Not sure what you were looking for see attached Answer:
-5(x + 3) + 3(x - 1/3) = -24
Distributive property
-5x - 15 + 3x - 1 = -24
+5x
-15 + 3x - 1 = -24 + 5x
+24
9 + 3x - 1 = 5x
-3x
9 - 1 = 2x
Combine 9 and -1
8 = 2x
Divide by 2
x = 4
The correct answer for the question that is being presented above is this one: "xy / pm = 8." The equation that models the situation is this xy <span>/ pm = 8
</span>
<span>If x varies directly with the product of p and m and inversely with y:
</span><span>x = pm/y
</span>2 = 0.5*2 / 4
8 = 1
Then,
xy / pm = 8

Answer:
B. -3/2 +1/5
Step-by-step explanation:
The distributive property lets you multiply each of the inside terms by the outside factor.
(-1/2)(3 -2/5) = (-1/2)(3) +(-1/2)(-2/5)
= -3/2 +1/5
Hello :
<span>√(4x+13) = 2x-1......(1)
note : if ( a=b) so (a² = b²)
if : (</span>√(4x+13) )²= (2x-1)² so : 4x+13 = 4x²-4x+1
4x²-8x-12 = 0
x²-2x-3 = 0
(x+1)(x-3) = 0
x+1 = 0 or x-3=0
x= -1 or x=3
if : x= -1 : <span>√(4(-1)+13) = 2(-1)-1
</span>√9 =-3 but √9 =3
3 = -3 impossible ( -1 is not solution of equation (1)
if : x = 3 : √(4(3)+13) = 2(3)-1
5 = 5 ( right) conclusion : one solution : 3
