30 x 0.33 = 9.90 And that's the answer
15+5•y/2
15+5•4 / 2
15+20 / 2
15+10
=25
He can make 18 and then he wouldn't have enough to make that 19th. You just take 28 and multiply it by 2, then divide it by 3. Or just multiply 28 by 2/3
Step-by-step explanation:
<u>Missing reasons:</u>
- 1. Given
- 2. Definition of congruence
- 3. Linear pair postulate
- 4. Supplementary angles postulate
- 5. Definition of linear pair
- 6. Substitution property of equality
- 7. Supplementary angles postulate
Supposing all were child tickets:
145x$5=$725
$1153-$725=$428 (diff. between above price and original price)
$9-$5=$4 (diff. between adult price and child price)
$428÷$4=107 (no. of adult tickets)
Ans: 107
