Answer:
6+x with x equalling the amount of coins bought if that is what you were looking for
Step-by-step explanation:
if you want to make and equation out of this you don't know the amount of coins she bought so you use a variable (x) to replace that unknown number then since it says she bought more she is adding more to her collection which means it would be an addition problem, leaving you with 6+x for your final answer
Well, the first 16 were about 16*75=$1200 extra. The last 8 were $720 lost. Thus, the total profit is $480. He bought them with $7200, which means the profit is around 6.67%.
Answer:
Option C. 
Step-by-step explanation:
we know that
If two figures are similar, then the ratios of its corresponding sides is equal and its corresponding angles are congruent
so
m<A=m<J
m<B=m<K
m<C=m<L
therefore
The measure of angle J is the same that the measure of angle A

Answer: 6 and -1/6
Step-by-step explanation:
solving for y. You get y = -2x +5, so the slope is –2. Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6.
Answer:
46
Step-by-step explanation:
he count of numbers from 1 to n that are divisible by k is integer part of (n/k).
So the numbers from 1 to 99 divisible by 3 is int(99/3) = 33
Those divisible by 5: int(99/5) = 19
From the sum of those two, subtract those divisible by 15 = int(99/15) = 6
That gives you 33+19-6 = 46.
Now subtract the 1 digit numbers: 3, 5, 6, 9, or four of them
46 - 4 = 42 is the answer.
