75

Reduction of 12
3 x 4 = 12

Increase of 10
5 x 2 = 10

75 - 12 = 63
63 + 10 = 73

Change = 2 inches (75 - 73)

Answer:

73 inches

Step-by-step explanation:

First you calculate the the change separately. The change for 4 weeks would be...

Evaporation: -3x4=-12  

Adding water (every 2 weeks): 5x2=10

Then you add -12 + 10 = -2. There is a -2 inches change during 4 weeks. Finally you subtract 75 -2 = 73 inches.

Your welcome!

Find the angle measure of PQR
sineoko [7]

Answer:

<em>64 degrees</em>

Step-by-step explanation:

When you have the SRQ angle, you can easily solve for PQR. Luckily, we're given that QRP and PRS are 32 and 84, respectively. Adding this together gives you 116. 116*2 = 232 and 360-232 = 128, and 128/2 = 64.
