Rachel and her friends are making necklaces out of beads and straws. They plan to use 12 beads and 5 straws for each necklace. T
bagirrra123 [75]

Answer:

225 necklaces.

Step-by-step explanation:

Assuming that they have the necessary amount of straws to match the beads then we can use the following simple equation to solve this problem.

t = b/12  ... where t is the total amount of necklaces and b is the number of beads you have

t = 2700 / 12

225 necklaces.

For 225 necklaces you would also need 1125 straws since each necklace requires 5 straws to be fully made. Therefore if you have this amount you should not run into any problems.

Write the equation of a line that is perpendicular to the given line and that passes through the given point. y=2/3x+9 m (–6, 5)
Marina86 [1]
<h2>Question :</h2>

<em>Write the equation of a line that is perpendicular to the given line and that passes through the given point. y=2/3x+9 m (–6, 5)</em>

<h2>Answer :</h2>

<em>y = -3/2x - 4 </em>

<h2>Explanation :</h2>

y = mx + c

*m = gradien

•>looking for gradients

y=2/3x+9

m1 = 2/3

m2 = -3/2

•>line equation (-6,5)

y - y1 = m(x - x1)

y - 5 = -3/2(x - (-6))

y - 5 = -3/2(x + 6)

y - 5 = -3/2 - 9

y = -3/2x - 9 + 5

y = -3/2x - 4

Simplify 7m - 11n - n + 5m.
goblinko [34]

Answer:

The simplified form of the given expression is 12(m -n).

Step-by-step explanation:

The given expression is

7m - 11n - n + 5m

We need to simplify the given expression.

Rearrange the terms according to the variables.

7m+5m - 11n - n

On combining like terms, we get

(7m+5m)+( - 11n - n)

On simplification, we get

(12m)+( -12n)

12m -12n

Taking GCF common.

12(m -n)

Therefore the simplified form of the given expression is 12(m -n).
