Answer:

x = -1

Step-by-step explanation:

2x - 7 = 9x

Subtract 2x from both sides: -7 = 7x

Divide both sides by 7: -1 = x

Now plug in 7 for every value of x in the original equation to make sure you are correct:

2(-1) - 7 = 9(-1)

-2 - 7 = -9

-9 = -9

I hope this helps!

A contest on a game show receives -25 points for each wrong answer what integer represents the change in periods after three wro
Paladinen [302]
To represent the change in points, you can think of it in two ways:

1.  You will go down 25 points for every wrong answer, so -25 + -25 + -25 would represent what is happening.  They are all negative, so you keeping moving down in value.  

2.  You can also think of this as 3 groups of -25. 

Both answers are -75.  The answer is negative because the change was down in points.

-75 is the integer that represents this situation.

\frac{1}{6}x+\frac{1}{3}x+\frac{3}{7}(x-(\frac{1}{6}x+\frac{1}{3}x))=x\\\frac{3}{7}(x-(\frac{1}{6}x+\frac{1}{3}x))=27\\\frac{3}{7}(x-(\frac{1}{2}x))=27\\\frac{3}{7}(\frac{1}{2}x)=27\\x=126

Answer:

I think <2 = 37⁰

Step-by-step explanation:

if I remember correctly, if its straight across from it, it must be the same angle.

which means that 1 and 3 must have the same angle, and 2 must have the same angle as the other side, meaning its angle is 37⁰.

Finger [1]
Well to solve for x you simply need to multiply both sides of the equation to isolate x, the answer will be x=34. the second question requires bedmas (brackets, exponents, division and multiplication, addition and subtraction)
It will be 224 no matter if you multiply or divide first
