Answer:
From the above we can roughly for an equation which is:
58.50 = Bill - (10% x Bill)
58.5 = Bill - (1/10 x Bill)
58.5 = 9/10 x Bill (Divide both sides by 9/10)
We get:
Bill = 58.5 / (9/10)
Bill = 65
Original bill is $65.
Answer:
160 meters
Step-by-step explanation:
Let call dj distance run by Jess and dw distance run by Wes
By Jess courtesy Wes will be 60 meters ahead of Jess
Let call t the time in which both runners are at the same point, which in fact is when both distances are equal
dj = 8 m/sec * t and dw = 60 + 5 m/sec * t
Then we make dj = dw
8*t = 60 + 5*t
3*t = 60
t = 20 sec
Now passed 20 sec dj = 8 * 20 = 160 m
and dw = 60 + 5*20 dw = 160 m
Answer:
XZ
Step-by-step explanation:
Line segments are straight lines, not curves.
The only line is XZ, the rest are arcs
Answer:
m = $6.5
s = $3
Step-by-step explanation:
Raul ordered 1 small photo enlargement and 4 medium photo enlargements for $29. Patricia ordered 5 small photo enlargements and 2 medium photo enlargments for $28. determine the price of the small photo enlargements and medium photo enlargments
two equations can be derived from the question
s + 4m = 29 equation 1
5s + 2m = 28 equation 2
where
s = small photo enlargements
m = medium photo enlargements
multiply equation 1 by 5
5s + 20m = 145 equation 3
subtract equation 2 from 3
18m = 117
m = 6.5
substitute for m in equation 1
s = 29 - (4 x 6.5)
s = 3
The two triangles are similar. The proportion of the two sides therefore are the same. So 6:5 is the same as 20:6+x. You can calculate the 6+x side based on this and the last step is to simply subtract 6 from the side.
