Convert 7.6 cm/yr (centimeters per year) to km/Myr (kilometer per million years.

1 answer:

4 0

You'd do the same as in brainly.com/question/2700999

lemme hmmm redo the fractions... and as I said, you flip them around as needed
$\cfrac{7.6cm}{1y}\cdot \cfrac{1m}{100cm}\cdot \cfrac{1km}{1000m}\cdot \cfrac{1,000,000y}{1myr}$

notice, we flipped them some, so the unit ends either above or below
in order to cancel the one on the left

Solve -44-7k=12+k answer quick please

nirvana33 [79]

Answer:

k = -7

Step-by-step explanation:

Solve for k:

-7 k - 44 = k + 12

Subtract k from both sides:

(-7 k - k) - 44 = (k - k) + 12

-7 k - k = -8 k:

-8 k - 44 = (k - k) + 12

k - k = 0:

-8 k - 44 = 12

Add 44 to both sides:

(44 - 44) - 8 k = 44 + 12

44 - 44 = 0:

-8 k = 12 + 44

12 + 44 = 56:

-8 k = 56

Divide both sides of -8 k = 56 by -8:

(-8 k)/(-8) = 56/(-8)

(-8)/(-8) = 1:

k = 56/(-8)

The gcd of 56 and -8 is 8, so 56/(-8) = (8×7)/(8 (-1)) = 8/8×7/(-1) = 7/(-1):

k = 7/(-1)

Multiply numerator and denominator of 7/(-1) by -1:

Answer: k = -7

blsea [12.9K]

To do this you need 94 inches of braid.
<span>94 inches = 2.61 yards

You would need to buy 3 yards so:
$0.60 </span>× 3 = $1.80.

Since you bought 3 yards that would cost $1.80.
