Um do you ave any answer choices ? i would say <span>Pythagorean theorem.
thats my best guess </span>
For the answer to the question above,
<span>10x^2-36y^2=100
Then isolate x^2, first add 36y^2 to both sides: 10x^2 = 100 + 36y^2 divide both sides by 10:
x^2 = 10 + 3.6y^2 or
10 + 36/10 * y^2 = 10 + 18/5 * y^2
</span>
So the answer to this question is
<span><span>x2</span>=10 + (<span>18/5)</span><span>y2
I hope my answer helped you. Have a nice day!</span></span>
3 x 50 = 150
150 x 1.25 = 187.5
If you were to buy just brats, you would spend $187.50. So, you would have a spare $12.50, which could buy you 8 more.
3 x 50 = 150
150 x 0.95 = 142.5
If you were to buy just hamburgers, you would spend $142.50. So, you would have a spare $57.50, which could buy you 60 more.
Answer:
27 + (-40) = -13
Step-by-step explanation:
27 + (-40)
= 27 - 40
= -13
10 - 2x = -30
-2x = -40
2x = 40
x = 20
