So you multiply 13 by each variable and it’s coefficient.
13n+52+91m
Answer:
0.00144
Step-by-step explanation:
(13/1)(4/3)(12/1)(4/2)/(52/5)=(13)(4)(12)(6)/2598960=3744/2598960≈0.00144
Answer:
x = -3 or 9/4
Step-by-step explanation:
(x+3)(4x-9)
or use the quadratic formula
The number 1 is neither prime nor composite. A prime number is a whole number with two divisors. Since the number 1 only has 1 divisor, itself, it is not prime. A composite number is a whole number with more than two divisors, thus it is not composite with only one divisor.
Answer:
14x + 6y = 10
14x + 35y = -77
Step-by-step explanation:
Multiply the top one by 2
14x + 6y = 10
Multiply the bottom one by 7
14x + 35y = -77
His next step is to subtract. You could have done this by multiplying the top one by -2
-14x - 6y = - 10
14x + 35y = -77 Now all you need do is add. The question now becomes what do you do? What answer do you give? I think the expected answer is the top two equations, but if I was actually doing the problem, I'd use the bottom 2.
