First, express the mixed numbers as simple fractions:
1 3/5 = (1x5+3)/5 = 8/5
1 9/10= (10x1+9)/10 = 19/10
Add both:

The sum is greater than 3 and less than 4.
Answer:
Ques 1 - 
Ques 2 - 
Step-by-step explanation:
Ques 1: From the table, we see the relation,
5 = 2 × 2 + 1
9 = 2 × 4 + 1
13 = 2 × 6 + 1
17 = 2 × 8 + 1
21 = 2 × 10 + 1
That is, the relation from the table is given by,
, where x is the input and y is the output.
Hence, the required equation is
.
Ques 2: From the table, we see that,
2 = 12 × 0 + 2
14 = 12 × 1 + 2
26 = 12 × 2 + 2
38 = 12 × 3 + 2
50= 12 × 4 + 2
That is, the relation from the table is given by,
, where x is the input and y is the output.
Hence, the required equation is
.
Answer:
73
Step-by-step explanation:
72 - 35 = 107
180 - 107 = 73
107 + 73 = 180
Answer:
I can't draw the graph for you here, but the y intercept is 3, and the slope is -1.
Step-by-step explanation:
First you plot a point on the y axis at 0,-3
Then you want to do a rise over run, doing -1,1 until you get enough points to graph the line.
