Answer:
=−38/5
Step-by-step explanation:
Subtract 25 from both sides of the equation
5+25−25=−13−25
5=−13−25
5=−38
Divide both sides of the equation by the same term
5/5 =−38/5
which equal to =−38/5
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.
Answer:
$5.75
Step-by-step explanation:
50.24 - 38.74 is 11.5
Then, to find how much each potato bag is you need to divide by 2.
11.5 divided by 2 is 5.75.
Each bag of potatoes was 5.75$
21 x 9 = 9 x 21 is the commutative property.
