First, we can do distributive property.
-3(n + 8) = 15
-3 x n = -3n, -3 x 8 = -24
So we have, -3n + -24 = 15
Minus -24 on both sides of the equal sign.
-3n + -24 - -24 = 15 - -24
-3n = 39
Divide 3 on both sides.
-3n/-3 = 39/-3
n = -13
Hope i helped!! :D
Let's solve your equation step-by-step.
7(x+2)=6(x+5)
Step 1: Simplify both sides of the equation.
7(x+2)=6(x+5)
(7)(x)+(7)(2)=(6)(x)+(6)(5)(Distribute)
7x+14=6x+30
Step 2: Subtract 6x from both sides.
7x+14−6x=6x+30−6x
x+14=30
Step 3: Subtract 14 from both sides.
x+14−14=30−14
x=16

Answer:
$13,708 dollars lost total
Step-by-step explanation:
10458+3250=13708
Write each equation in y = mx + b form so that you can compare the slopes.
Perpendicular slopes are opposite reciprocals.
For example: 2/3 and - 3/2; 4/5 and -5/4; 1/2 and -2
I. y = -3x + 2 m = -3
II. y = 3/2 x + 1/2 m = 3/2
III. y = - 1/3x + 1/3 m = -1/3
IV. y = 1/3x + 9 m = 1/3 (I assuming this one had a typo in it since there is no equal sign.)
LETTER B is the answer I & IV
