Your question states...
Sixteen -------> 16
divided by -------> /
the sum of x and 5 -----> x+5
is 12 ------> = 12
16/x+5 = 12
Answer D
The reason it is NOT answer A is because is says "divided by the sum of x and 5". In the order of operations, division happens before addition, so if it did not say "the sum of", then 16 divided by x (16/x) would happen before adding 5 (like in answer A). But is says "the sum of" so you have to do the addition first.
using pythagorean theorem
a^2 + b^2 = c^2
(12x)^2 + (16x)^2 = 10^2
square each term
144x^2 + 256x^2 = 100
combine like terms
400 x^2 = 100
divide by 400 on each side
x^2 = 1/4
take the square root on each side
x = 1/2
Answer: x=1/2
Answer:
try to be clear enough so that the answerer can understand
Step-by-step explanation:
.
There are two solutions
AG =BG
mesDBG = mesEBG
2/3 = 0.666
7/6 = 1.166
1/8 = 0.125
9/10 = 0.9
from least to greatest : 1/8 , 2/3 , 9/10, 7/6
