Answer:
2x+9=12x-21
-2. -2
9=10x -21
+21 +21
30=10x
Divide by 10 on both sides
30/10
x=3
Step-by-step explanation:
Answer:
Neither.
Step-by-step explanation:
you are correct about the pattern, so it's not adding the same number and not multiplying by the same number. So it's neither.
Answer:
37.8metres
Step-by-step explanation:
The arc of the arrow can be modeled by the equation:
y=-0.02x²+0.65x+4
Where x is the horizontal distance (in meters) from Linda and y is the height (in meters) of the arrow.
The arrow hits the ground when its height (y) is zero.
Therefore, we determine the value(s) of x for which:
y=-0.02x²+0.65x+4=0
Using a calculator to solve the quadratic equation:
x=37.79 or -5.29
Since the distance cannot be a negative value, we ignore -5.29.
The distance from Linda when the arrow hits the ground is 37.8metres (to the nearest tenth)
Answer:
1/18 or 0.0555... or %5.555...
Step-by-step explanation:
<u>Step 1: Find the probability of choosing a 1</u>
1 out of 6 → 1/6
<u>Step 2: Find the probability of choosing a blue chip.</u>
2 out of 6 → 2/6 → 1/3
<u>Step 3: Multiply it</u>
1/6 * 1/3
1/18
Answer: 1/18 or 0.0555... or %5.555...
21-4 is 17. you now have 17 apples
