Answer:
25.5
Step-by-step explanation:
2( -21+9x)=2x+18
-42+18x=2x+18
+42 +42
18x=2x+60
-2x -2x
16x=60
60/16=3.75
x=3.75
GH=2x+18
2(3.75)+18
7.5+18=25.5
GH=25.5
Answer: there were 854 buttons in bag a
Step-by-step explanation:
4342 = a + b + c
b = a + 18
c = 3b
4342 = a + (a + 18) + 3(a + 18)
4342 = a + a + 18 + 3a + 54
4342 = 5a + 72
-72 -72
4270 = 5a
/5 /5
854 = a
