Answer:
8+7x+4y
Step-by-step explanation:
15-7 is 8
12x-5x is 7
Put it all together to get 8+7x+4y
Let the total be x
1/6x=3
x/6=3
x=18
therefore Ramal's stamp has 18 pages
Once the numbers have the same base and exponents, we can add or subtract their coefficients.Here are the steps to adding or subtracting numbers in scientific notation:Determine the number by which to increase the smaller exponent by so it is to the equal larger exponent
Put them into y=mx+b
y=1/3x -1
y=2/3x-4
Graph them. Where they touch is your answer. No touch? No solution. Same line? Infinite solutions.
Second set: Same thing.
Solution to first set is (9,2)
Answer:
The arrangement of the given equation in the slope - intercept form are

Step-by-step explanation:
Given:
x + y = 4 and
y - 2x = -5
Slope - intercept form :

Where,
m is the slope of the line.
c is the y-intercept.
When two points are given say ( x1 , y1 ) and ( x2 , y2) we can remove slope by
Slope,

Intercepts: Where the line cut X axis called X- intercept and where cut Y axis is called Y- intercept.
So, the Slope -intercept form of
x + y = 4 is 
and
y - 2x = -5 is
