Write x-4 instead of y.
x²+(x-4)²=40
x²+x²-8x+16=40
2x²-8x-24=0
x²-4x-12=0
(x-6)(x+2)=0
x=6 or x=-2
for x=6, y=6-4 = 2
for x=-2, y=-2-4 = -6
(8.6 x 108) x (3.2 x103
place them in order
(8.6 x 3.2) x (108 x 103)
27.52 x (108 x 103)
27.52 x 11124
That is your answer to this question.
Answer:We have, 38% × x = 190
or,
38
100
× x = 190
Multiplying both sides by 100 and dividing both sides by 38,
we have x = 190 ×
100
38
x = 500
If you are using a calculator, simply enter 190×100÷38, which will give you the answer.
