Third one :) i think i’m NEW to this app don’t hate me.
PEMDAS, notice Parentheses is first, then Exponents 2nd
now that the exponent got done, let's keep in the parentheses
PEMDAS, after all that we'll do D, Division next
--------------------------------------------------------------------------
this just some addition to your previous posting, since you kinda got spammed some
notice, PEMDAS, P first and so on, AS are last, from left to right.
Answer:
see explanation
Step-by-step explanation:
Given
10 = 7 - m ( subtract 3 from both sides )
3 = - m ( multiply both sides by - 1 )
- 3 = m , or
m = - 3
As a check
Substitute m = - 3 into the right side of the equation and if equal to the left side then it is the solution
7 - m = 7 - (- 3) = 7 + 3 = 10 = left side
Thus m = - 3 is the solution to the equation
25 - (3*3) - (3*5)
25 - 9 - 15
=1
Yes it is enough, and will have balance of 1g
