Answer: x=55
Step-by-step explanation: 35+35=70. 180-70=110. 110/2=55.
Answer:

Step-by-step explanation:
Let
D(t) = the distance to the safe zone (measured in meters)
t = time (measured in seconds)
<u>Given:</u>
Rachel's rate = 24 meters per second
At
seconds
meters
<u>Find:</u> D(t)
Rachel's rate is the slope of the function D(t). Since the distance is decreasing when the time is increasing, the slope must be negative.
Hence, the function expression is

To find b, substitute
and 

So,

If Sonya already has 140 beads, she needs 60 beads in order to have a total number of 200 beads. You have to find how many bags (that hold 10 beads) are needed to add up to 60.
140 + 10x = 200
10x = 60
x = 6
Sonya needs 6 bags
Answer:x=-1
Step-by-step explanation:
The spoke of the wheel serves as the radius of the circle.
To solve for the circumference of the circle, we use this formula:
C = 2πr
42 inches = 2 * 3.14 * r
42 inches = 6.28 * r
42 inches / 6.28 = r
6.69 inches = r
The length of each spoke is 6.69 inches.
