2x - 3 = 8
add 3 to both sides
2x = 11
divide both sides by 2
x = 5.5
Answer: dang I learned this and forgot

Answer:
Step-by-step explanation:
A)
Dilation. Since it's only the size of the figure that's changing
B)
Height of the smaller one: 4
Width of the smaller one: 6
Height of the bigger one: 6
Width of the bigger one: 9
6/4 = 1.5
9/6 = 1.5
Since both 6/4 and 9/6 was 1.5, that means that the Width and Height was proportional and that the two trapezoids is at a ratio o:
1 : 1.5
One unit of the smaller one is 1.5 units on the bigger one.
Answer:
The diver’s depth is 18.5 feet below from sea level.
Given that, A diver begins at sea level and dives down 200 feet.
He ascends at a steady rate of 121/3 feet per minute for 4.5 minutes.
This depth is represented by the numerical expression is,
Negative sign indicate that below the sea level.
Hence, The diver’s depth is 18.5 feet below from sea level.
