Answer:

The answer is 2(x+3)=3 * 2(x-1)-2x

Step-by-step explanation:

full question:

Kim works 3 hours more each day than Jill does, and Jack works 1 hour less each day than Jill does. Over 2 days, the number of hours Kim works is equal to the difference of 3 times the number of hours Jack works and the number of hours Jill works. How many hours does each person work each day? Let x be the number of hours Jill works in one day.

 2(x+3)=3 * 2(x-1)-2x

2(x+3)=6(x-1)-2x

2x+6=4x-6

2x+6-6=4x-6-6

2x=4x-12

-2x=-12

-2x/-2=-12/-2

x=6

If the textbook weight 19.6 newtons on venus, what is the strenght of gravity on that planet?
victus00 [196]

Answer:

8.91m/s²

Step-by-step explanation:

If you were referring to the question :

If a 2.2 kg textbook weighs 19.6 newtons on Venus, what is the strength of gravity on that planet then read on.

Weight is the force of gravity on an object and it can be computed using the formula:

W = mg

where:

W = weight (N)

m = mass (kg)

g = acceleration due to gravity

So we know the weight and the mass of the object, all we do is plug it into our formula and solve for what we do not know.

W = mg\\\\19.6N = (2.2kg)(g)\\\\ \dfrac{16.6N}{2.2kg} = g\\\\8.91m/s^{2} = g

PLEASE HELP I WILL GIVE 100 POINTS!!!!!!!!Given rectangle ABCD ~ HGFE , what is the length of HG ?
never [62]
Since rectangle ABCD is similar to  HGFE, the ratios of the lengths of their corresponding sides are equal. We can infer form our picture that AD is corresponding to EH and DC is corresponding to HG, so lets find the ratios of those corresponding sides and establish a proportion to find the length of HG:
\frac{AD}{EH} = \frac{DC}{HG}
We know that AD=45, EH=27, and DC=15, so lets replace those values in our proportion:
\frac{45}{27} = \frac{15}{HG}
HG= \frac{27*15}{45}
HG= \frac{405}{45}
HG=9

We can conclude that the length of the segment HG is 9.
