You can square the whole problem to cancel out the square root. Might make things easier.
Answer: 102 children and 41 adults swam at the pool that day.
Step-by-step explanation:
Let x represent the number of children that swam at the public pool that day.
Let y represent the number of adult that swam at the public pool that day.
On that certain hot summer's day, 143 people used the public swimming pool. It means that
x + y = 143
The daily prices are $1.25 for children and $2.25 for adults. The receipts for admission totaled $219.75. It means that
1.25x + 2.25y = 219.75- - - - - - - - -1
Substituting x = 143 - y into equation 1, it becomes
1.25(143 - y) + 2.25y = 219.75
178.75 - 1.25y + 2.25y = 219.75
- 1.25y + 2.25y = 219.75 - 178.75
y = 41
x = 143 - y = 143 - 41
x = 102
Cassie misplaced her card because the question states she had her card on -2 2/3, which would be past the -2. However, Cassie put her card on -1 2/3 instead of -2 2/3. Try and look at point C again to see her mistake.
Post brainliest if this helped :D
<span> 32=2^5
^ = "to the power of"
1/32=1/2^5
1/2^5=2^-5
so
1/32=2^-5 </span>
could u give me more detail?
(like y’s number)
