Answer:
Hey!
Your answer is 14m (2sf)
Step-by-step explanation:
<u>WE HAVE TO USE PYTHAGORAS!</u> ⇒ a²+b²=c² THEN √c = (unknown side)
Here: 12² + 8²= 208
Now SQUARE-ROOT 208! ⇒ √208
ANSWER: 14.42220510185596
The answers there are rounded up so we round this number to get 14m!
B IS YOUR OPTION!

Answer:
a. 7(2g + 20t –3)
b. 14g + 140t – 21
Step-by-step explanation:
a. The first expression 7(2g + 20t – 3)
Stacey and her six friends implies that we have 7 members in the group.
Therefore, the expression above implies that each member of the group has to pay for two rounds of golf and 20 tokens will be discounted $3.00.
The expression (2g + 20t –3) represents the quantity of cost of each friend and this is multiplied by 7 to obtain this first expression, i.e. 7(2g + 20t –3).
b. The second expression 14g + 140t – 21
The simple interpretation of this expression us that deducting $21 from the to total bill which is 14 games of golf plus 140 tokens is equal to the total amount this group spent.
Therefore, this second expression is obtained by simply opening the bracket in the first expression by multiplying 7 by each of the what is in the bracket.

c) Simon is ordering 5 cans and 5 racquets, the total from the cans is 5(4)=$20. Let x be the cost of each racquet,
Solving for x:
The actual distance would be 28mi
He would pay $14. Each juice bottle costs $2, so 7 bottles cost $14.
