Answer:
5x + 6y = 20_____(1)
8x - 6y = -46_____(2)
Solving simultaneously:
Eqn(1) + Eqn(2)
5x + 8x + 6y + (-6y) = 20 + (-46)
13x = -26
x = -2
substituting this into Eqn (1):
5(-2) + 6y = 20
-10 + 6y = 20
6y = 30
y = 5
hence:
x = -2,y = 5.
3/5 miles = 0.6 miles
0.6/4= 0.15 miles
Nikki walked 0.15 miles or 3/20 miles.
Multiply the bottom of the fractions together (4*5=20) and the tops (3*1=3) to get 3/20.
Answer:
2
Step-by-step explanation:
Divide by 4 on each side.
4x/4 and 8/4
Now we have just x on one side and 2 on the other.
So, x = 2.
Answer:
74
Step-by-step explanation:
Both angles x and 106 are supplementary which means
x+106=180
x=180-106
x=74
