i multiplied each number and the answers that i got i added them to get the area
12
13
78
97
65
90
70
these are numbers with 2 digits
first subtract the last equation from the first. this gives:-
-x + y = -8 .....................(1)
Then multiply the first equation by 2 and add it to the 2nd equations This gives
9x = 18
so x = 2
and from equation (1) y = -8 + 2 = -6
Substituting for x and y in the second equation
z = (24 -5(2) -12) / 2 = 1
Answer is choice b.
46200000000.
12000000000.
you just move the decimal 10 places to the right
True
This is because on replacing for x=5;
y=2x-11
y=2(5)-11
y=10-11
y=-1
