The work of a student to solve the equation 3(3y - 8) = 10 + 3y is shown below: Step 1: 3(3y - 8) = 10 + 3y
Step 2: 6y - 5 = 10 + 3y
Step 3: 3y - 5 = 10
Step 4: 3y = 15
Step 5: y = 5
In which step did the student first make an error and what is the correct step?
Step 2: 9y - 24 = 10 + 3y
Step 2: 6y + 11 = 10 + 4y
O Step 3: 6y - 8 = 3(6 + y)
O Step 3: 3(3y - 8) = 7 + y
You must check the box below prior to submitting your exam!

Step 2; error

Step-by-step explanation:

The correct; 9y-24=10+3y

9y-3y=24+10

6y=34

y=5.66

answer: 1inch=7days  

12inch=12*7=84days

step-by-step explanation:

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!
