The fractions 2/18 and 1/9 are equivalent because the prior reduces to the latter. The first answer is correct, as instead of the four occurrences of the number two, Juan used the number two. The correct fraction should have been 4/18. The number of occurrences over the number of times the dice was rolled, not 2/18, the quantity over the number of rolls.
Hope this simplifies it,

Which graph represents this equation y-4=3(×+5)

lawyer [7]

Answer:

Look at image

Step-by-step explanation:

well y-4=3(x+5)

distribute the 3 to x and 5 --> y-4 = 3x+15

now add 4 to both sides --> y-4+4 = 3x + 15 +4

y= 3x + 19

Answer:

1) Sam's Club is better because the price for 10 cans at the village market would be $6.20 versus $4.70 from Sam's Club

2) 420 people with 210 per hour

3) It would be more beneficial to buy apples from the Quick Market considering the explanation below.

4) 396 quarts per hour and a daily rate of 792.

Step-by-step explanation:

1) $3.10 x 2 = $6.20

2) 70 x 6 = 420

so, 210 per hour

3) $1.05 divided by 3 is $0.35 per apple at the Quick Market

$2.55 divided by 5 is $0.51 per apple at the Stop and Save.

4) take 330 and divide by 10 to get the amount per hour which is 33 quarts per hour.

330 + 33 + 33 = 396 for 12 hours

396 x 2 = 792 for one day.

6|6-4x|=8x+4 Need help solving the equation. I need help checking the extraneous solutions too.

Vsevolod [243]

$6|6-4x|=8x+4\\\\Formula\ for\ absolute\ value\\\\
|a|=a,\ for\ a \geq 0\\ or\\|a|=-a,\ for\ a \ \ -4x \geq -6\ \ -->\ \ \ x \leq \frac{3}{2}\\\\
6(6-4x)=8x+4\\
36-24x=8x+4\ \ |subtract\ 4\\
32-24x=8x\ \ | add\ 24x\\
32=32x\ \ | divide\ by\ 32\\
x=1\ \ \ and\ 1 \leq \frac{3}{2}\\\\
II\\
for\ 6-4x \ \ -4x < -6\ \ -->\ \ \ x > \frac{3}{2}\\\\
6(-6+4x)=8x+4\\
-36+24x=8x+4\ \ | subtract4\\
-40+24x=8x\ \ \ | subtract\ 24x\\
-40=-16x\ \ | divide\ by\ -16$ $x=2,5\ \ and\ 2,5>\frac{3}{2}\\\\Solutions:\\
x\in \{1;2,5\}$

Does any one understand these questions explain if you can.

1) 136 is the circumference of a circle with what area? we know C=πd.
136=πd
136/π=d
d=43.290 so the radius is half that, or
r=21.645
taking area as our measure of size,
A=πr²
A=π•21.645²
A=1471.855. answer C is closest. difference is in how they and I rounded

2) c, e, and f
