The grouping has changed in the equation.
3(mn) = (3m)n
This is the associative property of multiplication.
Answer:
Infinate solutions
Step-by-step explanation:
You’d use elimination
so you’d want to get either the x values to be the same or the y values so in this case we can multiply the top equation (4x + 6y=7) by 3 and then subtract the two equations so, 3(4x+6y=7) = 12x + 18y = 21 which is the same as the other equation meaning If you subtract the two you get 0=0 which leaves you with infinite solutions.
You're on the right track. After you get both equations you need to cancel one of the variables. In this situation, it doesn't matter which variable you cancel out.
1/2 is the simpliest form,divide everything by 2
Answer:
$3600
Step-by-step explanation:
In each case, the repair cost exceeded the deductible, so your out-of-pocket cost for 2 repairs is ...
2 × $1050 = $2100
In addition, you had to pay the premium of $750 per 6-month period, or $1500 per year, so your total was ...
$2100 +1500 = $3600 . . . out-of-pocket total
