Answer
<em>For number 29 the answer is </em><em>9.</em>
<em>30 is</em><em> 53.</em>
<em>31. is </em><em>28.</em>
Step-by-step explanation:
29. 2 : 3
6 : x
<em>So, 3 times 6 equeals to 18.</em>
<u><em>18 divided by 2 is 9, so x equals to 9. </em></u>
30. 3 (1 2 - 5) + 8 × 4
12-5 =7
<em>So now the question turns to:</em>
3 (7）+ 8 × 4
<em>now you are going to do mulitiplication from left to right.</em>
<em>so 3 times 7 equals to 21.</em>
<em>Your question is now :</em>
21 +8 × 4
<em>4 times 8 equals to 32.</em>
<em><u>21 +32= 53.</u></em>
3 · 2³- 12 ÷ 4 + 7
<em>According to BEDMAS.</em>
<em>You are starting with brackets, but since there is no brackets in this question, you can start with the exponet first.</em>
2³= 2 ×2× 2= 8
<em>The new question:</em> 3 · 8 - 12 ÷ 4 + 7
<em>Next is multiplication or dividtion from left to right.</em>
<em>3 times 8 equals to 24.</em>
24 - 12 ÷ 4 + 7
<em>12 divided by 4 is 3.</em>
24-3 +7
21 +7
28.
<u><em>Final answer is 28.</em></u>
