Answer:
Step-by-step explanation:
The given expression is
2 1/3-1 2/3
These are mixed fractions. It has whole numbers and proper fractions.
We would start by subtracting the proper fractions. Both proper fractions have the same denominators. It becomes
1/3 - 2/3
The issue here is that 1 s lesser than 2. Subtracting 2 from 1 would result in a negative number. So we would borrow from the whole number, 2
The whole number, 2 can be expressed as (1 + 1). 1 whole represents 3. So we add 3 to the 1 in the numerator. The fraction becomes 1 (3+1)/3 = 1 4/3
The expression becomes
1 4/3 - 2/3
Subtracting the fractions, it becomes
4/3 - 2/3 = 2/3
Subtracting the whole numbers, it becomes. 1 - 0 = 1
The result becomes
1 2/3
Answer:
b. Sarah has driven "x" miles of a 35 mile trip.
Step-by-step explanation:
B makes the most sense because the reader does not know how many miles she has driven.
The correct option in A.
Lines 20-21 ("Nobody . . . died")
<h3>Briefing:</h3>
Nobody has succeed in this thing , and many have died.
This line belong to the 20-21 line for the phrase When fictional Swedish scientist went to the north pole for set up hydrogen- powered balloon.
<h3>Who is Swedish scientist ?</h3>
Only hydrogen offers helium-like lift; in fact, hydrogen offers 7-8% more lift than any other gas. In atmospheric sounding balloons outside of North America, hydrogen is frequently employed.
<h3>What is hydrogen- powered balloon?</h3>
Arrhenius, who was originally a physicist but is frequently referred to as a chemist, was one of the pioneers of the field of physical chemistry. He was the first Swedish Nobel laureate when he won the Chemistry Prize in 1903.
<h3>Why did they stop using hydrogen in balloons?</h3>
Despite being lighter than air, hydrogen is flammable, and since oxygen is present in the air, there is a chance of an explosion and fire. Since helium is a non-combustible gas and lighter than air, it is frequently used to fill balloons.

Answer:
a. 156°
Step-by-step explanation:
The marked angle at P is the average of the arcs intercepted:
((13x)° + (5x+10)°)/2 = (10x -7)°
(18x +10)/2 = 10x -7 . . . . simplify a bit
9x +5 = 10x -7 . . . . . . . . simplify more
9x +12 = 10x . . . . . . . . . . add 7
12 = x . . . . . . . . . . . . . . . . subtract 9x
Now, use this value to find (13x)°.
13x° = 13(12)° = 156° . . . measure of arc DC
