On Tuesday Pranav bought ten posters. On Wednesday half of all the posters that
he had were destroyed. On Thursday
there were only 23 left. How many did he
have on Monday?

Pranav had 36 posters on Monday.

Step-by-step explanation:

We can make up an equation to demonstrate this problem.

We don't know how many posters he had on Monday, so we can represent that amount as x. We know Pranav buys 10 more, so now it's x + 10. We also know that after he bought 10 more posters, half of all his posters got destroyed, leaving him with 23.

The final equation is:

(x + 10) ÷ 2 =23

We now need to isolate the x, so we multiply both sides by 2 to get rid of it.

It now equals:

x + 10 =46

Finally we subtract 10 from both sides.

Our answer is:

x =36

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5

i believe it is 0.1m because the measurement of 30.4m limits how precise you can be

you can only be as precise as the least precise measurement
