Solve the system of equations:
25−x=−4y
3x−2y=30

(7, -4.5)

Step-by-step explanation:

25−x=−4y  ---> x=25+4y

3x−2y=30

use x to substitute into the second equation

3 (25+4y)-2y = 30

75+12y-2y=30

75+10y=30

10y=-45

y=-4.5

3x-2(-4.5)=30

3x+9=30

3x=21

x=7

check:

25-7=-4*-4.5

18=18 (yes)

3*7-2*-4.5=30

21+9=30

30=30 (yes)

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

black/brown

step-by-step explanation:

well, you see here, jamal was born to 2 parents, his mother who he lives with and his father who left at a young age and who happens to be younger than him. he stole cookies because he has to steal food due to the fact that he spends his government poverty checks on pot and women.
