Answer:
d. 3/2r+2c ≤ 10
Step-by-step explanation:
The amount of flour Molly needs for r batches of oatmeal raisin cookies is ...
3/2r
The amount of flour Molly needs for c batches of chocolate chip cookies is ...
2c
The total amount of flour Molly can use for cookies cannot exceed the amount available, so ...
3/2r + 2c ≤ 10

<em>Comment on the question</em>
The wording is a bit odd. It asks for the amount of flour available—after it tells you the amount available is 10 cups. (I might write that as <em>f ≤ 10</em>.) The answer choices clearly suggest that what is wanted is a representation of the possible mix of batches of cookies for which Molly could use the available flour. IMO, this is another instance of poor editing of math problem wording.
Answer:
see explanation
Step-by-step explanation:
Under a counterclockwise rotation about the origin of 270°
a point (x, y ) → (y, - x ) , thus
C)- 8, - 4 ) → C'(- 4, 8 )
D(0, - 4 ) → D'(- 4, 0 )
E(- 8, - 9 ) → E'(- 9, 8 )
It is D because us the given equation all you do is plug in the x values given on the chart
x*5 - quarter amount
(x+15)*25- nickels amount
(x*5)+((x+15)*25)=735
5x+25x+375=735
30x=735-375
30x=360
x=360/30=12 - number of nickels
x+15=12+15=27 - number of quarters
CHECK
12*5=60 ¢
27*25=675 ¢
675+60=735 ¢ or $7.35
Answer:
Step-by-step explanation:
- Initial point = -50 ft
- Climbing rate = 15 ft / min
- Time = t
<u>Required inequality:</u>
<u>Solution:</u>
- 15t > 55
- t > 55/15
- t > 3 10/15 = 3 40/60 min = 3 min 40 seconds
