-(7-2x) + 7 = -7 What is X?

1 answer:
Mekhanik [1.2K]2 years ago

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}

How do I solve these equations
Sever21 [200]
You need to know the properties of each function.
Tan is opposite (y) over adjacent (x).  Sin>0 means that sin is positive, therefore, it is located on either quadrant 1 or 2. Tan=4/3  so it is located in quadrant 1.
The side of the triangle must be Adjacent=3  opposite=4 and hypotenuse=5
Now, you are asked to find the half angle of Cos which is 
\sqrt{\frac{1+cos}{2} }
By following the formula, cos=3/5 then:
\sqrt{ \frac{1- \frac{3}{5} }{2} }    Multiply everything (inside the square          \sqrt{ \frac{5+3}{10} }                  root) by 5
\frac{2 \sqrt{2} }{ \sqrt{10} }
\frac{2 \sqrt{20} }{10}                Then just simplify
\frac{ \sqrt{20} }{5}      The answer is Square root of 20 over 5

A jet ski rental charges A flat rate of $75 ,plus an additional $60 per hour you want to spend less than $200. for how many hour
cluponka [151]
The equation to solve would be setting

60×- the m plus 75,the b set to 200 the maximum that's wanted to be used. the equation will look like this

200=60x+75

-75. -75

125=60x
125/60 60x/60

2.08=x

and since you cant round the time the answer will be left at 2
