 0.04, 1 and 625, respectively

An expression is shown.
(0.25n - 0.3) – (0.8n - 0.25)
Create an equivalent expression without parentheses.
Answer:
-0.55n - 0.05
Step-by-step explanation:
You can start by distributing:
(0.25n - 0.3) - (0.8n - 0.25)
0.25n - 0.3 - 0.8n + 0.25
Then, you can combine like terms(0.25n & -0.8n; -0.3 & 0.25)
-0.55n - 0.05
Answer:
-0.55n - 0.05
Step-by-step explanation:
(0.25n - 0.3) – (0.8n - 0.25)
When subtracting the signs change
0.25n - 0.3 - 0.8n + 0.25
Regroup like terms
0.25n - 0.8n - 0.3 + .25
Combine like terms

Which number completes the table for y = x^2?
a.) -9
b.) 9
c.) 6
d.) -6
Answer:
B
Step-by-step explanation:
We can substitute the x value given, -3, into our equation, y = x^2, to get what the y would be:
y = x^2
y = (-3)^2
When a negative number is squared, it is positive, so (-3)^2 = 9, and:
y = 9
This is option b
Answer:
B) 9
Step-by-step explanation:
We are given the equation y = x^2 for the table, and a x value.
To find the y value that corresponds to that x value, we must plug the x value in the equation.
Y =x^2
Y= -3^2
Y=9

work out the volume of the block of wood
Step-by-step explanation:
Given :-
A block of wood has a mass of 3.5 kilogram. The wood has density 0.065 kg/m³.And we need to find out the volume of the wood. Density , volume and mass are related as ,
Density :-
Mass per unit Volume .[tex]\implies\rm Density =\dfrac{Mass}{Volume}[/tex]
Substitute the respective values :-
[tex]\implies\rm Density =\dfrac{Mass}{Volume}\\\\\rm\implies 0.065 kg/m^3=\dfrac{3.5kg}{V}\\\\\rm\implies Volume = \dfrac{3.5kg}{0.065 kg/m^3}\\\\\implies\boxed{\red{\rm Volume = 53.84 m^3}}[/tex]
Hence the volume is 53.84 m³ .

Amy has three times as many Star Wars toys as Carly. Total they have 160 Star Wars toys. How many Star Wars toys does Amy have?
Answer:
53
Step-by-step explanation:
Amy has 120 star war toys.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Amy:
Number of toys = 3x
Carly:
Number of toys = x
Now,
In total, they have 160 Star Wars toys.
So,
x + 3x = 160
4x = 160
x = 40
Now,
3x = 3 x 40 = 120
x = 40.
Thus,
Amy has 120 toys.
Carly has 40 toys.
