## anonymous one year ago Find the value of b using the given information A-5.4=8.3 and b=4a

1. anonymous

Is $$A$$ the same thing as $$a$$?

2. anonymous

so b=4a if we rearrange it we will get

3. anonymous

$a=\frac{ b }{ 4 }$

4. anonymous

now $a-5.4=8.3$

5. anonymous

plug in the value of a in this equation

6. anonymous

$\frac{ b }{ 4 }-5.4=8.3$

7. anonymous

now solve for b , let me know if u need help with that too :)

8. anonymous

Need help

9. anonymous

ok so $\frac{ b }{ 4}=8.3+5.4$

10. anonymous

$\frac{ b }{ 4 }=13.7$

11. anonymous

$b=13.7 \times 4$

12. anonymous

$b=54.8$
