I think it is 96 but I could be wrong
7. q+18 =22
q+18-18 =22-18 , q=4
at the problem q+18-18=22+18 mistake (should be subtracted from both sides)
8. r+10-10=22-10 r=12
r-15+15=5+15 r=20
r-18+18=14 +18 r=32
r+5-5=15-5 r=10
Answer: $75 per night and $15 per meal
Step-by-step explanation:
Hello there!
If DEF = 18, we then use the sin method, or the law of sin.
18 divide by sin90 would be F = sin45 .
We therefore end up with 12.72 but rounded would be 12.7 as 2 is lower than 5, so, it just rounds back down to 7.
Your answer: 12.7
