Round 5.2654 to the nearest tenth.

The nearest tenth is the number that is one digit after the decimal. So when rounding 5.2654 to the nearest tenth, we will only have one number after the decimal point. The number currently at the tenth place is 2. Now let's look at the digit after 2. Is that digit bigger, equal or smaller than 5? The number is 6, which is bigger than 5. Since the digit after the tenth place is bigger than 5, the digit is the tenth place will go up a unit when rounding. Which means that 2 will become 2+1 = 3. Now, we can round the number 5.2654 to 5.3.

Solve 5x-7 = 3x+25

Let's start by substracting 3x from both sides, so as to have all x on the left side: 5x-7 -3x = 3x+25 -3x 2x-7 = 25 Now, let's add 7 to both sides so as to have all constansts on the right side of the equation: 2x-7+7 = 25+7 2x=32 Let's divide both sides by 2 to obtain what x is equal to: 2x/2 = 32/2 x=16
