Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees none of the other lines add up to 180 degrees and are also part of a vertical pair

Frazer scores 70% in a spelling test with 20 questions. How many did he get right? Show me your work.
ladessa [460]
Fraser got 14 questions right

questions correct 70/5 = 14
—— ——
total questions 100/5 = 20

therefore he got 14 questions right

you divide 100 by 5 because percents are always out of 100 and that gets you 20 which is how many questions the spelling bee had

then you do the same to the top (divide by 5) and get 14

14/20 questions were answered right
70% of the questions were correct

Create a system of linear equations with one solution. In your final answer, include the system of equations and the graphs of t
GrogVix [38]

Answer:

<u>System of equations</u>

x + y = 5

y - 2x = -4

(x,y) = (3,2) --- solution

See attachment for graph

Step-by-step explanation:

Solving (a): Linear equations with 1 solution

The only condition to this is that, the system must have 1 solution.

Other than that, there is no other condition.

A linear equation is represented as:

ax + by= c

For the equation to have 1 solution;

a_1 * b_2 \ne a_2 * b_1

And example of such equation is:

x + y = 5

y - 2x = -4

Solving (b): The graph

See attachment for graph

The solution is the point of intersection of both lines of the graph. So, we have:

(x,y) = (3,2)
