You would need to know how much the arcade game cost and how much the Ferris wheel cost then let x represent the amount of times she played the arcade game and let y represent how many times she rode the ferris wheel.
once given the x and y you could figure out how much money she spent all together.
The answer is <span>d) 1/p + 1/r.
Solution to this is,
</span>[r(p-q)/p(q-r)]=1
pr-qr=pq-pr
2pr=pq+qr
2pr/pqr=(pq+qr)/pqr
2/q=1/r+1/p
The first picture about the 2 3/4 the answer is c. think of how 4 quarters can make a dollar, 3/4 being 3 quarters out of a dollar, then you can ask yourself how much is 3 quarters (.75) and with 2 being a whole it would leave you with 2.75 being equivalent to 2 3/4 <span />
No.
This rate of refusals seems quite low, actually. Some polls are lucky to get a 50% answer rate.
Answer:
D
Step-by-step explanation:
m + 9 can be +ve or -ve or 0.
m can be any number, even lesser than -9 to make it +ve. [-10+9 = -1 = -ve no.]
Or, maybe greater than -9 to make m+9 +ve. [-8 + 9 = 1 = +ve no.]
Or, maybe -9 only so that m+9 is 0
[ -9 + 9 = 0 ]
It can be -ve, +ve and 0 as well.
