We can solve this by writing down all of the variables we know. We will call the distance traveled on Saturday, x. The distance traveled on Sunday will be y.
x = distance traveled saturday
y = distance traveled sunday
We are told that on sunday he rode 3 miles more than 2/3 the distance on saturday. We can write a new formula.
y = (2/3)x + 3
We also not the total distance travelled, x + y = 43, now we solve for x.
x + y = 43
x + (2/3)x + 3 = 43
5/3x = 40
x = 24 miles
y = (2/3)(24)+3
y = 19 miles
Therefore, Mario biked 24 miles on Saturday and 19 miles on Sunday which gives us the total of 43 miles for the whole weekend.
14. B (4, -2)
15. I am not exactly sure about this one but I would say either A or B.
The Rusty Pelican Miami Restaurant will host Seafood Scotland's dinner promoting salmon and other seafood exports. Click on image to enlarge.
1.25s+y=t
a= fair admission
1.25s=amount spent on tickets for rides
t=total
Example
1.25*25+y=t
31.25+y=43.75
y=12.50
If you multiply the price of the ride tickets by the amount bought then subtract it from the amount spent total you get the admission price. You can use this equation for anyone who only pays for the rides and fair admission
X = 60°
Hope this helps ;)
