Answer:
136.015 yd
Step-by-step explanation:
Length of diagonal is:
√( (80 yd)² + (110 yd)² ) = √( 18500 yd² ) = 136.015 yd
Answer:
Variables:
x - group lessons
y - private lssons
The systems of equations to represent the problem:
12x+3y=132
10x+2y=100
Solution:
The cost for private lessons is $200
Step-by-step explanation:
x is the number of group lessons
y is the number of private lessons
multiply 12x+3y=132 by 5
multiply 10x+2y=100 by -6
so now the two equations you have are
60x+15y=660
-60x+-12y=-600
add the two equations together and you get
3y = 600
now solve for y:
y=200
