Step-by-step explanation:
Answer : Option B
------------------------------
when x = -3 , check for y
------------------------------
3(-3) + 2y = 11
-9 + 2y = 11
2y = 11+9
2y = 20
y = 10
The coordinate is (-3, 10)
The answer is 2 7/12. To find the answer you first find the equal denominator of 1/2 and 3/4 which is 4 because if you multiply 2 by 2 it is 4, then you multiply the 1 (numerator) by 2 to get 2 which 1/2 is 2/4, then you add 2/4 and 3/4 which is 5/4 which is equal to 1 1/4. Then you make the denominator of 1 1/4 and 1 1/3 equal, the number that both can equal is 12. You multiply 1/4 by 3 and you get 3/12, then you multiply 1/3 by 4 to get 4/12. So now you can add 1 3/12 and 1 4/12 which is 2 7/12.
#21: (4•4) + (7•7)= (c•c)
16+49= (c•c)
65=(c•c)
_/65= c
#22: 22+90= 112
180-112= 68
68
#23: (3.5•3.5) + (4.7•4.7) = (c•c)
12.25 + 22.09= (c•c)
34.34= (c•c)
_/34.34= c
#24: 22+90= 112
180-112= 68
68
