Answer:

x = 40

Step-by-step explanation:

x + 100 + x = 180 {Straight line angles}

2x + 100 = 180 {subtract 100 from both sides}

2x = 180 - 100

2x = 80 {Divide both sides by 2)

x = 80/2

x = 40

Suppose the system below is consistent for all possible values of f and g. What can you say about the coefficients c and d? Just

morpeh [17]

Answer:

The answer is " $d \neq 3c,$ f and g are arbitrary".

Step-by-step explanation:

The matrix of the device is increased

$\left[\begin{array}{ccc}1&3&f\\ c&d&g\\ \end{array}\right]$

Reduce the echelon row matrix

$\left[\begin{array}{ccc}1&3&f\\ c&d&g\\ \end{array}\right] \\\\R_1 \leftrightarrow R_2 \\\\\frac{R_2 -1}{C R_1 \to R_2} \sim \left[\begin{array}{ccc} c&d&g\\ 0 & \frac{3c-d}{c}& \frac{cf-g}{c}\\ \end{array}\right]$

Therefore, if 3c $\neq$ 0 is d $\neq$ 3c, the device is valid. Therefore d $\neq$ are arbitrary 3c, g and f.

Someone solve this equation much appreciated!

daser333 [38]

Answer:

$\frac{2A}{h} = b$

Step-by-step explanation:

this can be done by simple manipulation .
in the given equation, A is the subject.
so, by the above statement you can understand the meaning of making something as a subject.

given equation: A = 1/2 bh

multiply both the sides by 2,

2A = bh

divide both the sides by h,

$\frac{2A}{h} = b$

so, the required form is : $\frac{2A}{h} = b$

Can someone help me ? If Tina can type a paper in 5 hours and together she and Tyra can type the paper in 2 hours, how long woul

SpyIntel [72]

Answer: 3 1/3 hours

Step-by-step explanation:

Tina rate: 1/5 job/hr

Together rate: 1/2 job/hr

Tyra rate: 1/x job/hr

---------

Equation:

rate + rate = together rate

1/5 + 1/x = 1/2

2x + 10 = 5x

3x = 10

x = 3 1/3 hrs (time for Tyra to do the job alone)
