Answer:

5/7

Step-by-step explanation:

- 3/7 × - 1 2/3 =

[a b/c = ac + b / c]

-3/7 × -5/3 [convert the mixed fraction to an improper fraction in order to multiply the numerator and denominator directly]

=

(-)(-)15/21 =

[2 negatives make a positive]

15/21 =

5/7

a/b × c/d = a × c/b × d = ac/bd

[reduce until the denominator or numerator is prime (only divisible by 1 and itself)]

Answer:

5/7

Step-by-step explanation:

-3/7 x -1  2/3

Convert to improper fraction:

3 x 1 = 3

3 + 2 = 5

-1 2/3 = -5/3

-3/7 x -5/3 = 15/21 = 5/7

Both fractions are negative, so the answer will be positive!

Answer:

x = 20º

Step-by-step explanation:

7x + x + 20 = 180

8x + 20 = 180

8x = 180 - 20

8x = 160

x = 160 / 8

x = 20

Answer:

X=20

Step-by-step explanation:

When you add 7x and the x+20, they total to 180 degrees to form a flat angle so to solves this use equation 7x+x+20=180 to get x=20.

To check: input the 20 into both equations and see if they add up to 180 degrees

7x20=140

20+20= 40

140+40= 180

Answer:

Step-by-step explanation:

a^2+b^2=c^2

y^2+8^2=17^2

Step 1: Simplify both sides of the equation.

y^2+64=289

Step 2: Subtract 64 from both sides.

y^2+64−64=289−64

y^2=225

Step 3: Take square root.  

y=15

Answer:

Step-by-step explanation:

Answer:

1. X^2+1/2x = [tex]x(x+\frac{1}{2})[/tex]

2.  X^2+2x-3 = [tex](x-1)(x+3)[/tex]

3. (2x-3)^2 = (2x-3)(2x-3)

4. X^3+2x^2-19x-20 = [tex](x+1)(x-4)(x+5)[/tex]

Step-by-step explanation:

Each expression can be written as a product of linear factors as follows

1. X^2+1/2x ⇒ [tex]x^{2} + \frac{1}{2}x[/tex]

[tex]x^{2} + \frac{1}{2}x[/tex] = [tex]x(x+\frac{1}{2})[/tex]

Hence,  X^2+1/2x = [tex]x(x+\frac{1}{2})[/tex]

2. X^2+2x-3 ⇒ [tex]x^{2} +2x-3[/tex]

[tex]x^{2} +2x-3 = x^{2} +3x-x-3[/tex]

[tex]x^{2} +3x-x-3 = x(x+3) -1(x+3)[/tex]

[tex]x(x+3) -1(x+3) = (x-1)(x+3)[/tex]

Hence,  X^2+2x-3 = [tex](x-1)(x+3)[/tex]

3. (2x-3)^2 ⇒[tex](2x-3)^{2}[/tex]

[tex](2x-3)^{2} = (2x-3)(2x-3)[/tex]

Hence, (2x-3)^2 = (2x-3)(2x-3)

4. X^3+2x^2-19x-20 ⇒ [tex]x^{3}+2x^{2} -19x -20[/tex]

[tex]x^{3}+2x^{2} -19x -20 = (x+1)(x^{2} +x-20)[/tex]

First,

[tex]x^{2} +x-20 = x^{2} +5x-4x-20\\x^{2} +5x-4x-20= x(x+5)-4(x+5)\\x(x+5)-4(x+5) = (x-4)(x+5)[/tex]

∴ [tex](x+1)(x^{2} +x-20) = (x+1)(x-4)(x+5)[/tex]

Hence, X^3+2x^2-19x-20 = [tex](x+1)(x-4)(x+5)[/tex]

The answer for first equation is, option B.

and the Answer for Second equation is option D.

Answer:

x=20

Step-by-step explanation:

so we just mark ADB as 45 and BDC as 50 and now we can find B and C by doing 180-50=130/2 so B=65 and C=65 now we have 2 angles so we can find x. D is 95 bc we add 45 and 50 and C is 65 like i wrote there so we add 95+65 and get 160 and we subtract 160 from 180 to get x=20

Divisibility rule of 2-last digit divisibility

Divisibility rule of 3-sum of digit divisibility

Divisibility rule of 4-last 2 digits divisibility

Divisibility rule of 5-last digit 0 or 5

Divisibility rule of 6-divisible by both 2 and 3

Divisibility rule of 9-sum of digits divisibility

Divisibility rule of 10-last digit 0

Now we can see that last digit 6 is divisible by 2

2+6+1+6=15 is divisible by 3

16 is divisible by 4

6 is not 0,5 so 2616 is not divisible by 5

2616 divisible by both 2 and 3 so its divisible by 6

2+6+1+6=15 is not divisible by 9

6 is not 0 so 2616 is not divisible by 10

Hope it helped!

Step-by-step explanation:

Remark

This is just an ordinary Pythagorean Problem.

a = 32

b = 24

c = ?

Distance

a^2 + b^2 = c^2

32^2 + 24^2 = c^2

1024 + 576 = c^2

c^2 = 1600

√c^2 = √1600

c = 40

c =  40 The distance the trains are apart is 40 km

Answer:

Each term in Pattern A is equals to 6 times the value of corresponding term in Pattern B and subtract 12

Step-by-step explanation:

Given - Pattern A: start with 12 and add 12

             Pattern B: start with 4 and add 2

To find - Which statement best describes the relationship between the

              corresponding terms of Patter A and Pattern B.

Proof -

To find the relationship between the Pattern a and pattern B , firstly we have to find few terms of both the Patterns , so that we can see how the digits of both the Patterns are realted

Now,

For Pattern A :

1st digit = 12

2nd digit = 12 + 12 = 24

3rd digit = 24 + 12 = 36

4th term = 36 + 12 = 48

5th term = 48 + 12 = 60

.

.

.

and so on

Now,

For Pattern B :

1st digit = 4

2nd digit = 4 + 2 = 6

3rd digit = 6 + 2 = 8

4th term = 8 + 2 = 10

5th term = 10 + 2 = 12

∴ we get

Terms of Pattern A : 12, 24, 36, 48, 60, ....

Terms of Pattern B :  4, 6, 8, 10, 12, ....

As we can see that

4×6 - 12 = 12

6×6 - 12 = 24

8×6 - 12 = 36

10×6 - 12 = 48

12×6 - 12 = 60

.

.

The pattern is - Multiply by 6 in Pattern B and after that subtract by 12 , we get Pattern A.

Term in Pattern A = 6×corresponding term of Pattern B - 12

i.e. , we get

Each term in Pattern A is equals to 6 times the value of corresponding term in Pattern B and subtract 12
