Answer:
c
Step-by-step explanation:
Given the 2 equations
x + y = 3 → (1)
3x - y = 1 → (2)
Adding the 2 equations term by term will eliminate the term in y
4x = 4 ( divide both sides by 4)
x = 1
Substitute x = 1 into either of the 2 equations and evaluate for y
Substituting into (1)
1 + y = 3 ( subtract 1 from both sides )
y = 2
Solution is (1, 2 ) → c
Answer:
g = 55
f = 55
h = 55
Step-by-step explanation:
g = 180 - 25 = 55
this is because angle on a straight line is equal to 180 degrees
f = 55
alternate angles are equal. f alternates g
h = 55
opposite angels are equal
Answer:
yd^2
Step-by-step explanation:
Formula: 
p = 7.5 + 7.5 = 15
q = 13 + 13 = 26

A = 195
This would be:

Using common denominator of 6:

They should use
