Answer:
x=27.8
Step-by-step explanation:
first, you need to find y. 2y-5=65. 65+5 is 60 and you are left with 2y=70. to get the 2 off of the y you divide everything by 2. 70/2 is 35 therefor y=35. Now you plug that into the other equation (2x+y) and get 2x+35 which is equal to segment 90.6 so 2x+35=90.6. subtract 35 on both sides and you have 2x=55.6. To get the 2 off the x, we divide everything by 2. all of that divided by 2 is x=27.8
1) 12 out of 14 = 85% Win Rate
2) Now you have to figure out what is 85% of 21 so you have to plug in what you have ? out of 21 = .85
3) Multiply 21 x .85
4) Answer is They will win 18 out of 21 games
Answer:
You just need to find the length of LM and NM and then find the area of semi-circles using the formula πr²÷2
0, 3, -2, 8. You go up 8 rungs and you were halfway there so 16.
Answer:
36°, 63°, 81°
Step-by-step explanation:
Let 4x = measure of angle 1
7x = measure of angle 2
9x = measure of angle 3
The sum of the measures of the angles of a triangle = 180
So 4x + 7x + 9x = 180
20x = 180
x = 9
4x = 36 = measure of angle 1
7x = 63 = measure of angle 2
9x = 81 = measure of angle 3
Check: 36 + 63 + 81 = 180
