Answer:
13 sheep, 19 chicken
Step-by-step explanation:
You can start to solve this problem by assigning variables. First, let's assign the number of sheep there are as and the number of chickens there are as .
Because each sheep has 4 legs, the number of legs for each sheep would be . Similarly, because each chicken has 2 legs, the number of legs for each chicken would be . Each animal would have 1 head, so the number of heads would just be and . Because the number of legs in total are 90, . Because the number of heads in total are 32,
There is now a system of equations with two unknown variables and two equations. There are many ways to solve this, but for me, the easiest would be elimination. First, I would double the second equation, . Then, I would subtract that from the first equation, eliminating . . Solving for x gives 13. We can then plug that value into the second equation, making y be . This means that and , meaning that there are 13 sheep and 19 chicken.
Hey there!
-11b + 7 = 40
- SUBTRACT by 7 on each of your sides.
-11b + 7 - 7 = 40 - 7
Cancel out: 7 - 7 because that gives you 0
Keep: 40 - 7 because it helps us solve for our answer
40 - 7 = 33
11b/-11 = 33/-11
Cancel out: -11b/-11 because it equals 1
Keep: 33/-11 because it gives you -3
33/-11 = 33 ÷ -11 = 3

Good luck on your assignment and enjoy your day!

Answer:
$21.60
Step-by-step explanation:
240 x .09 = 21.60
Candidate X won 63 out of the 100 "votes" of the poll participants.
So candidate X won 63% of the votes in the poll.
This means that candidate X is expected to win the elections by a percentage close to 63%.
63% of the voters is (63/100)*5000=63*50=3150 voters
Answer: 3150
