Answer:
10 times 8= 80 then 80 times 6 =480
Step-by-step explanation:
Assuming there 6-2 isn't in brackets, otherwise, it would be a tad more complex:
6 -2(x-4) = 22
6 -2x + 8 = 22
14 - 2x = 22
-2x = 8
-x = 4
x = -4
Answer:
Step-by-step explanation: Plug -4 in for each "y" in the equation. Then solve: -4 squared is 16, 5 times -4 is -20, so you have 16-20+7 which equals 3.
It will take the train 14 hours to reach miles,
I got this by dividing 35 by 490.
3n/2-n/4=7n+4/12
12 (3n/2-n/4=7n+4/12) factored in 12 to both sides to get rid of fractions
12 (3n/2)-12 (n/4)=12 (7n)+12 (4/12) distributive power
36/2n-12/4n=84n+48/12
18n-3n=84n+4 simplified
15n=84n+4
15n-84n=84n-84n+4 addition property
-69n=4
-69/-69n=-4/69 division property
n=-4/69
Solution : n=-4/69
