The given problem is "In an isosceles triangle, the uneven side is 8 cm shorter than each of the equal sides. Calculate the sides of the triangle knowing that the perimeter is 31 cm.
To find,
The sides of the triangle.
Solution,
Let each of equal sides are x.
The unequal sides is x-8.
Perimeter is the sum of all the sides. So,
31 = x+x+x-8
31+8=3x
3x = 39
x = 13
So, the equal sides are 13 cm.
Unequal side = x-8
= 13-8
= 5 cm
Hence, two of the equal sides are 13 cm and unequal side is 5 cm.
Answer: 8/10
Step-by-step explanation: so you have to multiply 5 times x u till you get 10 so you’ll multiply it 2 times and since you multiplied the left 5 times two you have to multiply the 4 by 2 also to keep everything equal so the final answer is 8/10
<span>1.333333333333333.... = 4/3.
To find this:
x = 1.3333333333333...
Multiply by 10:
10x = 13.3333333333...
Subtract x = 1.3333333333333333....:
9x = 12.
Divide by 9:
x = 12/9 = 4/3.</span>
.75 and 4 are the numbers you get when you divide the numbers
Answer:
The answer is 4 liters.
Step-by-step explanation:
We want a final 25% solution, which means that the solvent should constitute 25 percent of all the liters of solution.
Let us call 
the litres of 40% solution, so when they are added to the 12 litres of 20% solution, the total litres of the new solution are:
of these liters, 25% must be the solvent:
Now for the 40% solution, the liters of the solvent are 
, and for the 20% liter solution, the liters of solve are 
liters. Thus the total liters 
of the solvent are
Therefore
