Answer:

At least 6 strikes
Step-by-step explanation:
The required numerical data is missing from the question. In the original question, Roni gets a strike 2 out of 10 times and her goal is to have a minimum strike rate of 50%. The number of consecutive strikes required is given by the following inequality:

Solving the inequality:

Roni needs at least 6 strikes.

Answer:
3x^2 (5y^2 - xy + 25x^2)
Step-by-step explanation:
Answer:
-2
Step-by-step explanation:
We have to multiply 10 and 
Here we have to distribute the negative sign.
Distributive property = -(a) = -a
Using the above property, we get
= 
Now we have to multiply 10 and 
= 10 × 
= 
= 
Now we have to divide -10 by 5.
= -2
Answer: x=7
ab=21
bc=14
Step-by-step explanation:
ab=3x
bc=2x±7
ac=42
3x±2x±7=42
5x±7=42
5x=42-7
5x=35
to get the value of x you divide 35 by 5x
35÷5x=7
so the value of x is 7
ab=3x
x=7
3x=7×3x
7×3=21
x=7
2x=7×2x
2×7=14
