Solve 2x + 5y = –13. 3x – 4y = –8
2 answers:
If you would like to solve 2x + 5y = - 13 and 3x - 4y = -8, you can do this using the following steps: <span>2x + 5y = -13 /*4 3x - 4y = -8 /*5 </span>_________________ 8x + 20y = -52 15x - 20y = -40 _________________ 8x + 15x + 20y - 20y = -52 - 40 23x = -92 /23 x = -92 / 23 x = -4 <span>2x + 5y = -13 </span>2 * (-4) + 5y = -13 -8 + 5y = -13 5y = -13 + 8 5y = -5 y = -1 (x, y) = (-4, -1) The correct result would be D.) <span>(-4, -1).</span>
After solving the equations 2x +
5y = –13 and 3x – 4y = –8, I got the value (–4,
–1). The correct answer between all the choices given is the last
choice or letter D. I am hoping that this answer has satisfied your query and
it will be able to help you in your endeavor, and if you would like, feel free

1/5 is left.
Step-by-step explanation:
Portion remaining after the bar was eaten by his brother = 1 - 1/5 = 4/5.
Portion remaining after John ate 3/4 of this = 4/5 - 3/4* 4/5 = 4/5 - 3/5
= 1/5.
I’m pretty sure it’s 2 but i’m not 100 percent on that
To find the volume of a box-shaped fish trap, we have to multiply the three dimensions of it:
(1/4 m)* (2/3 m)* (3/5 m)
= (1*2*3)/ (4*3*5) m^(3)
= 6/ 60 m^(3)
= 1/10 m^(3)
= 0.1 m^(3)
The volume of the box-shaped fish trap is 0.1 m^(3).
Hope this is helpful~
