Solve 9/10=z/9 . round to the nearest tenth. 7.2 10.1 11.3 8.8

Remark

None of them are correct.

Solve

9/10 = z/9     Since 9 is smaller than 10 (both in the denominator), the answer(z) should be smaller than the nine in the numerator. That means that the second and third answers are incorrect. To find z, multiply both sides by 9

(9/10) * 9 = (z/9)*9

9/10 * 9 = z

9*9/10 = z

81/10 = z

z = 8.1

the last one is the closest, but there is no real answer.

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
