7x-3 would then be 7(-2) -3. 7 multiplied by -2 would be -14. -14-3= -17
hope this helps
Answer:
125°
Step-by-step explanation:
Supplementary angles sum to 180°
let one angle be x then the larger angle is x + 70, thus
x + x + 7 0 = 180
2x + 70 = 180 ( subtract 70 from both sides )
2x = 110 ( divide both sides by 2 )
x = 55
Hence
larger angle = x + 70 = 55 + 70 = 125°
The cash price of the ring was $ 16,560.80.
Knowing the down payment, the interest rate and the monthly payments, to determine what is the cash price of the ring, the following calculation must be performed, applying the compound interest formula:
- Initial value x (1 + interest rate / compounding times) ^ (years x compounding times) = Compound interest
- X x (1 + 0.072 / 12) ^ 3.5x12 = 360 x 42
- X x 1.006 ^ 42 = 15,120
- X x 1.2856 = 15,120
- X = 15,120 / 1.2856
- X = 11,760.80
- 11,760.80 + 4,800 = Cash price
- 16,560.80 = Cash price
Therefore, the cash price of the ring was $ 16,560.80.
