Answer:
From 2.5 y to 1.5 y there is a 40 % DECREASE in the value.
Step-by-step explanation:
Here, the initial value = 2.5 y
The final value of 1.5 y
Now,as Final Value < Initial Value
So, there is a DECREASE IN THE VALUE.
Now, decrease in the value = Initial value - Final Value
= 2.5 y = 1.5 y = 1 y
or, there is a decrease of ( 1 y) in the given value.
Now, Percentage decrease in the value is given as:

or, Percentage Decrease = 40%
Hence, from 2.5y to 1.5y there is a 40 % DECREASE in the value.
Answer:
x = 5
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles in the triangle and equate to 180, that is
10x - 4 + 8x + 3 + 91 = 180
18x + 90 = 180 ( subtract 90 from both sides )
18x = 90 ( divide both sides by 18 )
x = 5
