Answer:

Henry was thinking of the number 10.

Step-by-step explanation:

Variable x = Henry's original number

Set up an equation:

x ÷ 2 + 10 = 15

Isolate variable x:

x ÷ 2 = 5

x = 10

Taylor is using money from her coin try to go to the fair. She wants to spend no more than $17 there. She has $8 in bills and so
ZanzabumX [31]
There are 4 quarters in dollars. Keep that in mind.

Since Taylor is spending no more than 17 dollars, she probably only has 17 dollars. We already know that she has 8 dollars in bills, so we can subtract 8 dollars from 17 dollars because we need to find the amount of dollars in quarters. 

The answer for that is 9 dollars. Since there are 4 quarters in the dollars, you need to multiply 9 by 4 to find the amount of quarters.

How do I find Q15 c, d and e???
klasskru [66]
I would make a tree because there are not that many possibilities. to get 99 with numbers between 1 and 50 you have 50+49 and 49 and 50 nothing else will work because if one spin is less than 49 say 48 to get 99 you need 51 which is impossible. either you 50 then 49 or you get 49 then 50. the others are a bit harder because you need to find all possible spins that will sum to 52 which is a much larger number.
