Answer:
8 x 10/11 equals 69. If you mean something else, let me know.
Step-by-step explanation:
If you need any help, ask Brainly. Have a nice day!
The total would be 180 degrees because angles on a straight line would always add up to 180.
(3x+31)+(2x-6)=180
5x+25=180
-25 -25
5x=155
/5 /5
x=31
Answer:216
Step-by-step explanation:
Answer:
2*(5x - 2) + 2*(3x+1) ; Perimeter = 62 centimeters
Step-by-step explanation:
2*(5x - 2) + 2*(3x+1) = 10x - 4 + 6x + 2
= 16x -2
If x = 4 , then Perimeter = 16*4 - 2 = 64 - 2 = 62 cm
Simple...
you have:
1.) x-3y when x=-4 and y=9
-->>> (plug it in)
-4-3(9)
-4-27
-31
2.) a-|b| when a=-7.6 and b=-8.9
-->>>(plug it in)
-7.6-|-8.9|
-16.5
3.) 3(8x-y) when x=-4 and y=9
-->>(plug it in)
3(8(-4)-9)
3(-32-9)
3(-41)
-123
4.)

when c=2 and d=



54
Thus, your answer.
