Answer:

Step-by-step explanation:

Pick the variable you want to eliminate. Determine the coefficients of that variable in the two equations. Negate one of them. Multiply each equation by the coefficient that came from the other equation.

__

To eliminate x

The x-coefficients are 4 and 3. If we negate 4, then the resulting y-coefficient will be positive. We choose to multiply the first equation by 3, the second by -4.

Here is the result of adding those:

  3(4x +5y) -4(3x -2y) = 3(7) -4(-12)   ⇒   23y = 69

To eliminate y

The y-coefficients are 5 and -2. If we negate -2, then the resulting x-coefficient will be positive. We choose to multiply the first equation by 2 and the second by 5.

Here is the result of adding those:

  2(4x +5y) +5(3x -2y) = 2(7) +5(-12)   ⇒   23x = -46

Answer:

Step-by-step explanation:

to kill x: duplicate the primary by 3, and the moment by -4 to eliminate y: increase the primary by 2, and the moment by 5 Step-by-step explanation: Pick the variable you need to eliminate. Decide the coefficients of that variable within the two conditions. Refute one of them. Increase each condition by the coefficient that came from the other equation. __ To dispense with x The x-coefficients are 4 and 3. On the off chance that we invalidate 4, then the coming about y-coefficient will be positive. We select to increase the primary condition by 3, the moment by -4. Here is the result of including those: 3(4x +5y) -4(3x -2y) = 3(7) -4(-12) ⇒ 23y = 69 To dispose of y The y-coefficients are 5 and -2. If we nullify -2, at that point the coming about x-coefficient will be positive. We select to duplicate the primary condition by 2 and the moment by 5. Here is the result of including those: 2(4x +5y) +5(3x -2y) = 2(7) +5(-12) ⇒ 23x = -46

Answer:

a = 1

Step-by-step explanation:

Original Equation:

-1 + 8 = 10 - 3a

Add 1 to both sides

8 = 11 - 3a

Subtract 11 from both sides

-3 = -3a

Divide both sides by -3

a = 1

Answer:

62-24=38

or 24 + x = 62

Step-by-step explanation:

The equation to determine whether Owen earned $38 or $31 on Saturday afternoon ⇒ $24 + $ x = 62.

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.

The theater charges ten dollars for admission and four dollars for each drink

Answer

wrong topic, this is about economics

Answer:

If I am not mistaken the answer is x<-27/2.

Given:

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

This equation is in the form [tex]y=ax^2+bx+c[/tex].

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]

Therefore, the correct option is b.

Step-by-step explanation:

Step 1: Define

5h + 10 = 5h + 15

Step 2: Solve for h

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.

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

Answer:

200%.

100% of 12 is 12 since for example if a coat is 10$ and 100% off then its now 0$. Therefore 200% is twice of 12 making it 24.

24=200% of 12

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.

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.

[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.
