Answer:
Step-by-step explanation:
We can write two equations in the two unknowns using the given relations. Let g and b represent the costs of a round of golf and a turn in the batting cage, respectively.
5g +4b = 60 . . . . . Sylvester's expense
3g +6b = 45 . . . . . Lin's expense
Dividing the second equation by 3 gives ...
g +2b = 15 ⇒ 2b = 15 -g
Substituting into the first equation, we have ...
5g +2(2b) = 60
5g +2(15 -g) = 60 . . . . . substitute for 2b
3g = 30 . . . . . . . . . subtract 30, collect terms
g = 10 . . . . . . . divide by 3
__
2b = 15 -10 = 5 . . . . use the value of g to find b
b = 2.5 . . . . . . . . divide by 2
Mini golf costs $10 per round; batting cages cost $2.50 per turn.
Answer:
what is your question though. if its create an equation, its
y = 1/6x + 2
Answer:
37 kilograms alr recycled this year
Plan:
1 kilogram each week
After 13 weeks he would of recycled 13 kilograms
37+13=50
In total his office wesley's have recycled 50 kilograms of paper
Hope this helps
1/2^-2 Can be written as 2^2
Therefore , 2×2=4
9 is the answer 15-6 is 9
