Answer:
148
Step-by-step explanation:
180 - 32 = 148
both angles together make 180
1 Yes 2. Yes
Step-by-step explanation:
they are similar because in problem one each side is related by a factor of 3
in problem 2 each side is related by a factor of 2.
Step-by-step explanation:
4. 4(x+1) = 12
4x+4 =12
4x = 12/4
4x = 3
x = 3/4
Linear.
2x + 5y = 10
5y = -2x + 10
y = -2/5 x + 2 - Linear
Inverse variation means y = k/x, right? Your question is why can't x = 0. Answer - you're not allowed to divide by 0.
