Answer:
x = 64
Step-by-step explanation:
they give you two angles 56 and 60
add them and subtract from 180
180 - 116 = 64
Let x be the time she ran and y be the time she walked
then distance ran = 25x and distance walked = 5y
so 15x + 5y = 42
and x + y = 4
* second equn. by -5:-
-5x - 5y = -20
add this to the first equn:0
10x = 22
x = 2.2
distance she ran = 2.2 * 15 = 33 km
Answer:
19683
Step-by-step explanation:
1. find the ratio
this is geometric so..
54÷18=3
18÷6=3
2. set up the problem
3(3)^9-1
3^8= 6561
6561(3)=19683
