Solve for x by simplifying both sides of the equation, then isolating the variable.
Exact Form would be or look like
x=9/5, -3/5
Answer:
a
is the right one
Step-by-step explanation:
Answer:
3x+2y
Step-by-step explanation:
Find the rectangles attached
Area of a rectangle = Length * Width
A = A1+A2
given
A = 30cm²
A1 = 3 * x
A1 = 3x
A2 = 2*y
A2 = 2y
Substitute
30 = 3x+2y
Hence the required equation is 3x+2y = 30

five hours = 45$
1 hour = 9$
7 hours = 63$
Answer:
2000 eels
Step-by-step explanation:
Let us represent the total estimate of the eels = x
She returns the 50 eels to the lake.
The next day Hannah catches 400 eels, of these 400 eels, 10 are ringed.
To solve the above question, we have the following:
50/x = 10/400
Cross Multiply
10x = 50 × 400
x = 50 × 400/10
x = 2000 eels
Therefore, the total estimate of the eels in the lake = 2000 eels
