In the equation x-y = 5 subtract x from both sides , and then divide by -y. so at the ned you will get what y equals to and plug that into your equation
2x-2y = 10.

Let me know if this is helpful :)

You have to get x alone and then do the rest of the steps

If the slope and a point of a line are given, then the equation of the line can be written in point-slope form. True False

True, just plug the slope and points into the formula: y - y1 = m(x - x1), where y1 is the y number, m is the slope, and x1 is the x number.

Answer:

0.1527

Step-by-step explanation:

Standard Deviation = √p × q/n

Reynolds: 63%

Bachmann: 37%

n = 100

Standard Deviation = √0.63 × 0.37/100

= √(0.02331)

= 0.1526761278

≈ 0.1527

muhammad, a shipping and receiving clerk uses 1 yard, 2 feet and 4 inches Of twine to wrap each carton he packs. he has to pack

antiseptic1488 [7]

Answer:

He will need 51 yards, 1 foot and 8 inches twine to wrap 29 cartons.

Step-by-step explanation:

Muhammad uses 1 yard, 2 feet and 4 inches of twine to wrap each carton he packs.

We know that, 1 yard = 36 inches and 1 foot = 12 inches.

So, 1 yard, 2 feet and 4 inches $=[(1*36)+(2*12)+4]inches = 64$ inches.

That means, he uses 64 inches of twine to wrap each carton.

He has to pack 29 cartons today. So, the total length of the twine he will need $=(64*29) inches= 1856$ inches.

Now....

1856 inches

$=\frac{1856}{36} yards \\ \\= 51 \frac{5}{9} yards \\ \\= 51 yards+(\frac{5}{9}*36)inches \\ \\= 51 yards, 20 inches \\ \\= 51 yards, (12+8)inches \\ \\=51 yards, 1 foot, 8 inches.$
