Ivan works as a tutor for $8 an hour and as a waiter for $7 an hour. This month, he worked a combined total of 89 hours at his two jobs. Let t be the number of hours Ivan worked as a tutor this month. Write an expression for the combined total dollar amount he earned this month.

t+623

Step-by-step explanation:

If t is the number of hours Ivan worked as a tutor this month, you can say that the number of hours that Ivan worked as a waiter would be the result of subtracting the amount of hours he worked as a tutor this month from the combined total of hours he worked, which is:

89-t

After this, you can say that the combined total dollar amount Ivan earned this month is the result of adding up what he earned as a tutor plus the amount he earned as a waiter which is equal to 89-t. So, you would have:

8t+7*(89-t)

=8t+623-7t

=t+623

This means that the expression for the combined total dollar amount he earned this month is: t+623

just find the gcf and solve the gcf's until you get each answer i have a really good feeling somethings missing xd (like the dimensions of the fence) *cough *cough *hint *hint

step-by-step explanation:

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
