bromheads.tv: a. y=5

b. RS = 37 , ST =16 and also RT = 53 .

You are watching: Find the exact values of sin a and cos a. write fractions in lowest terms.

Step-by-action explanation:

Given: On number line we have,

RS = 7y + 2, ST = 2y +6, and also RT = 13y - 12.

a. Because its on number line so we have

RT = RS+ ST

i.e. 13y - 12 = (7y + 2) + ( 2y +6)

⇒ 13y - 12 = 7y + 2 + 2y +6

⇒ 13y-12 = 9y+8

⇒ 13y-9y = 8+ 12

⇒ 4y = 20

⇒ y= 5

b. Now , RS = 7(5) + 2 = 35+2= 37,

ST = 2y +6 = 2 (5)+6 = 10+6 =16,

and RT = 13y - 12 = 13 (5)-12 = 65-12 = 53.

Hence, RS = 37 , ST =16 and also RT = 53 .

Pls help i require this
Svetradugi <14.3K>

Hello from MrBillDoesMath!

bromheads.tv: 19/34

Discussion:

Recompose the equation as adheres to (by inserting parentheses)

1/2 + ( -1/5 + 1/5) + (-1/8 + 1/8) + (-1/11 + 1/11) + ( -1/14 + 1/14) + 1/17

Note that the terms in each parenthese include approximately 0. (e.g. -1/5 + 1/5 = 0). The amount becomes

1/2 + 0 + 0 + 0 + 0 + 1/17 =>

1/2 + 1/17 =>

17/34 + 2/34 = (17 + 2)/34 = 19/34

Thank you,

MrB

When cut into 16 equal slices, each slice is 1/16 of the pizza. Express just how a lot of the plzza 8 of these slices would be in deci
Anastasy <175>

bromheads.tv:

the bromheads.tv is 0.5, or about 50%

Step-by-action explanation:

If 8 slices are being take out of 16, divide the taken pieces by the full pieces, and also it would certainly be fifty percent or 0.5.

Hope this helps
