225*(x+1/25)+225*(y-4/9)=225*1
9(x+1)+25(y-4)=225
9x+9+25y-100=225
9x-91+25y=225
9x=225+91-25y
9x=316-25y
x=316/9-25/9
Answer:
8
Step-by-step explanation:
The ratio is 3/2 boys/girls
if we call the expression as x there would be a total of 5x girls and boys
3x of this is boys
3x = 12 so x is 4 then 4×2 = 8 girls
Answer:
1232
Step-by-step explanation:
Answer: The height of tree = 15 ft. 6 inches
Step-by-step explanation:
Given: A person's height is 5-ft 3-in = [5 x (12 )+3 ] inches [ 1 ft= 12 inches]
= 63 inches
Their shadow has a length of 3-ft 6-in = [3 x 12+6] inches
= 42 inches
If a nearby tree has a shadow of length 10-ft 4-in = [10 x 12+4] inches
= 124 inches.
At the same time,
Hence, the height of tree = 15 ft. 6 inches
Interest = $500*0.12=$60
Processing fee = $25
Total finance charge = $(60+25)=$85.
APR=(total finance charge)/amount borrowed
=85/500
=17%
