Answer:
1197 miles.
<h3>Step by step explanation:</h3>
Speed(s) = 63 mph
Time(t) = 19 hours
Distance(d) = ?
We know,
D = S × T
= 63 × 19
= 1197 miles
Answer:
1.2675 × 10^37.
Step-by-step explanation:
you would have to first multiply 3.9 x 3.25 =12.675. It is not in scientific notation so you would have to change the decimal 1.2675 x 10^37
Given expression:
.
First we would apply exponents of exponent rule on the top.

Therefore,

=
Applying quotient rule of exponents.


= 
<h3>Therefore,

is the simplified form of the expression

</h3>
The answer is -2.75
-0.5m + 2.75m - 5m
(-0.5m + 2.75m) -5m
2.25m - 5m = -2.75
