Answer:
1. Solve the equation using addition or subtraction.
[tex]4=q+13[/tex]
Taking like terms on one side, we get
[tex]4-13=q[/tex]
=> [tex]-9=q[/tex]
or [tex]q=-9[/tex] (option C)
2. Solve the equation using addition or subtraction.
[tex]5.5= -2+d[/tex]
Taking like terms on one side, we get
[tex]5.5+2=d[/tex]
So, [tex]d=7.5[/tex] (option B)
3. Solve the equation using multiplication or division
[tex]-7y=28[/tex]
Dividing both sides by 7, we get
[tex]-y=4[/tex]
or [tex]y=-4[/tex] (option A)
4. Solve the equation using multiplication or division
[tex]-13=\frac{m}{-5}[/tex]
Cross multiplying -13 and -5 to get the value of m
[tex]m=(-13)(-5)[/tex]
[tex]m= 65[/tex] (option C)
