i just think so correct me if im wrong
1. This problem lacks given values, where are the
numbers? Just fill-in the numbers I will variables in this case.
Let us say that:
x = number of cups of flour
y = number of cups of white sugar
z = number of cups of brown sugar
(a) Just divide x by 6 to get cups of flour per serving
x / 6
(b) Simply add y and z and divide the sum by 6
(y + z)/6
(c) From (a) we know that there are x / 6 flours per
serving, so simply multiply that by 9 then subtract the original x to know how
much more you need:
[(x / 6) * 9] – x
2.
(a) We know that we deposit $5 per day, so after 5 days
we got:
total deposit = ($5 / day) * 5 days = $25
(b) The total deposit is 25 dollars, so removing $2 a day
we need:
25 / 2 = 12.5 days
3.
(a) d is distance, R is rate, T is time
32.12 = 8.8 T
(b) It is rightful to write distance d as a positive
number since the scuba diver was ascending towards the surface. If this is to
be plotted on a Cartesian plane, we are moving towards the positive y axis
(c) solving for T:
32.12 = 8.8 T
T = 32.12 / 8.8
T = 3.65 minutes

Answer:
Step-by-step explanation:
you have to
first multiply the numbers you have in the column with the ones in the rows
8x* 5x = 40x² top left
8x* (-3) = -24x bottom left
-1 * 5x = -5x top right
-1* (-3) = 3 bottom right
second add and subtract all
40x²-24x-5x+3 = 40x²-29x+3
Answer:
A
Step-by-step explanation:
If you convert the equation you get
20/100=x/10
and convert the 20/100
so 2/10=x/10 so A or 2
