Answer:
R = 90
Step-by-step explanation:
Triangles will always equal 180 degrees. If you add 61 + 29 = 90. If two of the three angles already equal 90 degrees, then you would subtract 180 - 90. Therefore, the remaining angle would have to be 90 degrees.
Answer:
Yes
Step-by-step explanation:
Answer:
x=2y-8
We use the substitution of x in the second equation
2*(2y-8)+3y= -2
4y-16+3y=-2
7y-16= -2
7y= -2 +16
7y=14
y=14Ș7
y=2
so x= 2*2 -8
x=4-8
x=-4
the solution is (x,y)=(-4, 2)
Step-by-step explanation:
Find all solutions for w by breaking the absolute value into the positive and negative components.
w = 7, -1

Answer:
160 meters
Step-by-step explanation:
Let call dj distance run by Jess and dw distance run by Wes
By Jess courtesy Wes will be 60 meters ahead of Jess
Let call t the time in which both runners are at the same point, which in fact is when both distances are equal
dj = 8 m/sec * t and dw = 60 + 5 m/sec * t
Then we make dj = dw
8*t = 60 + 5*t
3*t = 60
t = 20 sec
Now passed 20 sec dj = 8 * 20 = 160 m
and dw = 60 + 5*20 dw = 160 m
