Answer:

(0,-3)

Step-by-step explanation:

hi, with this we can just do substitution (substitute x for y+3)

6(y+3)-5y=15

evaluate

6y+18-5y=15

y+18=15

y=-3

then we plug that in

x=-3+3

x=0

jake can carry 6 1/4 pounds of wood in from the barn. His father can carry 1 5/7 times as much as Jake. How many pounds can Jake

Studentka2010 [4]

It would be: 6 1/4 * 1 5/7
= 25/4 * 12/7
= 300/28 = 150/14 = 75/7

In short, Your Answer would be 75/7 or 10 5/7 Pounds

Hope this helps!

OLga [1]

It depends how you name the sides of triangle.
Look at picture at the result.

$cos\alpha=\frac{12}{13}\\
cos\beta=\frac{5}{13}$

PS. Sorry for my terrible drawing but I did it as fast as possible :)
