Answer:
The length of each side of the square is 5 meters
Step-by-step explanation:
<u><em>The correct question is</em></u>
A figure is formed by a square and a triangle. total area is 32.5 m^2. the area of the triangle is 7.5 m^2. what is the length of each side of the square?
we know that
The total area of the figure is equal to the area of triangle plus the area of square
so
The area of square is equal to the area f the figure minus the area of triangle
Let
A ----area of the square
Find the length side of the square
Remember that the area of the square is
where
b is the length side of the square
substitute
square root both sides
therefore
The length of each side of the square is 5 meters
Answer:
4(6+7) GCF: 4
Step-by-step explanation:
Start by getting one of the equations in terms of one variable, in this case lets put the first equation in terms of y
2x+y=3 ---> y=3-2x
now we plug that into the second equation
5x-2y=12 ---> 5x-2(3-2x)=12
we can then multiply and simplify
5x-2(3-2x)=12 ---> 5x-6+4x=12 ---> 9x-6=12 ---> 9x=18 ---> x=2
we can now plug x=2 into an equation to solve for y
2(2)+y=3 ---> 4+y=3 ---> y=-1
It’s 7 because you round it
Since d=9.5h is her rate on saturday
so if she babysit for 6 hours on friday she earns d=9.5(6)=57
she babysat of friday and got 63 for 6 hours
so she earned more amount per hour on friday
