Step-by-step explanation:
Claim: There's 14 Goats and 9 Chickens!!
Data:
Working with the Provided Information.
Let the Number of goats be x
let the Number of Chickens be y
x + y = 23..... (i)
Since the goat Possesses Two Pair of Legs... Which is a Total of 4 Legs... We say Let its Contribution be 4x.
The Chicken has Only a Pair Of Legs...Which is a total of 2 legs.... We say let its contribution be 2y
4x + 2y = 74 .....(ii)
BRINGING BOTH EQUATIONS TOGETHER.
x + y = 23
4x + 2y = 74
From Eqn i
x= 23 - y
Substitute into eqn ii
4(23 - y ) + 2y = 74
92 - 4y + 2y = 74
92 - 2y = 74
2y = 92 - 74
2y = 18
y= 9.
Substitute y into any of the eqns to get x
x + y = 23
x + 9=23
x = 23 - 9
x = 14
This simply proves that there are 14 Goats and 9 Chickens!!!.
HAVE A GREAT DAY!
Answer:
There is a 9/15 or 3/5
Step-by-step explanation:
There are a total of 15 cards, of those, 6 are red, so if you subtract 6 from 15, you get 9, which is the total amount of yellow and blue cards, which is what you were to not get a red card.
Answer:
the answer is 14/27

Hello from MrBillDoesMath!
Answer:
l = s/3.14 - r^2
Discussion:
s = 3.14 l + 3.14 r^2 => divide both sides by 3.14
s/3.14 = l + r^2 => subtract r^2 from both sides
(s/3.14) - r^2 = l
Thank you,

Answer:
If the line is straight pointing diagonally to the top right corner then it is a proportinal relationship.
Step-by-step explanation:
if the line is diagonally upwards to the right, then if x increase, y increases, and if x decreases, then y increases.
for an equation, x must be positive. for example
y=-2x is not proportional but y=3x is
for the question in the photo the equation is y=x
