I would check my math but 4/3 = 1.3 x 18= 24 divided by 2 for radius would be 12x12=144 x pie or 3.14 would be 452.16
I’m not sure about number 1 but the answer for number 2 is
-4 1/2, -4.2, -4, ,0, 4
9514 1404 393
Answer:
Step-by-step explanation:
Consecutive interior angles are supplementary.
(x -20)° +(4x +15)° = 180°
5x = 185 . . . . . . . . . . . . . . divide by °, add 5
x = 37 . . . . . . . . . . . . divide by 5
__
74° +(5y -4)° = 180°
5y = 110 . . . . . . . . . . . divide by °, subtract 70
y = 22 . . . . . . . . . . divide by 5
We can to make the method of substitution.
Look:
3x + 15y = 35
Isolating 3x
15y = 35 - 3x
Dividing both the sides by 15
y = 35/15 - 3x/15
Simpliting:
y = 7/3 - x/5
Now let's equate this expression with the other
7/3 - x/5 = - x/5 + 7/3
0 = 0
Oh noOo!
There is solution infinatly to this question!
Because, the two equation are the same.
Hope this helps!
