Answer:
I think you mispelled something there... if the system of equation involves 2x-3, the answer is x = 6/5 and y = -27/5
Step-by-step explanation:
- 7x+3 = -2x-3
1. move -3 to the other side (so add it on both sides)
2. move 7x to the other side (in order to combine like terms)
3. Solve for x (Divide 5 by both systems)
4. Plug x into one of the equations to find y
- 2 * (6/5) -3 = -27/5
- y = -27/5
Answer:
318
Step-by-step explanation:
The rate of 5.3% is an annual rate, and specifies the amount of interest earned in a 12-month period by the principal amount of the CD. The interest amount is found by multiplying the interest rate by the principal amount.

<h3>penalty</h3>
The amount of the penalty is 5.3% of 6000:
0.053 × 6000 = 318
Wendy paid a penalty of 318 for her early withdrawal.
Answer:
82
Step-by-step explanation:
For this problem you would first round everything. 9.03 becomes 9, 19.87 becomes 20, 3.11 becomes 3 and 4.97 becomes 5. You then just do the problem. 9 + 20 = 29, multiplied by 3 makes 87, 87 - 5 = 82.
4x+8=6x-14
-4x. -4x
8=2x-14
+14 +14
22=2x
/2. /2
11=x
Since Emily is walking at a constant speed, we can solve this using proportions, equating ratios of distance/time.
The first ratio is 3/4 miles/1/4 hour
The second ratio is 1 mile/ x hour
Equating the two ratios: 3/4 / 1/4 = 1/x
3 = 1/x
x = 1/3 hour
