Answer:
when adding you just line the decimals up like this, let's say you had to add 1 to 2.58.
2.58
+ <u> 1 .00</u>
3.58
when multiplying you might have to move it, say you had to multiply 1.5 by 2.2. (you don't have to line up the decimals like with addition)
1 .5
<u> </u><u>×</u><u> 2.2</u>
30
<u> </u><u>+</u><u> 300</u>
3.30
1.5 has one decimal place and 2.2 also has one decimal place so you put those 2 decimal places in your answer.
sorry if this is a bit confusing lol
Answer:
x=27
Step-by-step explanation:
Triangles always add up to 180 so 90+63+x=180 (we know 90 is one of the degrees because of the triangles next to it) Now do some algebra: 90+63+x=180 add 90+63 together> 153+x=180 minus 153 from both sides it'll be x=27
distribute -9 to 2.7 and 1.55
-9x2.7= -24.3
-9x1.55= -13.95
then subtract -13.95 from -24.3
-24.3-(13.95)= -10.35
then add 3 to -10.35
answer= 7.35
8 1/3= 25/3
4 1/2= 9/4
25/3 / 9/4
= 25/3 * 4/9 use kcf (keep change flip)
=100/27
