4 0

Answer:

1.

-3|2x+6|=-12
|2x+6|=4

2x+6=4

2x+6=-4

x1=-5, x2=-1

2.

|x-2|+10=12
|x-2|=12-10
|x-2|=2

x-2=2

x-2=-2

x1=0, x2=4

You are going to draw two candy bars from a large bag containing 28 snickers bars and 5 twix bars. what is the probability that

amm1812

Find the probability of drawing 1 snicker first then the probability of drawing another snicker after that, then multiply them together. For the first choice, the probability of drawing a Snickers is 28/33 (snickers/total candy bars). For the second choice, there are only 32 candy bars left, 27 of which are Snickers. So that probability is 27/32, so...
The probability of BOTH things happening is their product 756/1,056 which is 63:88

18 is 75 percent of what number

dimulka [17.4K]

18 is 75% of x.

$75\%= \frac{75}{100}=\frac{3 \times 25}{4 \times 25}=\frac{3}{4} \\ \\
\frac{3}{4}x=18 \\
x=18 \times \frac{4}{3} \\
x=6 \times 4\\
x=24
$

18 is 75% of 24.

A school is building a rectangular soccer field that has an area of 6000 square yards. The soccer field must be 40 yards longer

kogti [31]

Area is 6000 yd2

LW = 6000

field must be 40 yards longer than its width

L = W + 40

Replace L with W+40 in 1st equation to solve for Width

(W+40)(W) = 6000

W2 + 40W - 6000 = 0

This is a quadratic but is factorable

Factors of -6000 that add to 40 are (100)(-60)

(W+100)(W-60) = 0

W = -100 or W = 60

Since the width will not be negative discard -100

The width is 60 yards

Length is W+40 = 100 yards
