9) Let<br> X-2, x, x+3 <br> be the first 3 terms of a geometric sequence. FInd the value of x..
Reil [10]
Hello,

Let's r the ration

We suppose x ≠0

x=r*(x-2)==>r=x/(x-2)

x+3=r*x==> (x+3)/x=x/(x-2)==>(x+3)(x-2)=x²
==>x²+3x-2x-6=x² ==>x-6=0==>x=6

x-2=6-4=4
x=6
x+3=6+3=9
6=4*3/2
9=6*3/2

Ration 3/2
First term: 4

Lamar works as a tutor for $12 an hour and as a waiter for $14 an hour. This month, he worked a combined total of 100 hours at h
alexdok [17]

Answer:

-2t + 1400

Step-by-step explanation:

If t represents the number of hours Lamar worked as a tutor, the number of hours he worked as a waiter can be represented by 100 - t.

Create an equation to represent the situation:

12t + 14(100 - t) = total earned

Simplify:

12t + 1400 - 14t = total earned

-2t + 1400 = total earned

So, the expression for the amount he earned is -2t + 1400

Pls help :(
Masja [62]

Answer:

similarity

Step-by-step explanation:

look , dude

the two triangles have the following features:

the angle B= angle C = 90 degree

the angle A= the angle F

so  the third angle in the first triangle = the third angle in the second triangle

so you have one condition of similarity which is the three angles are equal

to get the answer for lengths :

ab/fe= constant of proportionality

thus ab/fe=2.5/5=.5

so ac/13=.5 thus ac=6.5

and 6/de=.5 so de=12
