1) -7v + 4(2 - 5v) = -154
Bad White [126]

Answer:

v=6

Step-by-step explanation:

First let's simplify the equation so it will be easier to PEMDAS the equation later.

-7v+4(2-5v)=-154

-7v+8-20v=-154

-27v+8=-154

Now you must isolate the v variable. You do this by subtracting 8 first and then divide by -27.

-27v+8=-154

-27v=-162

v = 6

Please answer circle theorem question.<br> Many thx.
pogonyaev

Answer:

x = 125

Step-by-step explanation:

Tangents from an external point to a circle are congruent , that is

CA = CB

Then Δ ABC is isosceles with base angles being congruent

∠ BAC = ∠ ABC = \frac{180-70}{2} = \frac{110}{2} = 55°

∠ ABC and x are adjacent angles on a straight line and sum to 180° , so

x = 180° - 55° = 125°

Then x = 125

What is negative 9 plus 16/7
jekas [21]

Step-by-step explanation:

-9 + 16/7 = ?

First, find out what 16/7 would make in decimal form, by dividing 16 by 7 (Use a calculator if needed)

16 / 7 = 2.3 (In estimation)

So, now you have ' -9 + 2.3 '

= -6.7

Find x so that the two points are on the line with the given slope (1,-1) and (x,7): undefined
Annette [7]

Value of x for which the two points are on the line with the given slope (1,-1) and (x,7): undefined is x=1 .

<u>Step-by-step explanation:</u>

Here we have to Find x so that the two points are on the line with the given slope (1,-1) and (x,7): undefined . Let's find out:

We know that for any two points given as P(x_1,y_1),Q(x_2,Y_2)  slope of line is determined by :

⇒ Slope = \frac{y_2-y_1}{x_2-x_1}

According to question we have two points as  P(1,-1),Q(x,7) ∴

⇒ Slope = \frac{y_2-y_1}{x_2-x_1}

⇒ Slope = \frac{7-(-1)}{x-1}

But slope is undefined which is only possible when denominator is zero i.e.

⇒ x-1=0

⇒ x=1

Therefore , Value of x for which the two points are on the line with the given slope (1,-1) and (x,7): undefined is x=1 .

Please help me!! Iv been stuck!
Sloan [31]

Answer:

7

Step-by-step explanation:

Because the leftmost triangle is a 45-45-90 isosceles right triangle, a = b =\frac{7\sqrt2}{\sqrt2} = 7\\

The rightmost triangle is a 30-60-90 triangle, and the side lengths are in the proportion 1:\sqrt3:2 from shortest to longest. Therefore, c = 7\cdot\frac{\sqrt3}{1} = 7\sqrt{3} \implies \boxed{7}
