2y-4=y+18
+4 +4
2y=y+24
-y -y
y=24
Hi there
All you have to do is replace a by 2 and b by 7 and solve it.
4(2)^4 - 2(7^2) + 40
4(16)-2(49)+40
64 - 98 + 40
-34 + 40
= 6
Answer : A
Good luck!
You would have to do 336 divided by 12 and that equals 28. So your answer would be 28
Answer:
y = 2x or x = 1/2y or if you would like numerical values then x = 3, y = 6 and z=4
Step-by-step explanation:
x : y = 1 : 2
y : z = 3 : 2
If x : y = 1 : 2 then we know that 1y = 2x ∴ y = 2x or x = 1/2y
If y : z = 3 : 2 then we know that 3z = 2y ∴ z = 2/3y
Hi!
9[6+6(8-4)]
First solve in the parentheses
9[6+6·4]
Now multiply in the brackets.
9[6+24]
Now add in the brackets
9·30
Multiply
270
The answer is 270
Hope this helps! :)
