You would want to subtract 18 from 45. Your answer would be y=27.
Answer:
The answer to your question is the height of the lamp is 18.2 ft
Step-by-step explanation:
Data
Street lamp shadow = 31.5 ft
Street sign height = 8 ft
Street sign shadow = 14 ft
Street lamp height = x
Process
1.- To find the height of the lamp use proportions. In this kind of problem, we do not look for the length, but the shadow.
Street lamp height/street lamp shadow = street sign height/street sign
shadow
Substitution
x / 31.5 = 8 / 14
Solve for x
x = (31.5)(8) / 14
Simplification
x = 254.4 / 14
Result
x = 18.2 ft
Answer: Elisa
Step-by-step explanation:
Since Elisa withdrew $23 at a time from her bank account and withdrew a total of $207, the number of times that Elisa withdrew will be:
= $207/$23
= 9 times
Since Frances withdrew $43 at a time from his bank account and withdrew a total of $172, the number of times that Frances withdrew will be:
= $172/$43
= 4 times.
Based on the calculations, we can see that Elisa made the greater number of withdrawal.
Answer:
The solution to this equation could not be determined! (O>O)
Step-by-step explanation:
Simplifying
4x2 + 6x + 12 = 0
Reorder the terms:
12 + 6x + 4x2 = 0
Solving
12 + 6x + 4x2 = 0
Solving for variable 'x'.
Factor out the Greatest Common Factor (GCF), '2'.
2(6 + 3x + 2x2) = 0
Ignore the factor 2, I think this is a 'trick' question !
