Step-by-step explanation:
You have to know how negative exponents "work" to understand this concept.
because if you want to make a negative exponent positive you put what the exponent is on under a 1. It follows then that you can go backwards from that and rewrite positive fractions with negative exponents.
The odd numbers between 142 and 156 are these:
143, 145, 147, 149, 151, 153, and 155.
Of these, 143 to the nearest ten is 140.
Likewise, 151 to the nearest ten is 150.
And, 153 to the nearest ten is 150.
Of the seven original numbers, 143, 151, and 153 round to a nearest ten that
is less than the possible mystery number.
To the nearest hundred, 143 goes to 100; 151 goes to 200, and 153 goes to 200.
Of those three, only two round to a nearest hundred that is bigger than the mystery number.
Answer: 151 and 153 are the mystery numbers.
Answer:
Alina owes $4 to Mya and Mylana owes $1 to Mya and $1 to Genesis.
Step-by-step explanation:
As they want to share the party expenses equally, first you have to add all the expenses and divide them by 4 people to know the amount that each person has to pay:
$21+$25+$16+$18= $80/4= $20
As everyone has to pay $20 for the party expenses, we can see that Genesis spent $1 more and Mya $5 more, so they have to get the money back from the other 2 people.
Alina owes: $20-$16= $4. She owes $4 to Mya as she will pay the entire amount she owes to one person and Mya has to get $5 back.
Mylana owes: $20-$18= $2. She would have to pay $1 to Mya to complete the $5 she had to get back and $1 to Genesis.
