A system of linear equation consists of two or more linear equations with the two or more same variables. Such equations are called system of equations (or) simultaneous equations (or) a pair of equations.
Example:
x + y = 5 is one linear equation.
2x – y = 4 is another linear equation.
But x + y = 5, 2x – y = 4 together they form system of linear equation.
The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.

Answer:
50%
Step-by-step explanation:
Let the total number of trees be T and suppose that this is made up of eucalyptus trees E and other kinds of trees, O.
Then E+O=T, and since 99% of the trees are eucalyptus trees, EE+O=0.99.
Therefore
0.99E+0.99O=E
0.01E=0.99O
E=99O.
Suppose we reduce the number of eucalyptus trees by some amount x and that the remaining number of eucalyptus trees are now 98% of the total trees.
Then we would have E−x(E−x)+O=0.98.
Therefore,
0.02(E−x)=0.98O
0.02E−0.02x=0.98O
0.02x=0.02E−0.98O
x=E−50(0.98)O
x=E−49O
x=E−49(E99)
x=5099E≈0.505050...×E.
So we end up removing a little over half of the eucalyptus trees. EDIT: Forgot to mention - removing 50.505050...% of the eucalyptus trees means that we are removing 0.50505050....×0.99T which is 0.5T or half the trees in the neighborhood.
Answer:
0.125, 0.25, 0.4, 0.666...
Harley, Olga, Kayla, Karla
Step-by-step explanation:
Change each number into a decimal, then compare them.
Karla saved 2/3 = 0.666...
Olga saved 25% = 0.25
Harley saved 1/8 = 0.125
Kayla saved 0.40 = 0.4
From least to greatest:
0.125, 0.25, 0.4, 0.666...
