Jenna has 6 yards of string. she needs 15 inches to make a necklace. how many necklaces can she make?

she can make 14 necklaces

Step-by-step explanation:

1 yard=36 inches

36×6=216

216÷15=14

14 (14.4 if your allowed to make 2/5 of a necklace)

Step-by-step explanation:

First let's change the 6 yards of string to inches to make this easier.

Note: for every 1 yard it is equal to 36 inches

So let's multiply the length (6 yards) by 36 = 216 inches

We know that she needs 15 inches to make one necklace. So let's take our 216 inches and divide by 15.

216/15= 14.4

So Jenna can make about 14 necklaces.

sorry i dont know my friend

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
