I think the answer is substitution property of equality because you are substituting 9 for y as y=9.
Let the amount saved by the brother that has less savings be x, then the savings of the other brother is x + 15.
Since their total savings is 55, then
x + x + 15 = 55
2x + 15 = 55
2x = 55 - 15 = 40
x = 40 / 2 = 20
Therefore, one person saved 20 and the other saved 20 + 15 = 35.
2 + 3w < -1 < 3w + 5 |subtract 3w from all sides
2 < -1 - 3w < 5 |add 1 to all sides
3 < -3w < 6 |change the signs
-3 > 3w > -6 |divide both sides by 3
-1 > w > -2 → -2 < w < -1 → w ∈ (-2, -1)
Area of the figure = Area of rectangle + area of semi-circle
Area of rectangle = a * b = 6 * 2 = 12 m²
Area of the semi-circle = πr²/2 = 3.14 * (1.5)²/2
A = 3.53
Area of figure = 12 + 3.53 = 15.53 m²
In short, Your Final Answer would be: 15.53 m²
Hope this helps!
Answer:
pretty sure its 1/12
Step-by-step explanation:
on two six sided dices I know that the probability of ten is 3/36. When you simplify that you get 1/12
