Answer:
Step-by-step explanation:
You can simplify this by collecting the like terms. The only like terms are the pair 2x and 18 x
2x-18x = -16x
Now, put them back together,
-16x + 14y-19
3 cm on the map represents 31.5 km in reality.
3cm : 31.5 km
1cm : 31.5/3 km
1cm : 10.5km
So the scale on the map is 1cm represents 10.5 km.

Step-by-step explanation:
I can't see picture very well but as I see first angle is
-4x+5 and second is -13x+39 ( if it isn't, correct me)
sum of this angles is 180° because they are inner angles
(-4x+5) + (-13x+39) = 180
-4x+5 -13x+39=180
-17x+44=180
-17x = 180-44
-17x= 136
x= -8
angle -4x+5 will be:
-4*-8 + 5= 32+5= 37°
Answer:
4 weeks= $57
45+3(4)
45+12=57
10 weeks= $75
45+3(10)
45+30=75
15 weeks= $90
45+3(15)
45+45=90
20 weeks=$105
No there is not enough money because you are $20 short after 20 weeks. You need to wait 7 more weeks
