Answer: Keep change change are used in division, like if I had 10 divided by -5 I would keep the 10 change division to multiplication and change the 5 to a positive : 10 X 5

KCF, when doing a division fraction problem, you keep the first fraction, change the division into multiplication, and flip the other fraction. For example:
1/4 / 4/7
turns into
1/4 x 7/4
it makes it easier to solve

Hemework -13 . <br>Express the ratio 20cm to 15m in the form 1:n <br>

ankoles [38]

Answer:

1: 75

Step-by-step explanation:

20cm : 15m

Convert meters to cm

1 meter = 100 cm

15m = 15 x 100 = 1500 cm

20cm:1500cm

Divide both sides of the ratio by 20

=> 1 : 1500/20 = 1: 75

Solve. z – 9 = 27 a. 3 b. 16 c. 18 d. 36

Rashid [163]

$z - 9 = 27$

$z - 9 = 27:z$

$z=27+9$ $| Combine \ like \ terms|$ $|Add \ 9 \ to \ both \ sides|$

$z=36$

What is the distance between the following coordinates? Show work.

miss Akunina [59]

Answer:

$\huge{ \boxed{ \bold{ \tt{2 \sqrt{26}}} \: \: \text{units} } }$

<h3>♁ Question :</h3>

Find the distance between ( 5 , -6 ) and ( 3 ,4 ).

<h3>♁ Step by step explanation:</h3>

Let the points be A and B. Now,

Let, A ( 5 , -6 ) ⇢ ( x₁ , y₁ )
Let, B ( 3 , 4 ) ⇢ ( x₂ , y₂ )

Use the distance formula to determine the distance between A ( 5 , -6 ) and B ( 3 , 4 ).

$\boxed{ \underline{ \sf{distance = \sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} } }}}$

Substitute the actual value of the points into the distance formula and then simplify.

$\dashrightarrow{ \sf{ \sqrt{ {(3 - 5)}^{2} + {(4 - ( - 6))}^{2} } }}$

Remember : The positive and negative integer are always subtracted but posses the sign of the bigger integer.

$\dashrightarrow{ \sf{ \sqrt{ {( - 2)}^{2} + {(4 - ( - 6))}^{2} } }}$

Remember : ( - ) × ( - ) = ( + )

$\dashrightarrow{ \sf{ \sqrt{ {( - 2)}^{2} + {(4 + 6)}^{2} } }}$

Add the numbers : 4 and 6

$\longrightarrow{ \sf{ \sqrt{ {( - 2)}^{2} + {(10)}^{2} } }}$

Evaluate the power

$\longrightarrow{ \sf{ \sqrt{4 + 100}}}$

Add the numbers : 4 and 100

$\dashrightarrow{ \sf{ \sqrt{104}}}$

$\dashrightarrow{ \boxed{ \sf{2 \sqrt{26} }}}$ units

Therefore , The distance between ( 5 , -6 ) and ( 3 , 4 ) is $\sf{2 \sqrt{26}}$ units .

And we're done!

Hope I helped!

Have a wonderful time ! シ
