Answer:
9/28
Step-by-step explanation:
First transform -2 1/3 to -7/3. Then find the reciprocal of -7/3 which is -3/7. Multiply that to 3/-4 which becomes -9/-28 which equals 9/28.
Answer: 4
Step-by-step explanation: 1/4w + 1/4w + w + w = 10
2/4w + 2w = 10
1/2w + 2w = 10
2.5w = 10
Divide 10 by 2.5
width = 4
Are you looking for the value of x?
We can complete the square/factor:
x^2+7x-30=0
(x+10)(x-3)=0
By the zero product property rule, we have two equations, x+10=0 and x-3=0.
So the zeroes of x are -10 and 3
Hope this helped. Comment below if this didn't make sense.
Answer:
See below.
Step-by-step explanation:
Draw segment OB.
In triangle OBC, points R and S are the midpoints of sides OC and BC, respectively. That makes RS parallel to OB.
In triangle OBA, points P and Q are the midpoints of sides OA and BA, respectively. That makes PQ parallel to OB.
Since segments RS and PQ are parallel to segment OB, then RS and PQ are parallel to each other.
