Answer:
n = 10
Step-by-step explanation:
given m varies directly as n then the equation relating them is
m = kn ← k is the constant of variation
to find k use the condition m = 6 when n = 5
6 = 5k ( divide both sides by 5 )
k = = 1.2
m = 1.2n ← equation of variation
when m = 12 , then
12 = 1.2n ( divide both sides by 1.2 )
10 = n
Answer:
x = 23
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
=
=
= 3
multiply both sides by (x - 10)
3(x - 10) = 39 ( divide both sides by 3 )
x - 10 = 13 ( add 10 to both sides )
x = 23
Answer: The expression representing the amount of money spent is by Emily.
Step-by-step explanation:
Since we have given that
Let the cost price of per pair of sandals be 's'
Let the cost price of per pair of boots be 's+30'.
Number of pairs of boots = 2
Number of pairs of sandals = 3
Total cost would be
Hence, the expression representing the amount of money spent is by Emily.
