It's fairly easy.
634,721.00 would be the answer, if you rounded 634,721 to 2 decimal places.
Kelly's sister is x years old.
Kelly is 3 years younger than her sister, so Kelly is x - 3 years old.
The sum of their ages is x + x - 3 = 2x - 3.
The sum of their ages is 34, so
2x - 3 = 34
2x = 37
x = 18.5 Kelly's sister's age.
x - 3 = 18.5 - 3 = 15.5 Kelly's age.
Kelly's sister is 18.5 years old.
Kelly is 15.5 years old.
Answer: 33°
Step-by-step explanation:
The sum of the angles in a triangle is 180°. Since we are given 2 angles, we can solve for x.
180=90+57+x
180=147+x
x=33°
1) m - 7 < 6
Add 7 to the both sides,
m - 7 + 7 < 6 + 7
m < 13
So, Option C is your answer for this part.
2) x+4.5 ≥ 5.5
Subtract 4.5 from both sides,
x ≥ 1
So, Option B is your answer for this part.
3) p +12 > 9
Subtract 12 from the both sides,
p > -3
So, Option D is your answer for this part.
4) x - 5 ≥ 9
So, Option A is your answer for this part
Hope this helps!
