Answer:
midpoint shows in one place while bisector covers most area
Answer:
No, Angela is not correct.
As the method Jim was performing will also lead to the solution.
Step-by-step explanation:
We are given first equation as:
Ax + By = C
Second equation is:
Dx + Ey = F
Jim solved the equation as:
He begins by multiplying equation (1) by D and equation (2) by A.
and so by subtracting both the equations he will obtain a value of y.
and then put the y-value in any of the given two equations to obtain the value of x.
Angela Method:
you should have multiplied equation (1) by E and equation (2) by B.
and when she will subtract both the equations she will get the value of x first and then when she will put the value of x in any of the given equation she will obtain the value of y.
But both will get a value for x and y.
Hence, the method Jim was performing was also correct.

2600 + 3100 + 2800 + 3200 = 11700 (monday to thursday)
3000 x 5 = 15000 (mon. to fri. need to sell at or above)
15000 - 11700 = 3300 (friday needs to sell at least 3300 to get promotion)
answer
D. $3,300
2)
$6155 - $5944 = $211
answer is
B. $211
Answer:
The work has Been done is 2503.12 J .
Step-by-step explanation:
Formula for workdone is given by
Workdone = Force × Distance
As w = mg
Where m is the mass , g is the acceleration of gravity .
As given
Ben Pumpiniron applies an upward force to lift a 129-kg barbell to a height of 1.98 m at a constant speed.
m = 129 kg
g = 9.8 m / s²
Putting in the w =mg
w = 129 × 9.8
= 1264.2 kg m / s²
(As given in the question force is constant thus force doing the work is equal to weight .)
Thus
Force = 1264.2 kg m / s²
Workdone = Force × Distance
= 1264.2 × 1.98
= 2503.12 J (Approx)
Therefore the work has Been done is 2503.12 J .
Step-by-step explanation:
just subtract it
answer is 122.709
