1) 2x + 8y = 20 what's the solution so confused y = 2

8 0

If y is equal to 2 then you can find x by putting 2 for y so you will have:
2x + 8(2) = 20
2x + 16 = 20
2x = 20 - 16
2x = 4
x = 4/2
x=2 :)))
i hope this is helpful

2x + 8y = 20
y = 2

Substitute y with its value.

2x + 8y = 20
2x + 8(2) = 20
2x + 16 = 20
2x = 20 - 16
2x = 4
x = 4/2
x = 2

x = 2; y = 2

2x + 8y = 20
2(2) + 8(2) = 20
4 + 16 = 20
20 = 20

What is value of x Plz help

KatRina [158]

Answer:

10√2

Step-by-step explanation:

This is a 45-45-90 triangle which means that the two non-hyptonouse lenghts are the same which means that the bottom lenght of the triangle is also 10 units

We can then use a^2+b^2=c^2 to solve for the last side

so we have

10^2+10^2=x^2

200=x^2

sqrt200=x

and I see that they want an exact answer so you simplify sqrt200 to

10√2
