The coefficient is a number before a variable.
Here, the coefficient is 9.
The like terms are any terms that have the same variable.
Here, 9k and -k are like terms, and 7 and 4 are like terms as well.
Combine like terms:
8k+3
The constants are: 7 and 4 (Constants are numbers in an expression or equation)
After combining like terms, the constant became
3
Answer: x-10
Step-by-step explanation: 3x*2x= 10x; 3x*(-5)= -15x; 2*2x= 4x; 2*(-5)= -10
Answer:
80 ft
Step-by-step explanation:
Distance = rate x time. Therefore, 20 ft / min x 4 min = 80 ft.
<em>x = 4</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em>use </em><em><u>Thales theorem</u></em>
<em>x/(x + 8) = 4/12</em>
<em>12x = 4x + 32</em>
<em>12x - 4x = 32</em>
<em>8x = 32</em>
<em>x = 32 : 4</em>
<em>x = 4</em>
<em />
<em>4/(8 + 4) = 4/12</em>
<em>4/12 = 4/12 (true)</em>
<em />
<em>Good luck !</em>
The answer is 6.6 because it’s the only number between 6.5 and 6.7 so 6.6 is your answer
