Alrighty, so, if I remember correctly: For the first question you have 20 possible outcomes, 4 of which are multiples of 5. (5,10,15,20). This gives you 4/20, I multiplied both the numerator and denominator by 200 which then gave me 800/4000. Next I divided which gave me 0.2.
Answer:
2,175 calories
Step-by-step explanation:
140 pound person will use 2100 calories per day
145 pounds person will use x calories per day
Find x
Pounds : calories
140 : 2100 = 145 : x
140/2100 = 145/x
Cross product
140 * x = 2100 * 145
140x = 304,500
Divide both sides by 140
x = 304,500 / 140
= 2,175
Therefore,
145 pounds person will use 2175 calories per day
Nick = n
Ray = r
n=3r-30
n+r=74
3r-30+r=74
4r-30=74
4r=104
r=26
n=26*3-30
n=78-30
n=48
Nick is 48 years old and Ray is 26 years old
Hope this helps.
