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.
The answer i got is 44/3 but as a mixed number it’s 14 2/3
Answer:
x=7
y=2
Step-by-step explanation:
10 + 2x = -2y ➡y = -5-x
replace y with -5-x in the first equation
-5-x-x = 9➡ -2x-5 = 9 ➡-2x = 9+5 ➡ x = -7
now use this information to find value of y
y - (-7)=9 ➡y = 2
Answer:
i belief the answer is 15
Step-by-step explanation:
cause 20 percent of 75 is fifteen
Point-slope form is y - y1 = m (x + x1)
First you need to find m [slope] by subtract y2 and y1 and divide it by the outcome of x2 - x1
13 - (-9) = 22
-2 - 9 = -11
22/-11 = -2
Plug in the first point (as instructed) into the equation.
y - (-9) = -2 (x - 9)
Simplify the beginning.
y + [9] = [-2] (x + [-9])
