Answer:16
Step-by-step explanation:
Let the number be X
Twice the sum of a number and 5
= 2X+5
Three times the difference of the number and 2
= 3(X - 2)
Since Twice the sum of X and 5 is equal to three times the difference of the X and 2, This means
2(X + 5 )= 3(X - 2)
2X +10 = 3X - 6
3X -2X = 10 + 6 = 16
X = 16
Check
2×(16+5) =3×(16-2)
2×21 = 3×14
42 = 42
What I suggest is to round the numbers. 4 rounds up to 5. 275 would round up to 280 or 300 whatever is easier. your expression would be 5*280 or 5*300.
I hope this helped :)
Answer:
no yes no yes
Step-by-step explanation:
Im pretty sure thats correct
The Pythagorean theorem tells you
... (height of ladder)² + (distance from house)² = (length of ladder)²
... (height of ladder)² + (8 ft)² = (12 ft)²
... height of ladder = √(12² - 8²) ft
... height of ladder = √80 ft ≈ 8.94 ft
