You didn't write what to do with the fraction but I think you meant to ask to simplify it:
38b/-19
Multiply - 19 from top and bottom :
-2b
Bill = $25.85
Tips = 15% x $25.85 = $3.88
Tax = 6.25% x $25.85 = $1.62
Total amount = $25.85 + $3.88 + $1.62 = $31.35

Answer: He will spend $31.35 in total.

Answer: on the number line put -1.50 (1 and a half (1 1/2))
Step-by-step explanation:
$1.50 more than his account is $200.
the balance should be $-1.50
on the number line put -1.50
<u>Answer:
</u>
The standard form of 
is 20,00,0000
<u>Solution:
</u>
Given that ---- eqn 1
To write in standard form,
We know that 
.So 
becomes 
.
Now eqn 1 becomes,
----- eqn 2
We know that 
, so 
Now eqn 2 becomes,
---- eqn 3
Expanding 
:
Here 10 is the base term and 7 is the exponent value. So base term 10 is multiplied by itself 7 times.
Now eqn 3 becomes,
= 20,00,0000
Hence the standard form of is 20,00,0000
