Answer:
31. 122
32. 2400 cans
Step-by-step explanation:
31.
fig 1=1
fig 2=10
fig 3=26
fig 4=50
fig 5=82
fig 6=122
32. 520/13=40
40(60)=2400
2 x = y + 3 , 4 x − 3 = 2 y
Rewrite the equation as y + 3 = 2 x . y + 3 = 2 x 4 x − 3 = 2 y Subtract 3 from both sides of the equation.
y = 2 x − 3 4 x − 3 = 2 y Rewrite the equation as 2 y = 4 x − 3 . y = 2 x − 3 2 y = 4 x − 3 Divide each term by 2 and simplify.
y = 2 x − 3 y = 2 x − 3 2 Create a graph to locate the intersection of the equations.
The intersection of the system of equations is the solution. No solution
