In commutative property , we can add numbers in any order.
Here we are given with fractions
We can add or subtract fractions in any order
We change the order of fraction that has same denominator so that we can add it more easily using commutative property
The first two fractions have same negative sign and common denominator
so we add it
Simplify the fraction 12/ 16
Add the fractions
= -1
Maybe using scales because the apples and citrons have different weights.
BC = kBX
<span>CD = kXY </span>
<span>BC/BX = k = 10/6 </span>
<span>CD/XY = k = 10/6 = CD/4 </span>
<span>10/6 = CD/4 </span>
<span>CD = 40/6 = 6 2/3</span>
Answer:
<h3>p = 131.25</h3>
Step-by-step explanation:
The variation p varies directly with T is written as
p = kT
where k is the constant of proportionality
To find p when T =500 we must first find the formula for the variation
That's
when p = 105 and T = 400
105 = 400k
Divide both sides by 400
<h3>
</h3>
So the formula for the variation is
<h2>
</h2>
when
T = 500
Substitute it into the above formula
That's
Simplify
The final answer is
<h3>p = 131.25</h3>
