Answer:
9 pigs
Step-by-step explanation:
We have the following numbers of heads:
pigs (p) + chickens (c) = 16 animal heads (1)
And the following numbers of feet:
4p + 2c = 50 animal feet (2)
From equation (1):
p = 16 - c (3)
By entering equation (3) into (2) we have:
4(16 - c) + 2c = 50
64 - 4c + 2c = 50
c = 7
Now, entering the value of c into equation (3) we have the next value of p:
p = 16 - c
p = 16 - 7
p = 9
Therefore, the number of pigs that Henry has is 9.

Answer: the first question is 9 -3/2y and the second one is 31 - 7y
Step-by-step explanation:
on the first one you move the variable to the right and divide by 2 and on the second one you can only move the variable to the right because you don’t know x to solve the entire equation! hope this helps

Step-by-step explanation:
Answer:
C
Step-by-step explanation:
NQP is a triangle. It has 3 angles given.
We know
<em>sum of 3 angles in a triangle is 180 degrees</em>
<em />
We are Given:
∠N = 2x
∠Q = 2x + 2
∠P = 134
THus, we can write and solve for x first:
∠N + ∠Q + ∠P = 180
2x + 2x + 2 + 134 = 180
4x + 136 = 180
4x = 180 - 136
4x = 44
x = 44/4
x = 11
Now, measure of ∠NQP is 2x + 2, so substituting the value of "x", we have:
2x + 2 = 2(11) + 2 = 22 + 2 = 24 degrees
So,
∠NQP = 24°
Correct answer is C
