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:
x=8
z=132
Step-by-step explanation:
We know that 6x and 4x+16 are vertical angles, so they are equal
6x= 4x+16
Subtract 4x from each side
6x-4x = 4x-4x+16
2x =16
Divide each side by 2
2x/2 =16/2
x =8
We also know that 6x and x form a straight line
6x+z = 180
6(8) + z =180
48+z =180
Subtract 48 from each side
48-48 +z =180-48
z = 132
7 ∙ 15 can be written as 105
Distributive property
= 7(10 + 5)
the range would be the difference between the largest number and the smallest number.
smallest number = 12
largest number = 87
range is 87-12 =75
