Answer:
Step-by-step explanation:
In a parallelogram, this one in particular:
KR = RM
JR = RL
We are looking in the end for the length of JR, but that means that we need to solve for x somehow to plug in the expression for JL, and then split that in half. Here's how we're going to go about it. I know that
KM = KR + RM, but since KR and RM are the same length, the equation becomes
KM = 2KR. Filling that in with the expressions I'm given for KM and KR:
3x - 5 = 2(x + 7) and
3x - 5 = 2x + 14 and
x = 19. Now I can find the length of JL:
JL = 4x - 10 so
JL = 4(19) - 10 and
JL = 66
Knowing that JR = RL and JL is 66 units long, JR = RL = 33 units each.
Answer:
44 degrees and 46 degrees.
Step-by-step explanation:
If one angle is x degrees then its complementary angle is 90 - x degrees.
x is 2 degrees less than (90 - x) degrees so:-
(90 - x) - x = 2
90 -2x = 2
2x = 88
x = 44
the other angle = 90 - 44 = 46 degrees.
Answer:
2 1/2 hours
Step-by-step explanation:
1. multiply 12 by 2 to get 24
2. divide 12 by 2 to get 6 mph (miles per hour)
3. Add the 6 and 24
<span>Abdul used a probability simulator to roll a 6-sided number cube and flip a coin 100 times. The results are shown in the tables below:

Using Abdul's simulation, what is the probability of rolling a 2 on the number cube and the coin landing heads up?
Yes I think it is correct
