Answer:

18

Step-by-step explanation:

To solve we fist need to figure out what 40% is in decimal form. To do this we have to move the decimal point to the left 2 spaces.

40% -> 0.40

Then we can multiply...

45 · 0.40 = 18  (This means that 40% of the total 45 students is 18).

What is 3 tenths more than 8.154 ? What is 2 and 2 tenths more than 1.425? Explain please !
Anna11 [10]
8.454 is 3 tenths more than 8.154
3.625 is 2 and 2 tenths more than 1.425

Place values after the decimal point are tenths, hundredths, thousandths, ten thousandths...so on.

So 3 tenths looks like this 0.30 ⇒ 3 is in the tenths place. When you say 3 tenths more, it is a clue that the operation to be done is addition. thus,

   8.154
<u>+ 0.30
</u>   8.454   * in addition or subtraction, the decimal points must be aligned to avoid confusion. 

2 and 2 tenths is like this 2.20 ⇒ 1st 2 is in the ones or units place and the 2nd 2 is in the tenths place. Again it states more than so addition must be done.
 
   1.425
<u>+ 2.20</u>
   3.625

Vinil7 [7]

Answer:

c. x=3

Step-by-step explanation:

Given:

7x < 21

Divide both sides by 7

7x / 7 < 21 / 7

x < 21/7

x < 3

x = 3

Check:

7x < 21

7(3) < 21

21 = 21
