since you already know how to get the slopes and equation, let's do the equations of each of these two without much fuss.
then we'll have two equations, namely a <u>system of equations of two variables</u>, and we'll solve it by <u>substitution</u>.
first equation is
second equation is
now, let's recall, let's substitute "y" in the second equation,
Answer:
Dennis need 288.91 square inches of construction paper for his project.
Step-by-step explanation:
Dennis is cutting construction paper into rectangles for a project.
He needs to cut one rectangle that is 12 inches times 15 1/4 inches
First convert the mixed fraction to improper fraction
So the area of 1st rectangle is
He needs to cut another rectangle that is 10 1/3"" x 10 1/4""
The symbol " means inches
First convert the mixed fraction to improper fraction
So the area of 2nd rectangle is
The total construction paper needed for this project is
Therefore, Dennis need 288.91 square inches of construction paper for his project.
Answer:
67.5
Step-by-step explanation:
Because I know
For the first equation x = 7 and y = - 14/9 and for the second equation x = 7 and y = 7/6 , Hope it helps!
