The number is -9
Step-by-step explanation:
Let x be the number then according to given statement
Subtracting 10 from both sides
Subtracting x from both sides
Dividing both sides by 3
<u>Verification:</u>
The number is -9

We can use the distribution method for both sides:
9 (x+2) = 5 - 2( x - 1 )
9x + 18 = 5 -2x + 2
Move like terms to one side and combine:
9x + 2x = 5+2-18.
11x = -11
x = -1.
3 weeks = 21 days
Let Jerrad's vacation be X then Max's be 2X and Wesley's 4X
X+2X+4X=21
7X=21 devide by 7
X=3 so Jerrad had 3 days vacation
2*3= 6 Max had 6 days
4*3=12 Wesley had 12 days vacation
P-6=19; p=13
so you just plug the value of P into the problems P and solve the equation
(13) - 6 = 19
7=19
so...that's incorrect because 7 can't equal 19 making the problem No solution. if that's wrong then idk what they're teaching in math any more...
I believe this is Pythagorean theorem
The equation is
a^2+b^2+=c^2
In this case the equation would be
6^2+4^2=c^2
36+16=c^2
52=c^2
c=7.21110255093
