SOLVE FOR X PLEASE
10x+50+80=180

x= 5

Step-by-step explanation:

10(5)+50+80=180

Multiply the 5 by 10

10*5=50

50+50+80=180

Isolate the variable by dividing each side by factors that don't contain the variable.

x=5

Step-by-step explanation:

10x+50+80=180

combine 10x(50+80)=180, 10x+130=180

subtract 10x(130-130)=(180-130), 10x=50

divide 10 by 50 to find x=5

hope the step by step helps

geometric series converge the common ratio r has magnitude less than one.

which is equivalent to

for the example we need

|2-x| < 1

-1 < 2-x   and 2-x < 1

x < 3 and x > 1

we can write that

answer: 1 < x < 3

1a. common ratio r=250/25=10 > 1     diverges

1b.   r=50/100=1/2 converges

when these converge they converge to

where a is the first term.

answer: 200

1c. r=-1   so it's not the case that |r| < 1.     diverges

2a. x is the common ratio so we converge when |x|< 1

2b.   r=-10x / -2 = 5x.

we converge when

|5x| < 1

|x| < 1/5

2c.   r=3-2x

-1 < 3-2x and 3-2x < 1

-4 < -2x and 2 < 2x

x < 2 and 1 < x

1 < x < 2

2d. [/tex] r=-48x^3/12 = 4x^3[/tex]

|4x^3| < 1

|x^3| < \frac 1 4

|x| < 4^{-1/3}

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
