Answer:
Step-by-step explanation:
Since the boys collected 16 cans each and there are 12 of them it means they collected 16*12= 192 cans in total
there are 15 girls and each collected 14 cans. Therefore they collected 15*14=210 cans in total
210-192=18 cans the girls collected more than the boys
Answer:
y = -2x - 3
Step-by-step explanation:
11.p=-8, 17-8=9
12.y=11, 3*11=33+16=46
13.t=4, 4*4=16-14=2
14.x=9, -9x 9*8=82-9=72-9=62
15.z=4, 12*4=48-18=30
16.g=0, 4*0=0, 7+0=7
17.x=4, 9*4=36-24=-3
18.q=3, 18*3=48+2=50
19.c=2, 3*2=6-4.5=4.1
20.y=4, 9+4=13+4.8=17.4
If it is just the decimal 3.1415 then it is rational. If it is pi it is irrational
