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

What is the answer to 11x+4+51+2x+8=180
Digiron [165]
Hi,

Work:

Equation;

11x + 4 + 51 + 2x + 8 = 180

Collect like terms and calculate sum of positive numbers.

13x + 63 = 180

Move constant +63 to the right side and change its sign.

13x = 180 - 63

Subtract numbers.

13x = 117

Divide both sides of equation with 13.

x = 9


Hope this helps.
