Answer 1

15х10+(30-20)х5=200

15х10+30-20х5=80 

Answer 2

To solve the expression 15x10 + (30-20)x5, we need to follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).

Let's break down the expression step by step:

1. First, we need to simplify the expression inside the parentheses: (30-20). This equals 10.

2. Next, we multiply 15 by 10: 15x10 = 150.

3. Finally, we multiply 10 by 5: 10x5 = 50.

Now, we can substitute the simplified values back into the original expression:

15x10 + (30-20)x5 = 150 + 10x5 = 150 + 50 = 200.

Therefore, the solution to the expression 15x10 + (30-20)x5 is 200.
