I can tell you that the opposite side of the triangle (the top) is also 11 those are two congruent sides
Answer:
A = yd²
Step-by-step explanation:
the area ( A) of a rectangle is calculated as
A = length × width
= ×
=
= yd²
Answer:
$744.60
Step-by-step explanation:
Change 12.4% to a decimal by moving it two places left or you can multiply it by 100. After converting it to a decimal, you will have 0.124 as a decimal. Multiply the decimal and the $850.
850 x 0.125 = 105.40.
Now subtract.
850 - 105.40 = 744.60
Simultaneous equations can be solved using inverse matrix operation.
The complete steps of Jacob's solution are:
We have:
Calculate the determinant of
So, the inverse matrix becomes
Replace the first column with to calculate the value of x
So, we have:
Replace the second column with to calculate the value of y
So, we have:
Hence, the complete process is:
