Answer:
I think that it equals 1ab. Because 3ab - 9ab= -6ab + 7ab= 1ab
Answer: it's 31.5
Step-by-step explanation:because you would times 9 by 21 then divide by 6
9*21=189
189/6=31.5
430,825 because if you add them up you get this
Y-12=-10, add 12 to both sides, the answer is y=2
I am going to assume these are points across the same line. (line segments)
If so, then jk + kl = jl
If jk is 6x and kl is 3x, we can solve for x.
6x + 3x = 27 (note we subbed 27 in for jl)
9x = 27 (divide both sides by 9 to leave on x on the left)
x = 3
CHECK! sub 3 in for x in the original problem.
6 (3) + 3 (3) = 27
18 + 9 = 27
Yes! It checks. x = 3
