We need to find how much farther in miles does Isabel live from school than Janet.

How to subtract, unlike fractions?

Addition and subtraction of unlike fractions:

Step I: Obtain the fractions and their denominators.

Step II: Find the LCM (least common multiple) of the denominators.

Step III: Convert each fraction into an equivalent fraction having its denominatorequal to the LCM (least common multiple) obtained in Step II.

Now, 3/4-2/3=9/12-8/12

=1/12

Therefore, Isabel lives 1/12 mile farther than Janet from the school.

Hey There!

Steps to solve (steps will be in numerical order)

1. Find the lcd of the fractions $(3)/(4)$ and $(2)/(3)$ . The lcd for both problems will be 12.

2. To rewrite $(3)/(4)$ you have to multiply the numerator and denominator by three since the lcd is 12. So you're new fraction will be $(9)/(12)$ . For the second fraction, since the lcd is 12 you will multiply the numerator and denominator by 4. You're new fraction will be $(8)/(12)$ .

3. Since the problem contains the math keyword "Further", you automatically know you have to subtract, now subtract $(9)/(12)$ - $(8)/(12)$ . First, start of by subtracting the numerators, so subtract 9-8=1 , remember the denominators will always stay the same.

In conclusion, you're answer will be $(1)/(12)$ , so Isabel lives $(1)/(12)$ farther away from Janet.

How do you solve equations that contain addition or subtraction?

Answers

Any equation given, with a variable, could be solved by applying the inverse operation.

Example:-

4 + x = 8
-4 -4

x = 8 -4
x = 4

Answer; x = 4

To learn the basics I would suggest using this simple model to solve. Remember, that you can add, subtract, multiply, or divide anything to both side of the equal sign.
Ex. 5 + 5 = x
-5 -5

Now, let's try a real problem:

10 + x = 15
Now, I know this may seem to be an easy problem, but by using the method I am about to show you, you will be able to solve any addition, subtraction, even multiplication, and division equation!
This would be how you solve:
10 + x = 15
-10 -10
----------------------------------------
x = 5

Hope this helped!

SOLVE BY SUBSTITUTION:3x-2y=14

PLEASE HELP WORTH 10 POINTS! AKA SHOW WORK:)

Answers

1)
3x-2y=14
y=5x

So we plug in y=5x into 3x-2y=14

We get:

3x-2(5x)=14
3x -10x=14
-7x=14
x=-2

So we found x, now we need to find y. We can simply plug in x into the equation and get y.

y=5x
y=5(-2)
y=-10

So your answer will be (-2,-10).

2)
x-2y= -2
y= 2x+4

Once again plug in y=2x+4 into x-2y=-2

x-2(2x+4) = -2
x-4x-8=-2
-3x-8=-2
-3x = 6
x= -2

Now we plug back in x and solve for y :)

y=2x+4
y=2(-2)+4
y=-4+4
y=0

So our solution would be (-2,0).

3)
x+2y=-7
x-5y=7

Multiply the second equation by -1

-x+5y=-7

Now add that equation with the other one:

x+2y=-7
+
-x+5y=-7
-----------------
7y=-14
y=-2

Now plug in y=-2 and solve for x

x+2y=-7
x+2(-2)=-7
x+(-4)=-7
x-4=-7
x=-3

So your solution would be (-3,-2).

1)

$3x-2y=14\n \n y=5x$

We know y's value. Let's plug it in the equation.

$y=5x\n \n 3x-2\cdot (5x)=14\n \n 3x-10x=14\n \n -7x=14$

Divide both sides by -7.

$x=-2$

Now we have x's value. Let's plug it in the equation to find y.

$x=-2\n \n y=5x\n \n y=5\cdot -2\n \n y=-10$

Solution,

(-2, -10)

2)
$x-2y=-2\n \n y=2x+4$

Again we have y's value. Let's plug and solve.

$y=2x+4\n \n x-2\cdot (2x+4)=-2\n \n x-(2\cdot 2x+2\cdot 4)=-2\n \n x-4x-8=-2\n \n -3x-8=-2\n \n -3x=-2+8\n \n -3x=6\n \n x=\frac { 6 }{ -3 } \n \n x=-2$

Now we have x's value let's solve for y.

$x=-2\n \n y=2x+4\n \n y=2\cdot (-2)+4\n \n y=-4+4\n \n y=0$

Solution,

(-2, 0)

3)

$x+2y=-7\n \n x-5y=7$

Let's first multiply the first equation by -1

$-1\cdot (x+2y)=-1\cdot -7\n \n -x-2y=7$

Then let's add these new equation and the second equation.

$-1\cdot (x+2y)=-1\cdot -7\n \n -x-2y=7\n \n x-5y=7\n \n (-x-2y)+(x-5y)=7+7\n \n -x+x-2y-5y=14\n \n -7y=14\n \n y=\frac { 14 }{ -7 } \n \n y=-2$

Now we have y's value let's plug it and solve for x.

$y=-2\n \n x+2y=-7\n \n x+2\cdot (-2)=-7\n \n x-4=-7\n \n x=-7+4\n \n x=-3$

Solution,

(-3, -2)

Compare the values of the underlined digits 6,300 and 530 with three being the underlined digit.

Answers

The value of 3 in 6300 is ten times the value of 3 in 530

Further Explanation

Place value and total value

Place value refers to the value represented by a digit in a number based of its position in the number. Place values can be ones, tens, hundreds, thousands, etc

For example;

In the number; 13,548, the place value of the digits in the number are;

Ones -8

Tens - 4

Hundreds - 5

Thousands - 3

Ten Thousands – 1

Total value

Total value is given as the product of the digit and its place value.
For example; in the number, 13,548.
Total value of digits 1, 3, 5, 4, and 8 in the number 13,548 will be;

1 x 10,000 = 10,000

3 x 1000 = 3,000

5 x 100 = 500

4 x 10 = 40

8 x 1 = 8

The sum of the total values of digits in a number will be equivalent to the value of that number.

In the question.

Comparing the value of 3 in 6,300 and 530

The value of 3 in 6,300 is 300 and

The value of 3 in 530 is 30

Therefore; the value of 3 in 6300 is ten times the value of 3 in 530

Topic: Place value and total value

Comparing the values of 3 in each of 6,300 and 530, we will have:

3 in 6300 is 3 hundreds while 3 in 530 is 3 tens

How to solve number place value?

Place value is defined as the value of each digit in a number. For example, the 5 in 853 represents 5 tens, or 50; however, the 5 in 5,003 represents 5 thousands, or 5,000.

We want to compare the values of 3 in each of the numbers 6,300 and 530.

Thus, we can say that:

3 in 6300 is called 3 hundreds while 3 in 30 is called 3 tens or 30

Simplify.–1 + 5(6 – y)

A.

–y + 5

B.

–y + 29

C.

–5y + 29

D.

–5y – 31

Answers

The answer is C. This is because you have to expand the brackets
-1+5(6-y)
The -1 remains the same but the bracket changes.
-1+30-5y
This is because the 5*6 is 30 and 5*y is 5y
This can be simplified to
29-5y or -5+29
