Answer:
240°
Step-by-step explanation:
The sum of angles in a quadrilateral is 360°, so you have ...
a° +b° +60° +60° = 360°
a° +b° = 240° . . . . . . subtract 120° from both sides
Answer:
Step-by-step explanation:
8 x 8 = 64
4 x 4 x 4 = 64
2 x 2 x 2 x 2 x 2 x 2 = 64
the table:4 represents a linear function.
What is system of linear equations?
The intersections or meetings of the lines or planes that represent the linear equations are known as the solutions of linear equations. The set of values for the variables in every feasible solution is a solution set for a system of linear equations.
Not a Solution
If there is no intersection of any lines, or if the graphs of the linear equations are parallel, then the system of linear equations cannot be solved.
An Endless Number of Options
A set of infinite points exists for which the L.H.S. and R.H.S. of an equation become equal, indicating that a system of linear equations has an infinite number of solutions.
Unique fixing a series of linear equations
For table 4: The slope will be (8-6)/(3-5) = 2/-2 = -1
and (10-8)/(1-3) = 2/-2 = -1
Hence, the table:4 represents a linear function.
For a function to be linear the slope of all the segments should be same.

Answer:
12 eggs
Step-by-step explanation:
If she sends 3/4 to the market
1 - 3/4
4/4 -3/4 = 1/4
She will keep 1/4
1/4 *48 = 12
She will keep 12 eggs
Answer:
1.5
Step-by-step explanation:
the slope is regarded as :
=
this is also known as the <em>gradient </em>, meaning the differences of two y values divided by the differences of the two corresponding x values
take two values on the slope and put in the form ( x,y)
we shall use two points A and B
A = (80 , 100)
B = (20 , 10)
now use the formula:
=
=
also can be represented into an integer form
answer is <u>1.5</u>
