The first one (Cedric is correct because he used the inverse of subtraction and added 4.5)
Step-by-step explanation:
First....I'll do it my way
z - 4.5 = -1.5
Add 4.5 on both sides
z - 4.5 + 4.5 = -1.5 + 4.5
z = 3
This should be our answer.....and so who did it right?
Cedric did
Which is the true statement?
Cedric is correct because he used the inverse of subtraction and added 4.5

Give three examples of equations where there would be no solution
Answer:
1) 2x+1 = 2x-4
2) 6x+2=3(2x+1)
3) -4x -5=-2(2x)+2
Step-by-step explanation:
We need to give three examples of equations where there would be no solution.
First we will define equation with no solution.
If solving an equation you get the result as 3=5 but 3 is not equal to 5, so the equation has no solution.
Examples of equations where there would be no solution
1) 2x+1 = 2x-4
2x-2x=-4-1
0=-1 ( false)
So, the equation has no solution.
2) 6x+2=3(2x+1)
6x+2=6x+1
6x-6x=1-2
0=-2 (false)
So, the equation has no solution.
3) -4x -5=-2(2x)+2
-4x-5=-4x+2
-4x+4x=2+5
0=7 (false)
So, the equation has no solution.
A man spend 10% of his salary on rent, 25% on food, 18% on transportation and the balance he saves. If his salary is $1500 per month, how much does he save each month?

Which represents a function?
Answer:
[tex] \boxed{ \text{Option \: D}}[/tex]
Step-by-step explanation:
All the relations are not functions. We can determine ( identify ) whether a relation is function or not by drawing a vertical line intersecting the graph of the relation. This is called vertical line test.
If the vertical line intersects the graph of a relation at one point , the relation is a function .If it cuts at more than one point , it is not a function. It means that if there are more points of the graph of a relation of a vertical line , same first component ( pre - image ) has more images ( second component ) which is not the function by definition.--------------------------------------------------
Let's check all of the options :
☐ Option A :
The vertical line cuts the graph at two points. So , the graph does not represent a function.☐ Option B
No! This is also not a function as the vertical line cuts the graph at two points.☐ Option C
Nah! This too can't be called a function as the vertical line cuts the graph at two points.☑ Option D
Yep! The vertical line cuts the graph at one point. Thus , the graph represents a function.Yayy!! We found our answer. It's ' Option D '.
Hope I helped ! ツ

Consider a cookie recipe in which 1 1/2 cups of chocolate chips to make cookies. Lara wants to double the number of 25 cookies. How many cups of chocolate chips should she use?
Answer:
3 cups
Step-by-step explanation:
Double 1.5 to get 3.
Lara would need 3 cups of chocolate chips
The cookie recipe uses of [tex]1\frac{1}{2}[/tex] cups of chocolate chips to make 25 cookies. The ratio of chocolate chips to cookies is [tex]1\frac{1}{2}[/tex] : 25
If Lara wants to double the number of cookies she wants to make, it means she wants to make 50 cookies (25 x 2). In order to determine the cups of chocolate chips that she would need, we also need to double the cups of chocolate chips
Chocolate chips needed = [tex]1\frac{1}{2}[/tex] x 2
Convert the mixed fraction to an improper fraction
3/2 x 2
= 3 cups

Step-by-step explanation:
Given
[tex]5x-3y=14[/tex] -- (1)
[tex]3x-5y=2[/tex] -- (2)

Find x and y
We'll solve this using elimination method.
