(3+x)+x=10.5

Simplify

2x = 7.5

x = 3.75

Plug in for x

(3 + 3.75) + 3.75 = 10.5

6.75 + 3.75 = 10.5

The heavier packet of fruit is 6.75 kg.

Which is the equation of the line with slope 0 passing through the point (-3,-1)?
madreJ [45]

When a line has a slope of zero it means that it is horizontal. This means that all the x values have the same y values. In this case it means that the y value is always -1.

The equation for this line is...

y = -1

Hope this helped!

HELP!!!!! part A: Ms.Donaldson earns $18.80 per hour for the first 40 hours she works in a week. She earns 1 1/2 times that amou
Elena-2011 [213]

Answer: A. $907.10

B. $628.236

Step-by-step explanation:

For the first 40 hours, Ms.Donaldson will earn: = 40 × $18.80 = $752.0

We are informed that Ms.Donaldson worked 45.5 hours, this means that she worked an extra 5.5 hours. The amount paid for the extra hour will be:

= 5.5 × 1.5 × 18.8

= $155.10

The amount she earned will be:

= $752.0 + $155.10

= $907.10

B. A health incurrence payment of $34.55 was deducted from Ms.Donaldson's earnings for the week. Therefore, the amount she will have after the deduction will be:

= $907.10 - $34.55

= $872.55

After the incurrence deduction, payroll taxes equal to 28% of the balance were deducted. What was the amount that Ms.Donaldson received afterwards?

This will be:

= $872.55 - (28% × $872.55)

= $872.55 - (0.28 × $872.55)

= $872.55 - $244.314

= $628.236
