| -4 + 5\2 | - (-x) =-3

Leto [7]

Answer:

x = -4.5

Step-by-step explanation:

<u><em>Solving the equation</em></u> :

$\left\vert -4+\frac{5}{2} \right\vert -\left( -x\right) =-3$

$\Longleftrightarrow \left\vert \frac{-8}{2} +\frac{5}{2} \right\vert +x =-3$

$\Longleftrightarrow \left\vert \frac{-8+5}{2} \right\vert +x =-3$

$\Longleftrightarrow \left\vert \frac{-3}{2} \right\vert +x =-3$

$\Longleftrightarrow \frac{3}{2} +x =-3$

$\Longleftrightarrow x =-3-\frac{3}{2}$

$\Longleftrightarrow x =-\frac{6}{2} -\frac{3}{2}$

$\Longleftrightarrow x = -(\frac{6}{2} +\frac{3}{2} )$

$\Longleftrightarrow x =-\frac{9}{2}$

$\Longleftrightarrow x =-4.5$

Help with this please question 3

MrRissso [65]

3a. Jackson's gross pay for 40 hours is
(40 h)×($12.20/h) = $488.00

3b. An equation for Jackson's pay could be
372.10 = h×12.20
This can be solved for h by dividing by 12.20
372.10/12.20 = h = 30.5
Jackson worked 30.5 hours last week.

3c. The total of hours shown is
(8) + (7 1/4) + (8 1/2) = (8 +7 +8) +(0.25 +0.50) = 23.75
The number of hours missing is the difference between this number and the hours found in part (b).
30.50 - 23.75 = 6.75
There are 6 3/4 hours missing from Jackson's time sheet for last week. This is less than a full day's work, so seems reasonable.

_____
Of course, you know the decimal - fraction conversions:
1/4 = 0.25
1/2 = 0.50
3/4 = 0.75

Well first you add 10 3/5 and 12 1/2 that will equal 22 7/5 then you take away from 35 that is 13 7/5
