Answer:
x=9
Step-by-step explanation:
FE is 3x-7
since ΔABC≅ΔDEF the equivalent of FE is CB, or BC...which is 20
3x-7=20
3x=27
x=9
oh, sorry my answer is wrong :) you can follow the other comment.
I would believe that the answer is 20,00 because i like to use the saying 5 or above give it a shove, for or less let it rest. So you use this saying for the number behind the number it says to round to. Which in this case is 4 so because according to the saying it says let it rest if the number is 4 or less. So that is how i got my answer :D Hope you understand now!!!
(-2,6)
for example
x+1/2y=1
the ordered pair i will use is the first one. (-2, 6)
so
(-2) + 1/2(6)=1
from there it is a simple add/subtract and multiply/divide math problem.
1/2(6)=3
so
(-2) + 3 = 1
yes this ordered pair works for the solution meaning it is the answer.
Answer:
x = y/3 plus 1/3
Step-by-step explanation:
isolate the variable by dividing each side by factors that dont contain the variable.
