Answer:
w = 2 He bought 2 packages of white socks
Step-by-step explanation:
6(8) + 4w = 56
48 + 4w = 56
4w = 8
w = 2
Check your work
6(8) + 4(2) = 56
48 + 8 = 56
56 = 56

Answer:
x = 5 , y = 2
Step-by-step explanation:
5x + 2y = 29 ....................(1)
x + 4y = 13 Multiply this equation by -5:-
-5x - 20y = -65.................(2)
Add equations (1) and (2):-
-18y = -36
y = 2
Substitute for y in equation (1):-
5x + 2(2) = 29
5x = 25
x = 5
Check the results in the second equation:-
x + 4y = 13
5 + 4(2) = 13 - It checks out.
Answer:
60
Step-by-step explanation:
We are given the triangles are congruent, that means the angles are the same measurement
<A = <X
<B = <Y
<C = <Z
We know A = 50 so X = 50
We know <Y = 70 so < B = 70
The three angles of a triangle add to 180
<A + <B + <C = 180
Substituting into the equation
50 + 70 + <C = 180
Combining like terms
120 + <C =180
Subtracting 120 from each side
120-120 +<C =180-120
<C = 60
