Answer:
Addition Property of Equality
Step-by-step explanation:
So we had:

And then we got:

We did this by adding 2 to both sides of the equation. When we added 2, the left side cancelled and the right side equated to 9:

Since we added 2 to both sides, this is an example of the addition property of equality.

Answer:
Step-by-step explanation:
Actually Welcome to the Concept of the linear equations..
Here given value of x= 5 and y =1 , so we get as,
5a + b = 38 and 5b - a = 8
so, now we multiply equation no. 2 by 5 all over.
==> 25b - 5a = 40....(1)
hence adding new equation and equation no. 1
26b = 78
b = 78/26
hence b = 3 , and a = 7
Answer:
Step-by-step explanation:
You need to first put the numbers in suitable catagories
0-120
120-130
130-140
140-150
then figure out the frequency of them
0-120=4
121-130=20
131-140=2
141-150=2
then put in a graph(sry its not very good i was in a rush)
