Answer:
a) 1/12
b) 3/4
c) 2/35
d) 20
e) 3/10
Step-by-step explanation:
a) 8x=2/3
x=(2/3)/8=1/12
b) 3/2=2x
x=(3/2)/2=3/4
c) 5x=2/7
x=(2/7)/5=2/35
d)1/4x=5
x=5/(1/4)=20
e)1/5=2/3x
x=(1/5)/(2/3)=3/10
Answer: b)1
Step-by-step explanation:
Answer: No.
Step-by-step explanation: This is not a right triangle because if you add up all the sides, it does not equal 90 degrees.
It would take 7:30 minutes to clear the rest of the 10 miles.
Same side angles together form angle with measure 180^{0}. Let x be a measure of smaller angle, then x+20^{0} is measure of bigger angle.
x+x+20^{0}=180^{0}
2x=160^{0}
x=80^{0}.
So measure of smaller angle is 80^{0} and measure of bigger angle is x+20^{0}=80^{0}+20^{0}=100^{0}.
