Hey there!
When you have a number you are starting with that is your 100%. If he next number you have is higher it's going to be more than 100%, and if the other number is less it's going to be less than 100%. Since Tuesday's speed is twice as fast as Monday's, her speed increased by 100%
Hope this helped, have a good one :)
8x+6-9x= 2-x+4
8x+6+-9x=2+-x+4
(8x + -9x) + (6) = (-x) + (2+4) (combine like terms)
-x+6= -x+6
-x+6+x=-x+6+x
6-6=6-6
0=0
You answer to this question is
The answer is choice 4, they add up to 180°
Answer:
7.5
Step-by-step explanation:
So the constant proportionality is easy, it is the depindent veriable (how much it cost) divided by the independent veriable (how much fabric you have).
Put simply you know how much it will cost if you know how many yards you have. so if i have 2 yards i know it cost 15 dolars.
We could make a simple algebraic expretion that describes the proportionality.
C⁒y=7.5
So 7.5 is our constant, so if you know the cost or how many yards we have we always know what the other is.
So if i had 6.7 yards how much would it cost.
It would cost $50.25, what i did was i multiplied 6.7*7.5(our constant) and we got out cost c. Just to dubble check we can plug it in;
50.25⁒6.7 does=7.5 so it works.
