Answer:166
Step-by-step explanation:438x.38=166
438 being the total amount of students
.38 being the 38% involved (moved percentage two to the left to make it a decimal)
Answer:
to find the adverage you have to add the times together then divide them by 2 so 2 + 1.5 = 3.5/2= 1.75
Step-by-step explanation:
1. 35x + 0.15y
=3500x + 15y [multiplying the equation by 100]
= 700x + 3y [dividing the equation by 5]
2. Let x be an even integer
x + (x+2) + (x+2+2)
x+x+2+x+4
3x+6
3. 1/5*(r+7) - 9s
(r+7)/5 - 9s
4. x=cows
y= goats + sheep
x= (y+140)/2
The answer should be 6 units. -1 > 0 > 1 > 2 > 3 > 4 > 5 : 6 units
Answer:
Hence as long as x > 2/3, we can form a triangle from the three given sides.
Step-by-step explanation:
Given:
Length of 3 sides of triangle are 
Solution:
From the length of the 2nd side 4x, we know that x > 0
Let this be 1 st statement.
Now from the triangle inequality we can say that;

No new information from this because of the 1st statement above.
Also,

Lastly,

and again no new information is obtained from this inequality.
Hence as long as x > 2/3, we can form a triangle from the three given sides.
