Which is the solution for 3 (10x+4) = 8(3x + 6)

Answers

Answer:

x=6

Step-by-step explanation:

Answer:

3(10x+4)=8(3x+6)

Step 1: Simplify both sides of the equation.

3(10x+4)=8(3x+6)

(3)(10x)+(3)(4)=(8)(3x)+(8)(6)(Distribute)

30x+12=24x+48

Step 2: Subtract 24x from both sides.

30x+12−24x=24x+48−24x

6x+12=48

Step 3: Subtract 12 from both sides.

6x+12−12=48−12

6x=36

Step 4: Divide both sides by 6.

6x = 36

Answer:

x=6

The access code for a​ car's security system consists of digits. The first digit cannot be and the last digit must be . How many different codes are​ available?

Answers

Complete Question

The access code for a car's security system consists of 6 digits, the first digit cannot be 8 and the last digit must be odd, how many different codes are available

Answer:

There are 450000 possible different codes

Step-by-step explanation:

Given

Code = 6 digits

First = All but 8

Last = Odd

Required

Determine the possible number of codes

Analyzing each individual digit that makes up the code.

First: can be any of 0,1,2,3,4,5,6,7,9 ----- 9 possible numbers

Second, Third, Fourth and Fifth can be any of 0,1,2,3,4,5,6,7,8,9 since there's no restriction ----- 10 possible numbers

Last can be any of: 1,3,5,7,9 ----- 5 possible numbers

So, the number of possible selections is:

[tex]Selection = 9 * 10 * 10 * 10 * 10 *5[/tex]

[tex]Selection = 450000[/tex]

Hence, there are 450000 possible different codes

Line b passes through the point ( (6,4) and has a slope of -2. What is the equation of Line b in standard form?

2x + y = -11
x + 2y = -14
x + 2y = -16
2x + y = 16

Answers

Answer:

Equation of line b in standard form is: [tex]\mathbf{2x+y=-11}[/tex]

Option A is correct.

Step-by-step explanation:

We need to find equation of line b that passes through the point ( (6,4) and has a slope of -2.

First we need to find y-intercept of line using formula: [tex]y=mx+b[/tex] where m is slope and b is y-intercept.

Using m=-2 , x=6 and y=4 the y-intercept will be:

[tex]y=mx+b\\4=-2(6)+b\\4=12+b\\b=4-12\\b=-11[/tex]

Now finding the equation of line having slope m=-2 and y-intercept b=-11

[tex]y=mx+b\\y=-2x-11[/tex]

Writing the equation in standard form

[tex]y=-2x-11\\2x+y=-11[/tex]

So, equation of line b in standard form is: [tex]\mathbf{2x+y=-11}[/tex]

Option A is correct.

Answer:

Step-by-step explanation:

Answer:

Your first point should be at (0,-2), because of the y intercept. Then, since the slope is 3, you want to rise 3 and run 1. Go up 3, then to the right 1. That should be  your next point. Then do it again, and again, how many ever times you need to.

I made a PDF. Last time I tried doing this, the PDF did not work. Please tell me if the PDF is not working for you. My handwriting is also horrible XD. And sorry for my way of explaining, this is just how I was thought it, so it probably won't make sense.

So basically I'll try walking through what is going on in the picture.

So basically I just multiplied 2,412 by 24. I will incorporate the decimals later.

After multiplying, I got 57,888.

Now I will include the decimals.

You can see on the right side of the picture I counted how many decimal places 24.12 has. It has 2 decimal places.

Then I counted how many decimal places 2.4 has. It has 1 decimal place.

So I have to totally add the decimal places now.

2 decimal places plus 1 decimal place is 3 decimal places.

Three decimal places into 57,888 is 57.888.

2.4 × 24.12 is 57.888.

Each student get 3 erasers.

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

Total number of students = 6

Number of erasers = 20

Now,

Since, Total number of students = 6

And, Number of erasers = 20

Hence, Number of eraser getting by each students = 20 ÷ 6

                                                                   = 3.33

Thus, Each student get 3 erasers.

These are all correct. To divide fractions take the reciprocal (invert the fraction) of the divisor and multiply the dividend. This is the quickest technique for dividing fractions. The top and bottom are being multiplied by the same number and, since that number is the reciprocal of the bottom part, the bottom becomes one. Or just use a calculator lol.
