Answer:
x=27
Step-by-step explanation:
180-2x-40+180-3x+180-x-50+180-4x = 360
360-2x-40-3x+360-x-50-4x= 360
360-10x-90= 0
10x= 270
x= 27

Answer:
what is 1 6/10+5 2/10
=16/10 + 52/10 =
<u>16+52 = 68</u>
10 10
6/8-24/8
=6/8-20/8
<u>6-20 = 14</u>
8 8
6 6/10- 4 4/10
=<u>66-44 = 22</u>
10 10
Step-by-step explanation:
1/ if the fraction is mixed number example 2 1/7, it will be 2x7+1 and that will be 15 over 7
2/and if the bottom number example: 2 1/7, 7 is the bottom number and if 2 1/3 (3 is the bottom number) then see what the bottom number have in common example: 7-x1=7
7x2=14
7x3=21
3x1=3
3x2=6
3x3=9
3x4=12
3x5=15
3x6=18
3x7=21
so 21 is 7 and 3 have in common so the bottom number which is now 21 will divide 7 and got 3 and 3 will go on the top number 1 and 21 divide 3 which is 7 will go on the top number 1 and you continue to add your sum or subtract understand or not
Answer:
49.1
Step-by-step explanation:
Add all the numbers up together and divide by how many there are so....
35 + 61 + 63 + 69 + 49 + 46 + 52 + 32 + 34 + 50 = 491
491 divided by 10 is 49.1

X^2 + 9y^2 = 25
x^2/5^2 + (3y)^2/5^2 = 1
This represent an equation of an ellipse with cente at the origin, the horizontal major axis running from -5 to 5 and vertical minor axis running from -5/3 to 5/3
The third graph is the correct answer.
