Answer:
Noah is 17 and Tina is 7.
Why?
Let t represent Tina’s age.
So, 2t + 3 is Noah’s age.
This is your equation;
2t + 3 + t = 24
Now, simplify so t is on one side.
3t = 24 - 3
3t = 21
t = 21/3
t = 7
Tina’s age is 7, and Noah (according to the expression made for him) is 17.
Check:
7 + 17 = 24
Answer:
sorry not sure
Step-by-step explanation:
answer:
A) The angles EA and AG are not congruent.
B) m∠F = 90°
m∠E + m∠F = 180°
90 ° + x = 180° (subtract)
x = 90°
C) Both ∠HEF and ∠AGF are congruent becuase they both have the same angle. Try and measure it using a protractor.
Answer:
31
Step-by-step explanation:
although we cannot see the whole graph, I assume it would be 31 because
2010-1979 is 31
and the x values are years after 1979
