Answer: x = cost of games
y = cost of console
---
x + y = 540
x = 3y
---
put the system of linear equations into standard form:
---
x + y = 540
x - 3y = 0
solution:
x = cost of games = $405
y = cost of console = $135
Answer:
$15700
Step-by-step explanation:
To find the cost, you multiply $50 by the area of the floor. The floor must be a circle ("radius"), so to find the area of a circle, use the formula
Multiply 314 sq. ft. by the cost per sq. ft.
314 x 50 = 15700
Answer:
65
Step-by-step explanation:
Part one is always the ones 'in these: ( )'. 12/3=4 4*2=8. So now it is 8^2+8-7. 8^2 is 8*8=64. 64+8-7=64+1=65
