Solve the linear inequality. <br> 5x-3(x+1)<7

Bond [772]

The solution to the inequality 5x-3(x+1)<7 is x<5.

Step-by-step explanation:

Given inequality is;

5x-3(x+1)<7

Solving the inequality

$5x-3x-3$

Adding 3 on both sides both sides of inequality

$5x-3x-3+3$

Dividing both sides of inequality by 2

$\frac{2x}{2}$

The solution to the inequality 5x-3(x+1)<7 is x<5.

Andrew and Elena knew that after 28 days they would have 2^28 coins, but they wanted to find out how many coins that actually is

kiruha [24]

Both Andrew and Elena are wrong. The actual value of 2^28 equals 268,435,456.

Step-by-step explanation:

Elena was right when she said exponents mean repeated multiplication but she accidentally calculated the value of 28^2 instead of 2^28. 2^28 means that the number 2 should be multiplied with itself for 28 times.

2^2 means 2 multiplied by 2 equals 4. 2^3 means 2 multiplied by 2 and then multiplied by 2 again which equals 8. Similarly, if you multiply 2 with itself 28 times you will get a value of 268,435,456 (two hundred and sixty-eight million, four hundred and thirty-five thousand, four hundred and fifty-six). So Andrew and Elena will have 268,435,456 coins after 28 days.
