Answer:

Step 1: Distribute $-2$ to $5x$ and $8$

Step 2: Subtract from both sides of the equation $6x$

Step 3: Add to both sides of the equation $16$

Step 4: Divide both sides of the equation by $-16$

Step-by-step explanation:

Step 1: Apply the Distributive Property. Then you must distribute $-2$ to $5x$ and $8$

Then:

$-2(5x+8)=14+6x\\\\-10x-16=14+6x$

Step 2: You must apply the Subtraction property of Equality and subtract $6x$ from both sides of the equation. Then:

$-10x-16-6x=14+6x-6x\\\\-16x-16=14$

Step 3: You must apply the Addition property of Equality and add $16$ to both sides of the equation. Then:

$-16x-16+16=14+16\\\\-16x=30$

Step 4: You must apply the Division property of Equality and divide both sides by $-16$ . Then:

$\frac{-16x}{-16}=\frac{30}{-16}\\\\x=\frac{30}{-16}\\\\x=-\frac{15}{8}$

Find the distance between (2,7) and (-6,-2)

stepladder [879]

Answer: $\sqrt{145}$

Step-by-step explanation:

1. use the distance formula!

$distance = \sqrt{(x_{2} - x_{1})^{2} +{(y_{2} - y_{1})}^2$

2. then using the distance formula with (2, 7) and (-6, -2) you get...

$distance= \sqrt{2 -(-6)^2 +(7 - (-2)^2}$

$distance= \sqrt{8^2 +9^2}$

$distance= \sqrt{64 +81}$

$distance= \sqrt{145}$

$\sqrt{145}$ is the simplest radical form

there are 124 students in the band. there are 12 more boys than girls in the band. how many boys and how many girls are in the b

kvv77 [185]

B = g + 12
g + b = 124
Replace the b in the second equation with
g+ 12

g+ g+12=124
2g + 12 = 124
Subtract 12 from both sides
2g = 112
Divide by 2
g = 56

b= 56 + 12
b= 68
