1 hour = 60 minutes
1 km = 1000 meters
55 x 1000 = 55,000 meters
55,000 / 60 minutes = 916 2/3 meters per minute
916 2/3 meters per minute x 12.5 minutes = 11,458 1/3 meters every 12 minutes and 30 seconds
4x + 5(3x+2) = 48
4x + 15x + 10 = 48
19x + 10 = 48
19x = 38
x = 2
y = 3x + 2
y = 3(2) + 2
y = 6 + 2
y = 8
Answer:[m, m+d, m+2d, - - - - -, n]
Step-by-step explanation:
We know the formula for arithmetic progression is a_(n) = a_(1) + (n-1)d
Where a_(n) is the nth term of the sequence
a_(1) is the first term of the sequence
n is the number of the term like if we are talking about 7th term so the n is 7.
d is the difference between two successive terms.
For this problem we know our first term that is m, our last term that is n and our difference that is d.
For second term we will use the formula
a_(2) = m + (2-1)d
a_(2) = m + (1)d
a_(2) = m + d
Similarly,
a_(3) = m + (3-1)d
a_(3) = m + (2)d
a_(3) = m + 2d
15^ is equivalent to 0.15, or 15/100. If you divide both numerator (15) and denominator (100) by 5, you get 3/20.
28% corresponds to 0.28. What fraction would that be?
Come on. Show your stuff.
1) Just simplify the equation first:
y - 9 = (2/5)(x - 5)
y - 9 = 2x/5 - 2
2) Transfer everything to the left with opposite sign:
-2x/5 + y - 9 + 2 = 0
-2x/5 + y - 7 = 0
3) Get rid of rational numbers by multiplying:
-2x/5 + y - 7 = 0 |*5
-2x + 5y - 35 = 0
That's the answer. Good luck!
