Step-by-step explanation:
The coefficients of the y terms are -3 and 2. The least common multiple of 3 and 2 is 6. So multiply the first equation by 2 and the second equation by 3, so that the y terms have a coefficient of 6.
4x − 6y = 42
-18x + 6y = 21
The signs are opposite, so add the equations together.
-14x = 63
x = -9/2
Answer:
(18/m)-3
Step-by-step explanation:
Hi!
Well, if you're looking for an equation, it's (18/m)-3

Answer:
Step-by-step explanation:
The problem can be modeled by using the compound growth formula.
Given, Initial number P_0 of people who Nicholas sent the chain letter t=50
The growth rate, r =99%=0.99
Period of Growth,k =12 Weeks
Therefore, in any week (t) after Nicholas initially sent the mail, the number of people who receive the email is modeled by the function:
Answer:
Step-by-step explanation:
<u>The ratio is given:</u>
<u>Let each equal part be x, then we have:</u>
- b - r = 6
- 9x - 6x = 6
- 3x = 6
- x = 2
<u>Total number of counters:</u>
- 2(9 + 6 + 3) = 2(18) = 36
