Does the following equation have one solution, infinite solutions, or no solutions? 6x -4 = 5x +8

Answers

[tex]6x-4=5x+8[/tex]

Solve the equation. For the easier way, move the x-term to the same term and constant to the same side.

[tex]6x-5x=8+4\\x=12[/tex]

Because we can solve the value of x. Therefore, the following equation has one solution.

Here's the thing that you should know for the solutions of equations.

When the equation is true (When both sides are the same Ex. 1 = 1, the solution will be infinite.)

When the equation is false (When both sides have different value. Ex. 0 = 3 then there won't be any solutions.)

When the equation can be solved normally for the variable, the solution will be one.

Answers

Answer:

Step-by-step explanation:

Perry and Alberto are selling fruit for a school fundraiser. Customers can buy small boxes of
tangerines and large boxes of tangerines. Perry sold 7 small boxes of tangerines and 12 large
boxes of tangerines for a total of $283. Alberto sold 8 small boxes of tangerines and 6 large
boxes of tangerines for a total of $200. Find the cost each of one small box of tangerines and one
large box of tangerines.

Answers

Answer: Small box: $13; Large box: $16

Explanation:

Make two individual equations for Perry and Alberto. Perry's equation would be 7x+12y=283. Alberto's equation would be 8x+6y=200. The best way to find the variables is to change the equations into slope-intercept form. Perry's equation would change to y=-7/12x+283/12 and Albert's equation would change to y=-4/3x+100/3. You can try substituting and plugging -4/3x+100/3 into the other equation, so they equal each other. But, you can also just graph the equation into a graphing calculator or Desmos. When graphing it, the point of intersection should be (13,16), so the cost of a small box tangerines is $13 and a large box of tangerines is $16.

5h + 10 = 4h + h + 15

Answers

Answer:

h = no solution

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define

5h + 10 = 5h + 15

Step 2: Solve for h

Subtract 5h on both sides: 10 ≠ 15

Here we see that 10 does not equal 15.

∴ h has no solution.

Final Answer: No Solution

Steps/Reasons:

Step 1: Simplify [tex]4h + h + 15[/tex] to [tex]5h + 15[/tex].

[tex]5h + 10 = 5h + 15[/tex]

Step 2: Cancel [tex]5h[/tex] from both sides.

[tex]10 = 15[/tex]

Step 3: Because [tex]10 = 15[/tex] is false, there is no solution.

Grapes cost $1.87 per pound. How much would it cost for 4.25 pounds of grapes?

Answers

Answer:

7.95$

Step-by-step explanation:

1.87 $ per 1 lb

1.87 * 4.25 = 7.95$

Answer:

$7.95 for 4.25 lbs. of grapes

Step-by-step explanation:

so your going to multiply $1.87 by 4.25 to get the total amount of money needing to be paid in or der to buy the 4.25 lbs. of grapes:

$1.87 * 4.25 = 7.9475

now turning it into money by rounding to the hundredths place:

7.9475 = $7.95

So you would have to pay $7.95 for 4.25 lbs. of grapes but logically you would bring 8 dollars to buy it, but down to the cents it would be $7.95.

What is Meant by Solution of a Linear Equation?

The solution of a linear equation is defined as the points, in which the lines represent the intersection of two linear equations. In other words, the solution set of the system of linear equations is the set of all possible values to the variables that satisfies the given linear equation.

According to the questions,

On Saturday morning, Owen earned $24 raking leaves.

By the end of the afternoon he had earned a total of $62.

The equation to determine whether Owen earned $38 or $31 on Saturday afternoon.

⇒ $62 - $24 = $38

⇒ $24 + $ x = 62

Hence the required equation is $24 + $ x = 62.

HELP PLZ!!!!! A fireman's ladder is placed against a wall. The bottom of the ladder is 15 ft away from the wall and the top of the ladder touches the wall at a point 80 ft above the ground. Assuming that the slope is positive, what is the slope of the ladder? Round your answer to the nearest hundredth.

Answers

Answer:

5.3

Step-by-step explanation:

We know that the bottom of the ladder is 15 feet from the wall, and it touches the wall 80 feet above the ground. Imagine it like two points on a graph. One is at the origin (0,0). That represents the bottom of the ladder. The next one is at (80,15), which represents where the top is. To find slope, we divide rise (y-values) over the run (x-values). The y value increases by 80, while the x increases by 15. 80 divided by 15 equals about 5.3

To find:

The values of a, b and c.

Solution:

We have,

[tex]y=\dfrac{2}{3}x^2+3[/tex]

It can be written as

[tex]y=\dfrac{2}{3}x^2+(0)b+3[/tex]

On comparing this equation with [tex]y=ax^2+bx+c[/tex], we get

[tex]a=\dfrac{2}{3},b=0,c=3[/tex]
