Lamar works as a tutor for $7 an hour and as a waiter for $8 an hour . this month he worked a combined total of 92 hours at his
ira [324]

t is the number of hours Lamar worked as a tutor 
We know that he worked for 92 hours total, so he worked 92-t hours as a waiter.

So his earnings are: 7t + 8(92-t) = 736 -t dollars

This expression seems logical as if Lamar worked 0 hours as a tutor and 92 as a waiter his earnings would be 8*92 = 736
If he worked as a tutor for 92 hours it would be 7*92= 644 
736-92= 644 
So our expression seems to be working.

Cy+4=d−9y solve for y
tiny-mole [99]

Answer:

Answer:

y= d−4 /c+9

Step-by-step explanation:

cy+4=d−9y

Step 1: Add 9y to both sides.

cy+4+9y=d−9y+9y

cy+9y+4=d

Step 2: Add -4 to both sides.

cy+9y+4+−4=d+−4

cy+9y=d−4

Step 3: Factor out variable y.

y(c+9)=d−4

Step 4: Divide both sides by c+9.

y(c+9)  c+9 = d−4 /c+9

y= d−4 /c+9

Tell whether the ordered pair is a solution to the equation please show how you solve it.
Orlov [11]

Answer:

The ordered pair is not a solution as both sides of the equation do not equal each other.  

Step-by-step explanation:

(3,2);  x + 6y = 13

(3) + 6(2) = 13

3 + 12 = 13

15 = 13
