Answer:
1. The sum of 4 and x is 7, and to isolate the variable, you move the 4 to the other side and the equation will change into x=7-4, giving us x = 3
2. To solve this inequality, you must isolate the variable x by moving -9 to the other side. To do this, you have to divide 27 by -9, and this causes the direction of the inequality sign to change. After you divide, the inequality changes to this: x<-3
3. since there are no negative numbers involved in this inequality, you divide 3 by 1/4 (or multiply it by 4) to isolate x. this gives us x <= -12
4. To solve this algebraic equation, you must isolate the variable 3x. To do this, you must move -9 to the other side of the equation by adding 9 to the 6. this gives us 3x=15 and x = 5
5. To put x by itself, you subtract 1 by 4, giving you x<-3

Answer:
mRJN = 75°
Step-by-step explanation:
VJA = 15°
If the line VJ would continue through J and stop at a point that we now call Z. Then the new angle ZJN which is a vertically opposite angle to VJA would also be 15°
Angle VJE is supplementary to VJR and therefore also 90°
And if angle VJE is 90°, that means its supplementary angle EJZ is also 90°.
Angle EJN (supplementary to RJN) is simply EJZ - ZJN = 90° - 15° = 75°

A. $1,360
B. $2,720
C. $18,360
D. $19,720
Answers
Answer:
D
Step-by-step explanation:
Answer:
Step-by-step explanation:
We first find out the amount in dollars of interest accrued after 2 years time.
Interest = Prt
where P is the principal, r is the rate and t is time
8% written in decimal fraction → 8/100 → 0.08
Interest = 17000 × 8% × 2
Interest = 1700 × 0.08 × 2
Interest = 2,720 dollars
We add the principal and the interest to get full amount paid, so:
17000 + 2,720 = 19,720
Therefore the answer is D
