If He Has 9 Friends, Then Each Of Them Will Get 9 Stamps Which Equals To 81. So There Will Be 2 Stamps Left
// Plug x into the equation
5(0.3)+2y=20
1.5+2y=20
// Subtract 1.5 from each side
2y=18.5
//Divide each side by 2
y=9.25 (C)
The value of x in A is 7 and the value of y in B is -15
<h3>Functions and values</h3>
Functions are represented as a function of variable. Given the following sets of numbers.
A = [3 x 6 1 -8 5] and;
-5A = [-15 35 -30 -5 40 y]
Equate the individual values to have:
-5A= -15
Divide both sides by -5
-5A/-5 = -15/-5
A = 3
Determine the value of y
-5A = y
-5(3) = y
y = -15
Similarly;
5x = 35
x = 35/5
x = 7
Hence the value of x in A is 7 and the value of y in B is -15

A. increase the temperature.
For example, sugar dissolves easily in hot water, but not in cold water(?)
When the lightning occurs 4.5 km away then we will hear after 13.5 seconds and if we hear after 1.5 seconds then we are 0.5 km away from lightning.
Given With each km from the lightning 3 seconds passes.
a) The table of values for distances from 0 to 5 km.
Distances Time
0 0
1 3
2 6
3 9
4 12
5 15
b) The graph of lightning is a linear relation because it is increasing constantly by 3 seconds. f(x)=3x
c) When distance =1 , the time be 3 seconds
when distance =4.5 , the time=3*4.5
=13.5 seconds.
d) When time is 3 seconds = 1km
when time =1.5 seconds , the distance be 1/2=0.5 km.
