Hope this helps
Step-by-step explanation:
29,30,31 is three consecutive interger that add up to 90
The mass of each book in grams if each box weighs 20 kilograms is 2000 grams
- Mass of each box = 20 kilograms
- Total books in the box = 10 books
<h3>Converting kilograms to grams</h3>
1 kilograms = 1000 grams
20 kilograms = 20,000 grams
Mass of each book in grams = 20,000 grams / 10
= 2000 grams

Answer:
Refer the attached figure.
Step-by-step explanation:
Given : System of equation 
To find : Which graph represents the solution to the given system?
Solution :
Equation
plotted with a red line passing through (-1,0) and(0,4).
Equation
plotted with a blue line passing through (0,-3) and(0.75,0).
As their slopes are equal i.e. m=4.
So, the equation of lines are parallel.
There is no solution of the equations.
Refer the attached figure of the equations.
