The right side has the apex of the roof on it, point (5,5). From the picture we see its slope is -1. It has to be the negation of the left slope for a symmetrical roof.

Point slope form tells us

y - b = m (x - a)

y - 5 = -1 (x - 5)

y = -x +5 + 5

y = -x + 10

Answer: y = -x + 10

7 times the number of cookies in the jar plus 5 more from the tray is 54. How many cookies are in the jar?

Digiron [165]

Answer:

The number of cookies in the jar is 7.

If we include the 5 cookies from the tray in the jar the total number of cookies would be 5 + 7 = 12

Step-by-step explanation:

Consider the number of cookies in the jar as 'x'. Hence the equation formed would be:-

7(x) + 5 = 54

7x + 5 = 54

7x = 54 - 5

7x = 49

x = $\frac{49}{7}$

x = 7

The number of cookies in the jar is 7.

If we include the 5 cookies from the tray in the jar the total number of cookies would be 5 + 7 = 12

Hope this helps.

Once you do that you get $21 per hour.

You multiply 21 by 30 to know how much you'd be paid for working 30 hours.

You get your final answer which is $630.
