Answer:
Step-by-step explanation:
The equations that she wrote are
6x+8y=133
2x=y
The following statements about the system are true
1.Since the cost for each pie is $5 and $9, the first equation should be 5x+9y=133
5. The second equation is correct because there are more 6 inch pies and 2 times a number is always more.
The following statements are wrong because,
2. Because there was no relationship between the number of pipes sold and the size of each pipe.
3. x=2y shows that there are more 8 inches pipes
4. 6 and 8 are just size descriptions. It is only the cost of each size of pipe that related to the total cost
28/4=7 Therefore 1/4 of 28 is 7
The amount earned by Robin is $224
- Given the cost of 182-day T-bill = $160,000
If Robin is discounted to yield 1.96%, the amount yield is expressed as:
The yield of 1.96% = 1.96% of 160000
The yield of 1.96% = 0.0196 * 160000
The yield of 1.96% = $3136
Similarly, if the yield is dropped to 1.82%
The yield of 1.82% = 1.82% of 160000
The yield of 1.82% = 0.0182 * 160000
The yield of 1.82% = $2,912
Amount earned by Robin = $3136 - $2192
Amount earned by Robin = $224
Hence the amount earned by Robin is $224

The two systems have the same solution.
The correct answer is 3) since the first equation of system B is indeed the addition of the first equation of system A and 4 times the second equation of system A.
Answer: 3)
Answer:
x=12
Step-by-step explanation:
This is an equilateral triangle. That means all the angles are equal
There are three angles and they add to 180. 180/3 =60. Each angle is equal to 60
4x+12 =60
Subtract 12 from each side
4x+12-12 = 60-12
4x = 48
Divide by 4
4x/4 =48/4
x=12
