Answer:
Perimeter: 60.6cm
Area: 212.3cm
Step-by-step explanation:
When calulating the perimeter, you are adding the length of all the sides together. Since the figure is a rectangle, two two pairs of sides will be different lengths. Solving is as follows:
P= 11+11+19.3+19.3 or P=11(2)+19.3(2) =60.6
With area, you need the total amount of mass, so you would multiply two sides. In this case, the two are 11cm and 19.3cm.
A= 11(19.3)cm =212.3
Answer:
The first option is correct, (-2y + 5x) / (3x - 2y)
Step-by-step explanation:
Answer:
There were 58 students in each bus.
Step-by-step explanation:
Total number of students x=
237
Number of students who travelled by car =
5
∴ Number of students who travelled by bus =
237
−
5
=
232
Presuming the buses to have the same capacity, and knowing that there were four buses, the number of students in each bus can be expressed as:
x
=232
÷4
x
=
58

Answer:
No Solution
Step-by-step explanation:
Substitution means to replace the variable with the one provided, in this problem we have been given y = 2x, so we would simply replace the y variable in the second equation with 2x.
Review over what we have been given
y = 2x
-6x + 3y = 16
As explained above, substitute the y value in the second equation with the contents of the first equation.
-6x + 3(2x) = 16
In this step, you can solve for the value of x.
-6x + 6x = 16
Since both of the x variables cancel out, we cannot find the value of x since it equals to zero, which also means we cannot find the value of y.
0 = 16
Generally, we find the value of our x, then we would input that into the first equation to find the value of y.
But as stated above, there is no value of x, therefore there is no solution.
