Answer:
22. [tex]22\frac{1}{2}[/tex]
23. [tex]9x[/tex]
24. [tex]-45[/tex]
25. [tex]10[/tex]
Step-by-step explanation: GEMDAS RULE
For No. 22
Calculate within parentheses: [tex]\left(\frac{3}{2}-6\right)=-\frac{9}{2}[/tex]
- [tex]=12-\frac{9}{2}+15[/tex]
Add and subtract (left to right): [tex]12-\frac{9}{2}+15=\frac{45}{2}[/tex]
- [tex]12-\frac{9}{2}=\frac{15}{2}[/tex]
- [tex]\frac{15}{2}+15=\frac{45}{2}[/tex]
Convert improper fraction to mixed: [tex]\frac{45}{2}=22\frac{1}{2}[/tex]
- [tex]\frac{45}{2}=22\frac{1}{2}[/tex]
For No. 23
Divide the numbers: [tex]6\div \:2=3[/tex]
- [tex]=3x\left(1+2\right)[/tex]
Add the numbers: [tex]1+2=3[/tex]
Multiply the numbers: [tex]\:3\times\:3=9[/tex]
For No. 24
Multiply and divide (left to right): [tex]22\div \:11\times \:6=12[/tex]
Add and subtract (left to right): [tex]=12-57=-45[/tex]
For No. 25
Calculate within parentheses: [tex]\left(44+5\right)=49[/tex]
Multiply and divide (left to right): [tex]49\div \:7=7[/tex]
Add and subtract (left to right): [tex]7+3=10[/tex]
