Use order of operations to solve: 15÷5+6-(12÷6) =

7

Step-by-step explanation:

15/5+6-(12/6)

15/5+6-(2)

3+6-2

9-2

7

the answer is 7

Step-by-step explanation:

the order of operation is

P= parentheses

E= exponent

M= multiplication

D= division

A= addition

s= subtraction

so that means first you do what is in the () so 12÷ 6= 2

now the next step would be divisions so that mean 15 ÷ 5 =3

now we have to put these two answers  back in to the equation 3+6-(2) then add 3 and 6 you should get 9 now subtract 2 and you get 7

if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!
