Answer:
D.
Step-by-step explanation:
If you would rotate RN until R meets L it would exactly overlap with FL. So RN=FL.
its b

Answer:
Todd has 540540 songs in his playlist.
Vlad has 270270 songs in his playlist.
Becca has 162162 songs in her playlist.
Step-by-step explanation:
# of songs Todd has = T
# of songs Vlad has = V
# of songs Becca has = B
1) Todd has twice as many songs in his playlist as Vlad:
T=2V
2) Becca has three times as many songs in her playlist as Todd:
B=3T
3) All three people have a total of 243243 songs in their playlists:
T+V+B=243243
Because T=2V then you can substitute T as 2V in the second equation:
B=3(2V)
B=6V
Now in the final equation, you can substitute everything for V:
2V+V+6V=243243
9V=243243
V=27027
Now substitute for T:
T+1/2T+3T=243243
9/2T=243243
T=54054
Now substitute for B:
1/3B+1/6B+B=243243
3/2B=243243
B=162162
Check answers:
27027+54054+162162=243243
243243=243243
Answer:
43 questions in total
Step-by-step explanation:
the original equation with the unknown (total number of questions on the test) will look like this
we know this because to work out a percentage in the 1st place you need the total ÷ number (in this case it's ÷ how many questions out of the total she did answer)
now you rearrange.
you need to move the 24 to get the total on it's own here's how you do it
what you do to one side of equation you have to do to the other. the 24 and 24 on the left will cancel because 24÷24=1 and we don't write
got mum of Q's x 1= 80 x 24
now you convert % to decimal
replace
now you take the original and + the 19
therefore there are a total of 43 questions on the exam
Answer:
Step-by-step explanation:
The slope intercept form equation of a straight line is expressed as
y = mx + c
Where
m represents slope
c represents y intercept.
Comparing the given equations with the slope intercept form equation,
2) y = 4x + 14 is in the slope intercept form. Its slope is 4 and the intercept is 14.
3) y = -4x + 14 is in the slope intercept form. Its slope is - 4 and the intercept is 14.
4) y = 2x + 7 is in the slope intercept form. Its slope is 2 and the intercept is 7.
5) y = -2x + 7 is in the slope intercept form. Its slope is - 2 and the intercept is 7.
