Answer:
Wheres the statements?
Step-by-step explanation:
Answer = A.
Set up your equation, then switch the variables with numbers to find which one works.
2x + y = 3; 2(1.2) + .6 = 3
x + y = 1.8; 1.2 + .6 = 1.8
Answer:
C.
$5,509.50
Step-by-step explanation:
The computation of the estimated total tax due in case of taxable income for $43,500 is shown below:
Since in the question the income brackets and based on the income the different tax is to be charged
For $9,525, the 10% tax is charged i.e
= $952.50
Upto $38,700, the 12% tax is charged i.e
= $3,500.88
The remaining amount left is
= $1,055.78
Now the total tax due is
= $952.50 + $3,500.88 + $1,055.78
= $5,509.16 approx i.e $5,509.50
Answer:
The answer to your question is x = 2, y = -1, z = 3
Step-by-step explanation:
Data
x + y + z = 4
x - 2y - z = 1
2x - y - 2z = -1
Solve the system of equations
| 1 1 1 |
| 1 -2 - 1 |
Δ = | 2 -1 -2| = (4 - 1 -2) - (-2 + 1 -4) = 1 + 5 = 6
| 1 1 1 |
| 1 -2 -1 |
| 4 1 1 |
| 1 -2 -1 |
Δx = |-1 -1 -2| = (16 - 1 + 1) - (-2 + 4 + 2) = 16 + 4 = 12
| 4 1 1 |
| 1 -2 -1 |
| 1 4 1 |
| 1 1 -1 |
Δy = | 2 - 1 -2 | = (-2 -1 -8) - (-8 + 1 + 2) = -11 - 5 = -6
| 1 4 1 |
| 1 1 -1|
| 1 1 4|
| 1 -2 1|
Δz = | 2 -1 -1| = (2 - 4 + 2) - (-1 -1 -16) = 0 + 18
| 1 1 4|
| 1 -2 1|
Find x, y and z
x = Δx/ Δ = 12/6 = 2
y = Δy/Δ = -6/6 = -1
z = Δz/Δ = 18/6 = 3
Answer:
0.51km × 1000 = 510m
510m × (3×7) = 510m × 21 = 10710m in whole
Step-by-step explanation:
first we transform km to m (multiply by 1000)
then we count how much days are in three weeks ( 3 weeks × 7 days)
then we just multiply the meters per day × the days
99% it's true
