Answer:
4x + 8 = 7.2 + 5x
1. 4x - 4x + 8 = 7.2 + 5x - 4x
2. 8 = 7.2 + x
3. 8 - 7.2 = 7.2 - 7.2 + x
4. 0.8 = x
Step-by-step explanation:
Final Answer: [tex]x = 0.8[/tex]
Steps/Reasons/Explanation:
Question: Equation with variables on both sides: decimals & fractions [tex]4x + 8 = 7.2 + 5x[/tex].
Step 1: Subtract [tex]4x[/tex] from both sides.
[tex]8 = 7.2 + 5x - 4x[/tex]
Step 2: Simplify [tex]7.2 + 5x - 4x[/tex] to [tex]7.2 + x[/tex].
[tex]8 = 7.2 + x[/tex]
Step 3: Subtract [tex]7.2[/tex] from both sides.
[tex]8 - 7.2 = x[/tex]
Step 4: Simplify [tex]8 - 7.2[/tex] to [tex]0.8[/tex].
[tex]0.8 = x[/tex]
Step 5: Switch sides.
[tex]x = 0.8[/tex]

Answer:
b There is No Solution for this system
Step-by-step explanation:
When graphing out equations, the two equations have to intersect at one point to have a solution. If they are parallel, it means that they will never intersect at one point and thus there is no solution for the system. A pair of lines would only have infinitely many solutions when both lines are at the same position travelling in the same direction, overlapping each other.

Find the two square roots of 144.
Answer:
The square root function
sqrt(144) or √144 produces a single positive value, 12.
However if you have an equation
x² = 144, then you have two possible values for x, 12 and -12.
Two ways to look at it.
x² - 144 = 0
Difference of two squares
(x+12)(x-12) = 0
x = -12, 12
x² = 144
x = ±√144
x = ±12
x = -12, 12
Answer:
12 and -12
Step-by-step explanation:
144 is a perfect square which means that a number multiplies to it with the same number. In this instance both 12 and -12 equal 144.
12 x 12 = 144
-12 x -12 = 144 (two negatives equal a positive)

Answer:
K = -2
Step-by-step explanation:
K represents the y-intercept, which is where the line crosses the y axis. We can see from the y = -4x -2, that -2 is the y-intercept, because in y = mx + b, b is the y -intercept.

Final Answer: All Real Numbers
Steps/Reasons/Explanation:
Question: Solve for a. [tex]4(a + 3)=12 + 4a[/tex].
Step 1: Expand.
[tex]4a + 12 = 12 + 4a[/tex]
Step 2: Cancel [tex]4a[/tex] on both sides.
[tex]12 = 12[/tex]
Step 3: Since both sides equal, we would have infinitely many solutions.

A 24 oz. bottle of pop costs $2.25. What is the price per ounce? How did you get that answer?
Answer:10.07
Step-by-step explanation: I got my answer by dividing 24 and 2.25. First, I set up my equation, 24 / 2.25. Then, i multiply 2.25 by 10, which was 22.5. Then i subtracted, which was 1.5 then i bring down my 0. 2.25 doesnt go into 1.50 so I add a 0. then i bring down a 0.

We are holding a 1k walk to raise money for walk across America. This organization provides shoes to people in need. It will be held at Millennium Park. It will cost us $250 to rent the park for the day. Each person will get a t-shirt and snacks, which cost us $10 per person. We plan to Charge $20 per person to participate. Assume y is the cost, and x is the number of people. Which two equations represent this situation? y = 10x + 250 y = 10x – 250 y = 20x y = 20x Option 2 Option 4 y = 20x + 250 y = 10x + 20 y = 10x V = 250x
Answer:
The equations y=10x+250 and y=20x represent the situation.
Step-by-step explanation:
Given that:
Cost to rent the park = $250
Cost per person for t-shirt and snack = $10
Cost of participation = $20
y = cost
x = number of people
Cost for the organization;
y = 10x + 250
Amount generated from people's participation
y = 20x
Hence,
The equations y=10x+250 and y=20x represent the situation.
