azamat4 years ago
4 0

Answer:

Value of z = 7

Value of y = 30  

Step-by-step explanation:

We are given the following equations in the question:

y = 9 + 3z\\y = 65 -5z

We have to solve the given equation for y and z.

Equating the two equations we get,

y = 9 + 3z\\y = 65 -5z\\9 + 3z = 65-5z\\3z + 5z = 65-9\\8z = 56\\\\z = 7\\y = 9+3(7) = 30

Value of z = 7

Value of y = 30

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.

Answer:1=70 2=65 3=95

Step-by-step explanation:

Angles in a triangle add up to 180°

180-45=135-65=70

1=70°

Angles on a straight line add up to 180°

180-45=135-70=65

2=65°

Angles in a triangle add up to 180°

180-65=115-20=95

3=95°
