3/10, 30%, 0.3
because 3/10 basically means 3 out of 10. that's 30%. 0.3 is just 3/10 in decimal form.
Answer:
A
Step-by-step explanation:
Given :
2x + 4y = 14 ---------- eq 1
4x + y = 20 ---------- eq 2
if you multiply eq 2 by -4 on both sides, you get
-4 (4x + y = 20) = -4 (20)
-16x -4y = -80 --------- eq3
we can see that eq. 1 and eq 2 together forms the system of equations presented in option A, Hence A is equvalent to the orginal system of equations given in the question.
Answer:
x = -2
x+3y = 4
This is the substitution method. You need to plug the -2 in x's place to get y.
-2+ 3y = 4
3y = 4+2
3y = 6
y= 6/3
y= 2
Y + 10 is how it would be written
