Answer:
y = 10
Step-by-step explanation:
Given y varies inversely as x then the equation relating them is
y =
← k is the constant of variation
To find k use the condition x = 4 when y = 15 , then
15 =
( multiply both sides by 4 )
60 = k
y =
← equation of variation
When x = 6 , then
y =
= 10

Answer: x = 25</h3>
=======================================================
Explanation:
Add up the parallel sides, and divide by 2
x = (15+35)/2
x = (50)/2
x = 25
The midsegment is the average of the two parallel sides.
Answer:
the angle are 50, 47, 83
Step-by-step explanation:
we know that the sum of the three angles of the triangle is 180 degree
now, 4x+22+3x+26+9x+20=180
x=7
the angle are 50, 47, 83
Answer:
The solution is that there are 26 students in her class
Step-by-step explanation:
We know that 15 of her student are girls, and since there are more girls than boys in the class, there can at most be 15+14= 29 students in her class.
We need to find a number x between 16 (in the case where there is only one boy in the class) and 29, for which x/4 gives a remainder of 2, and x/5 gives a remainder of 1.
The numbers between 16 and 29, which when divided by 4 gives a remainder of 2 are:
18, 22, and 26
You can check yourself that these give a remainder of 2.
So it is one of these numbers. But the solution must also fulfill that the number divided by 5 gives a remainder of 1.
18/5 = 15 + remainder=3
22/5 = 4 + remainder=2
26/5 = 5 + remainder=1
Thus the only possible solution is 26.
