A would equal 4 because you would first convert the mixed numbers into improper fractions, then move the constant to the right, and finally add the factions
a-2(1/2)=1(1/2)
a-(5/2)=(3/2)
a=(3/2)+(5/2)
a=4
Answer:
A solution to a system of equations is a set of values for the variable that satisfy all the equations simultaneously. In order to solve a system of equations, one must find all the sets of values of the variables that constitutes solutions of the system.
Step-by-step explanation:
The ratio of the surface areas are 361/81.
surface area is a 2D measurement.
similarity is a 1D ratio.
square root of 361/81 is 19/9.
Ex: y=2x+4 <span>3x+y=9 <--Simply plug y into the second equation here and solve for x. When you find the solution for x, you can plug the solution to x into the 2nd equation to find y....Hope this helps!!!</span>
