C) 1/x + 1/y = x+y/x.y is the right answer. Why?
1- Morad will complete his task It's C) 1<span>/x + 1/y = x+y/xy. Why?
Morad complted his task in in "x" hours. and
</span>in 1 hour he will complete 1/x of the task
2- Elias completed his task in in "y" hours. and
in 1 hour he will complete 1/y of the task:
3- 1/x + 1/y = (x+y)/xy ( reduce to same denominator)
Answer:
(X1,y1)=(-5,-3)
(x2,y2)=(1,3)
Step-by-step explanation:
xsquared+5x-3-x=2
Perimeter = 2l + 2w
L=4+x
W= x
224 = 2(4+x) + 2x
224 = 8+2x+2x
216 = 4x
54 = x
Plugging x = 54 into initial dimensions:
L = 54 + 4 = 58
W = 54
Answer:
She gained 43 pounds each month.
Step-by-step explanation:
502 - 29 = 473 (because that was her weight at 0 months)
473 / 11 = 43.
I hope this helped
To solve, you divide 29.7 by 2.25 because you have a full rope of 29.7in and need 2.25in sections. This would leave you with 13.2 sections of rope. Hope this helped :)
