<span>0.25 (16x + 12) + 2x = 33
4x+3+2x=33
subtract 3 from both sides
6x=30
divide
6x/6=30/6
x=5</span>

.25(16x + 12) + 2x = 33
The first step is to distribute the .25 to what's inside the parentheses! 
((16x*.25) +(12*.25)) + 2x = 33
Simplify...
4x + 3 +2x = 33
Add like terms...
6x + 3 = 33
Subtract three from both sides
6x + 3 - 3 = 33 - 3
Simplify
6x = 30
Divide each side by six
6x/6 = 30/6
Simplify
x = 5
That's your answer; x = 5! Hope this helped :)

Which equation describes the line that passes through the points (-4, 19) and (2, -1)
dangina [55]

Answer:

y=-5/2x+4

Step-by-step explanation:

find the slope by using y2-y1/x2-x1

-1-19/2-(-4)

simplify

-20/8

simplify

-5/2

use slope-intercept form, y=mx+b

since we know the slope, find b

plug in one of the ordered pairs into the equation

-1=(-5/2)(2)+b

simplify

-1= -10/2+b

simplify

-1=-5+b

add 5 to both sides

b=4

plug b into y=-5/2x+b

y=-5/2x+4

I'm so confused. Please help I tried the first time got 50 some thing then 33 then 20.25. How do I do this?
vazorg [7]

Answer:

Basically, you have to think: more bricks : more time

more workers : less time

2,400 bricks 6 workers takes 18 hours

You now have to solve for 4,500 blocks and 10 workers

4,500 / 2,400 = 1.875 (times greater)

10 / 6 = 1.666666666 (times less)

So, we get 18 hours, multiply it by 1.875 and divide it by 1.666666666

which equals 20.25 hours

So, it seems you were correct on your third try.

natima [27]

Answer:

6in

Step-by-step explanation:

Given data

Volume of the lockbox= 312 cubic inches

Height= 4in

Length= 13in

Width= ???

The expression for the volume of box is

V= L*W*H

substitute

312=13*W*4

312=52W

W= 312/52

W=6 in

Hence the width is 6in
