Answer 2

Let's solve the equation and the expression step-by-step:

1. Equation: 1500:х = 700 * 2 To solve for x, we need to isolate it on one side of the equation. We can do that by dividing both sides of the equation by 1500:

1500:х = 700 * 2 х = (700 * 2) / 1500 х = 1400 / 1500 х = 0.9333...

So, the solution for the equation is approximately x = 0.9333... (repeating decimal).

2. Expression: 930 * 86 + 3468:34 Let's perform the operations in the correct order:

Step 1: Perform the division 3468:34 3468 divided by 34 is equal to 102.

Step 2: Perform the multiplication 930 * 86 930 multiplied by 86 is equal to 79,980.

Now, add the results of the two steps together:

79,980 + 102 = 80,082

So, the value of the expression 930 * 86 + 3468:34 is 80,082.
