7. the unit rate is 30 divide 60 by 2 and 90 by 3 to show u r work
8.the unit rate is 1.89 divide 18.90 by 10 and so on
Answer:
8cm
Step-by-step explanation:
Since the area of a square is Side X Side (s x s) it is also s². The s² is also equivalent = 64cm². To find the length of a side you do the √64cm² and you get 8cm for a side. Great Job!
I'm not really sure, because 650 marked down by 27% would be 474.5, which is close but not exact.
Hope I helped a little bit, sorry if I'm wrong.
First, you want all the variables to be on one side:
a - 3b = 4
a - b = -2
Now you want to eliminate one of the variables, in this case a is easiest.
Subtract the second equation from the first and you're left with:
-2b = 6
so b = -3
Sub the value of b back into either of the equations and solve for x:
a - (-3) = -2
a = -5
So your answer is (-5,-3)
Answer:
A
Step-by-step explanation:
For a function, the input only has one output. For example, if we take gender as our input and age as our output. There can be more than one female or male with different ages.
A function does not have to be a quantitative number, as long as it follows the one output for every input rule.
