Answer:
62.4
Step-by-step explanation:
1. 1.3x+37.44=1.9x
2. 1.3x+37.44-1.3x=1.9x-1.3x
0.6x=37.44
3. x=37.44/0.6=62.4

Step-by-step explanation:
Sally purchased a TV from Rent-A-Center. She made her a down payment of $8.35x before she took her TV home. The down payment was the same amount as the payments she would continue to make monthly. Every month after that she made payments of $4.25x+36. Solve for x. (x=9, payments are $75.15)
Answer:
The value of x = 5 and y =2
Step-by-step explanation:
Given: In parallelogram DEFG
DH = x+1 , HF= 3y , GH =3x-4 and HE = 5y+1.
In a parallelogram DEFG as shown below in the figure,
let H be the midpoint of parallelogram where the diagonals DF and GE of a parallelogram bisect each other.
then,by definition of parallelogram;
DH = HF and
GH=HE
Since, DH =HF
Substitute the given values above we get;
x+1 = 3y
or
x-3y = -1 ......[1]
and
GH = HE
3x-4 = 5y+1
or
3x - 5y = 5 ......[2]
On solving equation [1] and [2] simultaneously we get;
y =2
Substitute the value of y=2 in [1] we have;
x -3(2) = -1 or
x-6 = -1
Add 6 to both sides of an equation:
x-6+6 = -1+6
Simplify:
x = 5
Therefore, the values of x and y is; 5 and 2
Answer:
a₁ = 15 and common difference = 8 so the formula is:
aₙ = 15 + (n - 1) * 8
= 8n + 7
