Step-by-step explanation:
if its $2 per packet and he is buying 3 do 2x3 which is 6 then 10-6 which is $4
Y=1/9(-1)+4
Explanation:
X=-1 and y=8
Answer:
y = 2.4
Step-by-step explanation:
first distribute into the parenthesis' -
2(y-3) = 1.2 -y
2y - 6 = 1.2 - y
+y +y
3y -6 = 1.2
+6 +6
3y = 7.2
/3 /3
y = 2.4

Answer:
B. 39°, 106°, 43°
Step-by-step explanation:
The sum of angle measures in a triangle is 180°. Then the sum of angle expressions will be 180.
(3x +1) +(11x -4) +(5x -7) = 180
19x -10 = 180 . . . . . collect terms
19x = 190 . . . . . . . . add 10
x = 10 . . . . . . . . . . . divide by 19
__
Then the three angle measures are ...
- 3·10 +1 = 31
- 11·10 -4 = 106
- 5·10 -7 = 43
The appropriate choice is ...
B. 31°, 106°, 43°
