1) A craftsman makes 40 items in 8 hours. How many
hours will he take to make 75 items?
Answer:
15 hours
Step-by-step explanation:
40/8 = 75/x
40x = 600
x = 15
Answer:
About 15
Step-by-step explanation:
40 items/8 hours = 5 items per hour( his rate)
75 items/ 5 items per hour= 15 hours
At his rate it will take him about 15 hours to make 75 items
4. You buy a video game and pay for it with a $50 bil. Write an expression that can be used to find out how much change you shoud receive.
Answer:
[tex]\boxed{\textsf {\textbf{The amount returned by the shopkeeper is \$ 50 - x .}}}[/tex]
Step-by-step explanation:
Given that I buy a video game and pay $ 50 to the shopkeeper . And we need to find the expression how much change should I receive .
So , let us take that the video game costs x . There can be two cases .
★ Case 1 :-
When the cost of the product is same as the amount given . When the cost of the video game is $50 then the shopkeeper will give us no change .
[tex]\boxed{\red{\sf Returned\ change = \$ 0 }}[/tex]
[tex]\rule{200}2[/tex]
★ Case 2 :-
When the cost of the video game is less than $50 then the shopkeeper will return us some change that is equal to the difference if the amount given to shopkeeper and the cost of the video game .
If the cost of the video game is x , then the amount given to us by the the shopkeeper will be ,
[tex]\boxed{\red{\sf Returned\ change = \$ 50 - x }}[/tex]

3 – 5x < -4x + 9
Answer:
x>-6
graphing (-6,0)
Step-by-step explanation:
3-5x<-4x+9-- Add 5x to -4x
3<x+9--- subtract 9 from both sides
-6<x
387.4 rounded to the nearest tenth
Answer:
387.4 is the answer

Answer:
[tex]y=\frac{2}{3} x-1[/tex]
Step-by-step explanation:
Linear equations are typically organized in slope-intercept form:
[tex]y=mx+b[/tex] where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept (the value of y when the line intercepts the y-axis)
1) Find the slope of the line (m)
The equation for slope: [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] when the given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug in the given points (3,1) and (6,3)
[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]=\frac{3-1}{6-3}\\=\frac{2}{3}[/tex]
Now, plugging this back into [tex]y=mx+b[/tex], our equation looks like this:
[tex]y=\frac{2}{3} x+b[/tex]
2) Find the y-intercept of the line
To find the y-intercept, we take the equation that we have so far and plug in any given point to solve for b. For example, we can use the point (3,1):
[tex]1=\frac{2}{3}*3+b\\1=2+b[/tex]
Subtract both sides by 2 to isolate b
[tex]1-2=2+b-2\\-1=b[/tex]
3) Plug m and b into y=mx+b
[tex]y=\frac{2}{3} x-1[/tex]
I hope this helps!
Which pairs of equations are parallel?
a) y = 3x + 4 and y = 3x+1

Step-by-step explanation:
Find x in triangle ABC using geometric means.
Given:
The figure of a right angle triangle.
To find:
The value of x using geometric mean.
Solution:
According to the geometric mean altitude theorem, if an altitude h divides the hypotenuse in two parts a and b, then
[tex]\dfrac{a}{h}=\dfrac{h}{b}[/tex]
Let attitude from A touches the hypotenuse at point D.
Using this in the given triangle, we get
[tex]\dfrac{BD}{AD}=\dfrac{AD}{CD}[/tex]
[tex]\dfrac{12}{x}=\dfrac{x}{3}[/tex]
[tex]12\times 3=x^2[/tex]
[tex]36=x^2[/tex]
Taking square root on both sides, we get
[tex]\pm \sqrt{36}=x[/tex]
[tex]\pm 6=x[/tex]
Side cannot be negative. Therefore, the only value of x is 6.

Answer:
(2, -12)
Step-by-step explanation:
Answer:
(2, -12)
Step-by-step explanation:
(x, y ) = (0, -8)
2 units right = +2 units to the x-coordinate
4 units down = -4 from the y-coordinate
(0+2, -8-4)
= (2, -12)

"-5 increased by one-half of a number is a
maximum of 3."
We can write the given statement as expression -
- 5 + (1/2)x = 3
What is expression?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is the statement -
"-5 increased by one-half of a number is a maximum of 3"
We can write it as an expression -
- 5 + (1/2)x = 3
Therefore, we can write the given statement as expression -
- 5 + (1/2)x = 3

Help pls (pls dont write absolute nonsense on here pls i really need help)
The sum of two numbers is 30 and their difference is 4. Find the numbers
Answer:
17 and 13
Step-by-step explanation:
So you can set up an equation:
let x be the greater number
this means that the smaller number would be 4 less than x, because their difference is 4, so x - 4.
The sum is 30, so x + (x - 4) = 30
Then, solve:
x + (x - 4) = 30
x + x - 4 = 30
combine like terms
2x - 4 = 30
add 4 to both sides
2x = 34
divide both sides by 2
x= 17
Now you know the greater number is 17. Since they have a difference of 4, you can do 17 - 4 = 13 to get the smaller number.
The numbers are 17 and 13

Answer:
56 square feet
Step-by-step explanation:
If you take the problem and divide into two rectangles by drawing the line up from the bottom 4.
You end up with one rectangle that is
8x4
and a second thats
4x6.
The area is then calculated by taking the length and multiplying by the width of the first (8 x 4) and adding to the same process of the second (4x6)
Thus
32 + 24 = 56 square feet
Answer:
32 + 24 = 56 square feet
