Answer:
13
Step-by-step explanation:
because a is the missing number. Well, 21 minus or - 8 is equal to 13.
The point-slope form:

We have the points (3, -4) and (5, 1). Substitute:

The standard form: 
<em>multiply both sides by 2</em>
<em>use distributive property</em>
<em>subtract 2y from both sides</em>
<em>subtract 15 from both sides</em>

<h3>Answer: 5x - 2y = -7</h3>
Step-by-step explanation:
- 0.06
- 60%
- 2/3
- 3/4
hope it's right :)
First you need to know some rules 2 numbers that are the same with coefficients divided : you differentiate those coeff
and multyplied :you sum up them
12x^8/3x^3= 4x^8-3=4x^5
20^2x=20^x*20^x
m^5*m^-7=m^5-7=m^-2
Answer:
D
Step-by-step explanation:
Merhaba!

bir ayakkabı=495/3=165
Good work ;)
