Answer: x= $-\frac{7}{2} = -3 \frac{1}{2} = -3.5$

Step-by-step explanation:

−(7−2x)+7=−7

To find the opposite of 7−2x, find the opposite of each term.

−7−(−2x)+7=−7

The opposite of −2x is 2x.

−7+2x+7=−7

Add −7 and 7 to get 0.

2x=−7

Divide both sides by 2.

$x = \frac{-7}{2}$

Fraction −7/2 can be rewritten as −2/7 by extracting the negative sign.

$x = -\frac{7}{2}$

A bag has six balls labeled a,b,c,d.e and f . One ball will be randomly picked, and its letter will be recorded as the outcome.

Dvinal [7]

<h3>Sample space = {a,b,c,d,e,f}</h3><h3>Event space = {a,c}</h3>

We simply list all of the letters mentioned as they are the possible outcomes. We can only pick one item from the sample space. The event space is the set of outcomes where we want to happen (picking either an 'a' or 'c').

Answer:

$\large{ \tt{❃ \: EXPLANATION}} :$

We're provide - Sin θ = $\frac{12}{37}$ which means 12 is the perpendicular & 37 is the hypotenuse [ Since Sin θ = $\tt{ \frac{p}{h}}$ ] . We're asked to find out tan θ ].
