We have such equation
1.25x=0.75x+50 /-0.75x (subtract 0.75 both sides)
1.25x-0.75x=0.75x-0.75x+50
0.5x=50 /*2 (multiply both sides times 2)
0.5x*2=50*2
x=100 - its the answer
Answer:
x=7
Step-by-step explanation:
Information provided
Weight of ant=
Weight of lion=
but units are not provided, assuming this unit is also grams
How many times lion's weight exceed an ant

=
Therefore, the value of x=7 if the unit for weight of lion is assumed to be same as unit for weight of an ant

Answer:

Step-by-step explanation:
Let
x ----> the measure of one angle of the triangle
y ---> the measure of the second angle
z ----> the measure of the third angle
we know that
The sum of the measure of the interior angles in any triangle must be equal to 180 degrees
-----> equation A
One angle of a triangle measures 10 degrees more than the second
----> equation B
The measure of the third angle is twice the sum of the first two angles
---> equation C
substitute equation B in equation C

----> equation D
substitute equation D and equation B in equation A

solve for y

Find the value of x

Find the value of z

therefore

14^2 - 9^2 = a^2
Easy enough
14^2 = 196
9^2 = 81
196 - 81 = 115
The square root of 115 = 10.72
The third side is 10.72km
