201 - immigrant
221 - indigenous
Add 10 to indigenous and subtract 10 from immigrant.
Our problem becomes 4x-1=3x+6 To solve this, we need to get all of the x's on one side, we are going to subtract 3x to do that. We end up with:
x-1=6
Now we just need to get rid of the -1 and we're home free. We get rid of that -1 we just add one
x=7
Any questions?
The total weight is 157.5 pounds. 11.25 x 12 is 135. 135 plus 22.5 is 157.5
Answer:
Number of cinammon = 12
Number of chocolate = 21
Step-by-step explanation:
Given that:
Cost of Cinnamon candle , c = $3.50
Cost of chocolate candle , d = $2.50
Total amount raised, T = $94.50
d = 2c - 3
Total amount = (cost of Cinnamon * number sold) + (cost of chocolate * number sold)
94.50 = (3.50 * c) + (2.50 * (2c-3))
94.50 = 3.50c + 5c - 7.5
94.50 = 8.50c - 7.5
94.50 + 7.5 = 8.50c
102 = 8.50c
c = 102 / 8.50
c = 12
d = 2c - 3
d = 2(12) - 3
d = 24 - 3
d = 21
Answer:
Travis should pick to play the hat game.
Step-by-step explanation:
You would need to evaluate the probablity of winning in each option
Option 1 (rolling die)
p(roll 2 or 3)=2/6
p(roll 2 or 3)=1/3=.33
Option 2 (pick letters)
p(pick A or B) = 2/5
p(pick A or B) = .4
.33<.4
Since option 2 with picking letters has a higher chance of winning, then Travis should play the second game to win the goldfish as a higher chance of winning makes it easier for him to win the prize.
