Answer:
6.3
Explanation:
To get from 4.5 to 5.4, you need to add 0.9. If you add 0.9 two more times, you get 7.2. Therefore, the middle term should be 6.3. I don't know if you made a typo and forgot the decimal when writing the options cause it says "63", but I believe the answer is 6.3.
8,000,000 pennies equals $80,000. 1/.05=20
20 x $80,000=$1,600,000 more that the bank was able to lend

Answer:
3/12 or 1/4
Explanation:
There are 12 balloons and 3 are green
Answer:
(x, y) = (-0.6, 0.8) or (1, 4)
Step-by-step explanation:
Use the second equation to substitute for y in the first.
(x -1)² +((2x +2) -2)² = 4
x -2x +1 + 4x² = 4 . . . . . . . eliminate parentheses
5x² -2x -3 = 0 . . . . . . . . . . subtract 4, collect terms
Now we can rearrange the middle term to ease factoring by grouping.
(5x² -5x) +(3x -3) = 0
5x(x -1) +3(x -1) = 0
(5x +3)(x -1) = 0
The values of x that make these factors zero are ...
x = -3/5, x = 1
The corresponding values of y are ...
y = 2(-3/5)+2 = 4/5 . . . . for x = -3/5
y = 2(1) +2 = 4 . . . . . . . . for x = 1
The solutions are: (x, y) = (-3/5, 4/5) or (1, 4).

A graphing calculator verifies these solutions.
The value of the a in the quadratic equation is 4.
According to the statement
we have given that the x = 1 and the given equation is (2x)^2=a
And we have to find the value of A here.
So, For this purpose, we know that the
A quadratic equation is an equation of the second degree, meaning it contains at least one term that is squared.
And the given quadratic equation is
(2x)^2 = a
we know that the x = 1 and put the value of x in it then
(2(1))^2= a
(2)^2= a
a = 4.
Now for rechecking of the value, put a = 4 in the given equation then
(2x)^2 = a
Put a = 4
Then
(2x)^2 = 4
2x = 2
And the value of x become
x = 1.
Which equal to the given value of the x which is 1.
So, The value of the a in the quadratic equation is 4.
