Answer:
Yes, they are equivalent, and the second question is B
Step-by-step explanation:
If you add x on both sides of equation A, then it comes up to 5x+2=6, which is equivalent to equation B. For the second question, you are just basically adding a variable to each side, so it is B.
6x2.40=14.4
4.30x3=12.9
add.
12.90
14.40
=27.30
Hello!
Just multiply across:
4/5 * 20.5/1 = 4(20.5) / 5(1) = 82 / 5 = 16.4
So 4/5 of 20.5 is 16.4.
Hope this helps :))
Step-by-step explanation:
suppose,x=1,2 .so y=1+4=5,2+4=6...eq..(I)
and y=2×1-8=-6,y=2*×2-8=-4
now plot in graph where they intercept with each other i.e x and y
I could plot but it's difficult here..and remember u can suppose any point as x for y
