Answer:
.
Step-by-step explanation:
2.
If angle A = 4x + 12 and x is given as 15 we can say that angle A is an acute triangle because its measure is less than 90° ➡ 4 × 15 + 12 = 72°
3.
if the angle BAM is a right triangle then
4x + 22 = 90 subtract 22 from the both sides
4x = 68 divide both sides by 4
x = 17
In calculating the interest on a car we have a formula
(interest rate/number of payments) x loan principal = interest.
Since, we have:
Interest rate = ?
number of payments = 60 ( 5 year loan x 12 months)
loan principal = 5800
interest = 797.50
We need to derive a formula to find the IR(interest rate)
(interest rate/60) x 5800 = 797.50
IR (5800) / 60 = 797.50
IR (5800) = 797.50 (60)
IR (5800) = 47850
IR = 47850/5800
IR = 8.25 %
Answer:
x=35/4
Step-by-step explanation:
S1- Divide both sides of the equation by the same term
-2100=-240x
-2100/-240=-240x/-240
S2- Simplify
