Make this on form of a simultaneous equation:
assume jelly beans is J and trail mix is T
8J+4T=21
3J+2T=9
then solve
multiply the first equation by 3 and second equation by 8(SO THE J CAN DISAPPEAR[ELIMINATION METHOD])
24J+12T=63
24J+16T=72
Subtract
-4T=-9
T=0.44
then substitute the T to any one of the equation
3J+2(0.44)=9
3J+0.88=9
3J=8.12
J=2.71
therefore, jelly beans= $2.71 and trail mix=$0.44
The correct answer choice is b!
Answer:
Drew studied for an hour for 4 days in a row. How many hours did he study? Drew studies for 2.5 hours.
Step-by-step explanation:
The model shows that drew studied 2/8 every day and 2/8 is equal to 1/4 cut all five days that he studied in half and you get 2.5.
1. This answer would be C, n^3 + 5
2. This answer would be D, n^3 + 9
3. This answer would be A, 4n - 11
Answer:
306 km
Step-by-step explanation:
put both of them to equal in ratio form so now
85 / (7/6) = x / (21/5)
85 * (21/5) = 7/6x
357 = 7/6x
x = 306 km
