The correct answer is B 4:1
When you divide 6/2 and 24/2 you get 4/1
X = 3 * 40 / 15 = 8
The answer is 8
Answer:
90
Step-by-step explanation:
8*5 = 40
40 + 5 = 45
1/2 x = 45
x = 90
7-6a=6-7a
+7a on both sides gives you
7-X= 6
Subtract 7 from both sides
-X= -1
Add the negative sign in front of the x to the -1
X= --1
This will end up to be
x= 1
