Answer:

The angles are supplementary. X = 31

Step-by-step explanation:

The angles sum to equal 180 degrees, menaing they are supplementary. Add the degrees of each side 3x + 25 + 2x = 180 and solve for x. X should equal 31.

Sophia uses 18 beads to make a necklace. Three sixths of the beads are purple. How many beads are purple?

tatuchka [14]

Answer:

9 beads are purple

Step-by-step explanation:

we know that

To find out how many beads are purple, multiply the total beads by the fraction of the beads that are purple

$18(\frac{3}{6})=9\ beads$

therefore

9 beads are purple

Another way to solve the problem is convert the fraction in percentage

we have

$\frac{3}{6}=\frac{1}{2}=0.50*100=50\%$

If the total are 18 beads

50% is 9 beads

therefore

9 beads are purple

I need help as fast as possible

aivan3 [116]

Answer:

36°

Step-by-step explanation:

Given,

Measurement of <3 = 2x+8

Measurement of <4 = 6x+12

Since both are supplementary,

Therefore,

<3 + <4. = 180° [linear pair]

=> 2x + 8 + 6x + 12 = 180

=> 2x + 6x + 8 + 12 = 180

=> 8x + 20 = 180

=> 8x = 180 - 20 = 160

$= > x = \frac{160}{8}$

=> x = 20

Now as we have got the value of x,

According to the question measurement of <4 is,

<4 = 6×4 + 12 = 24 + 12 = 36° (Ans)
