Answer:
21
Step-by-step explanation:
If you let j, c, t represent the prices of jeans, camisoles, and t-shirts, respectively, the three purchases can be described by ...
2j +2c +4t = 90.00
1j +0c +3t = 42.50
1j +3c +2t = 62.00
It is convenient to let a calculator solve these equations. It can tell you the row-reduced matrix equations are ...
[[1 0 0 24.5]
[0 1 0 8.5 ]
[0 0 1 6 ]]
which means
flare jeans cost $24.50
camisoles cost $8.50
T-shirts cost $6.00
The values In wxyz are mathematically given as
W=4
y=5
X=0
<h3>What is the values In
XYZ?</h3>
- My one's digit and my tens digit together make up a total of seven.
- My one digit has three more digits than my tens digit does.
Let the equation for the number be: wxyz.
- Digits at tens place = yz
- Diglt at ones place = z
Generally, the equation for is mathematically given as
z+y=7 ......1
y=2+3 .......2
solving further
z+3+z-7
2z 7-3
z=2
Putting the value of z Within the second equation:
y=z+3 y=2+3
y=5
1. The digit in the thousands place of my number is 4, and
2. The digit in the hundreds place is four fewer than the digit in the thousands place.
W=4
X=w-4
x=4-4
X=0
In conclusion, the values In wxyz are
W=4
y=5
X=0

the statement is true because 4 and 7 are different
The statement that best describes the results is in tank 1, the rate at which water is used is higher.
<h3>What is the rate for each tank?</h3>
Tank 1:
- Total of water used/ time
- 177.12/4 = 44.28 gallons per hour
Tank 2:
- 160/ 4 = 40 gallons per hour
<h3>What are the results?</h3>
The rate in tank 1 is higher than the rate in tank 2.
