Hi! :) How are you?
I'm doing well but I would like to hear about you!
Answer:
23 tables
Step-by-step explanation:
4(4x+3)=19x+9-3x+3
4*4x 4*4 =19x+9-3x+3
16x+12= 16x+12
12=12
The snowplow's speed is 40 mph minus the loss from the snow, which is 1.2 mph times the depth of snow in inches.
y = 40 − 1.2x
When y = 0:
0 = 40 − 1.2x
1.2x = 40
x = 33 ⅓
The snowplow stops moving when the snow is 33 ⅓ inches deep or more.
-9
