Answer:

He first made the mistake when multiplying 3(5-4x)

He accidentally put 15+12 x

It should be 15-12x

The answer would then come out to be x=2

-5= 2x+3(5-4x)

-5= 2x+15-12x

-5= -10x+15                     Can i get brainliest please?

-20= -10x

2= x

Answer:

k = 10

Step-by-step explanation:

The constant of proportionality of a graph in Mathematics is simply the ratio of y to x which can be called the slope.

It's given by; k = y/x

We are given; y = 30 and x = 3.

Thus;

k = 30/3

k = 10

Answer:

-12

Step-by-step explanation:

First, substitute the variables with the numbers.

(18-(-2*-5))+4(-5)

Using the order of operations, solve in the parentheses before anything else.

(18-(-2*-5))+4(-5)

(18-(10))+4(-5)

We can now multiply 4 by -5.

(18-(10))+4(-5)

(18-10)-20

It's probably easier if we subtract 10 from 18 before subtracting 20.

(18-10)-20

8-20

-12

Answer:

A(2)= 18, A(4)= 40, A(11)= 117

Answer:

Step-by-step explanation:

To find the length and width of the figure given the equation (s-2) (s+6) = 153​, we will find the equivalent value of s by factoring.

(s-2) (s+6) = 153​

s²+6s-2s-12 = 153

s²+4s-12-153 = 0

s²+4s-165 = 0

s²+15s-11s-165 = 0

s(s+15)-11(s+15) = 0

s+15(s-11) = 0

s+15 = 0 and s-11 = 0

s = -15 and 11

s cannot be negative

Hence s = 11

The length of the figure is s

The width is s+6

Length = 11

Width = 11+6 = 17

Hence the length of the figure is 11 and the width is 17

=======================================================

Explanation:

Let's go through the answer choices

Given:

Speed in still water = 12 miles per hour

Distance travel in upstream = 45 miles

Distance travel in downstream = 45 miles

Total time = 8 hours

To find:

The speed of current.

Solution:

Let the speed of current be x miles per hour.

Speed in upstream = (12-x) miles per hour

Speed in downstream = (12+x) miles per hour

We know that,

[tex]Time=\dfrac{Distance }{Speed}[/tex]

Time to cover 45 miles in upstream = [tex]\dfrac{45}{12-x}[/tex]

Time to cover 45 miles in downstream = [tex]\dfrac{45}{12+x}[/tex]

Total time is 8 hours. So,

[tex]\dfrac{45}{12-x}+\dfrac{45}{12+x}=8[/tex]

[tex]45\left (\dfrac{1}{12-x}+\dfrac{1}{12+x}\right)=8[/tex]

Taking LCM, we get

[tex]45\left (\dfrac{12+x+12-x}{12^2-x^2}\right)=8[/tex]

[tex]45\left (\dfrac{24}{144-x^2}\right)=8[/tex]

[tex]\dfrac{45\times 24}{8}=144-x^2[/tex]

On further simplification, we get

[tex]45\times 3=144-x^2[/tex]

[tex]135=144-x^2[/tex]

[tex]x^2=144-135[/tex]

[tex]x^2=9[/tex]

Taking square root on both sides.

[tex]x=\pm \sqrt{9}[/tex]

[tex]x=\pm 3[/tex]

Speed cannot be negative. So, x=3 only.

Therefore, the speed of the current is 3 miles per hour.

Answer:

$57.75

Step-by-step explanation:

96.25 x .40 = 38.5

96.25 - 38.5 = 57.75

The original price of the tire will be equal to $160.4.

The Percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that Gary had a 40% discount for new tires. The sale price of a tire was $96.25.

Let the original price of the tire be x. Now form the equation to have the price of the tire,

x ( 0.60 ) = $96.25

x = $96.25 / 0.60

x = $160.4

Therefore, the original price of the tire will be equal to $160.4.

Answer: explain how to graph an equation in slope-intercept form.

Step-by-step explanation: To graph a linear equation in slope-intercept form, we can use the information given by that form. For example, y=2x+3 tells us that the slope of the line is 2 and the y-intercept is at (0,3). This gives us one point the line goes through, and the direction we should continue from that point to draw the entire line.

the temperature of the mixture will be 60°

Answer:

  y +4 = 1/5(x +5)

Step-by-step explanation:

The equation of a line with slope m through point (h, k) in point-slope form is ...

  y -k = m(x -h)

You have m=1/5, (h, k) = (-5, -4). Putting these values into the formula gives ...

  y -(-4) = (1/5)(x -(-5))

  y +4 = 1/5(x +5)

Answer:

260 ways

Step-by-step explanation:

There are 3 scenarios.

Scenario #1, all colors used are different. A, B, C, and D each have their own individual color.

In this case, there would be 5x4x3x2=120 ways for this to happen.

(Since each color is different, after one is chosen there are only n-1 colors left, hence why it is 5x4x3x2)

Scenario #2, EITHER A&C OR B&D are the same color (Diagonal rectangles share no edges so they share a color).

In this case, there would be 2(5x4x1x3)=120 ways for this to happen. (Since we have two options, either A&C or B&D share a color, we multiply (5x4x1x3) by two to represent both options. Since the diagonal pairs must share one color, if, for example, A's color has been chosen from 5 options, C has only 1 option to choose from because it MUST match A's color)

Scenario #3, BOTH A&C AND B&D are the same color, meaning only 2 colors are used.

In this case, there would be 5x4x1x1=20 ways for this to happen.

(If A is already one color, B must choose a color from the remaining 4 options, C must match A so it has 1 option, similarily D must match B so it also has only 1 option, hence 5x4x1x1)

Now we add up all possible scenarios.

120+120+20=260 ways
