Answer:
y = 10
x = 25
Step-by-step explanation:
From the U theorem the sum of these two angles 120+2x+y = 180
same goes for the bottom part too:
2x-y+140 = 180 now add two equations up
120+2x+y + 2x-y+140 = 180 + 180 add like terms (-y will eliminate +y)
4x + 260 = 360 subtract 260 from both sides
4x = 100 divide both sides by 4
x = 25 since the sum of 2x-y+140 = 180 we can find the value of y by replacing x with 25
2*25 - y + 140 = 180
50 - y + 140 = 180 add like terms
190 - y = 180 subtract 190 from both sides
-y = -10 and y = 10
Answer:
The answer would be 0,0754716981
8%
4 ÷ 50 is 0.08 x 100 is 8%
Answer: 45 and 46
Step-by-step explanation: let the first integer be x and the second x + 1
i.e x + x + 1 = 91
2x = 90
x = 45
the second is 45+1 = 46
Answer:
4c - 4d
Step-by-step explanation:
3c - 9d + 7c + 5d
4c - 9d +5d
4c - 4d
Hope this helps!
