X is the unknown value.  The word "of" means to multiply.  40% in decimal form is 0.40. So "40% of a value" means "0.40x".  
20=0.40x
Divide both sides by 0.40:
x=50

What is the distance between points P(2,7) and Q(10,13)?
wolverine [178]

To calculate the distance between two points, we can use a formula that is a variation Pythagorean Theorem. Look:


\mathsf{d=\sqrt{(x_Q-x_P)^2+(y_Q-y_P)^2}}


"d" represents the distance and coordinates are expressed as follows: (x, y)


Let's go to the calculations.


\mathsf{d=\sqrt{(x_Q-x_P)^2+(y_Q-y_P)^2}}\\\\ \mathsf{d=\sqrt{(10-2)^2+(13-7)^2}}\\\\ \mathsf{d=\sqrt{(8)^2+(6)^2}}\\\\ \mathsf{d=\sqrt{64+36}}\\\\ \mathsf{d=\sqrt{100}}\\\\ \underline{\mathsf{d=10}}


The answer is 10 uc.

Enter the slop-intercept equation of the like that has slope -2 and y-intercept (0,7)
LenaWriter [7]

Answer: y= 2x + 7

Step-by-step explanation:

Slope intercept form = y= mx + b

You are given slope (m=2) and a point (0,7) so

7 = 2(0) + b

7 = b;

So your equation is y= 2x + 7
