Hello there!
2(x + 5) = 3x + 1
You want to start with the distribution property
(2)(x) + (2)(5) = 3x + 1
2x + 10 = 3x + 1
2x - 3x = 1 - 10
-x = -9
Multiply by -1 to remove the negative sign
x = 9
3y - 4 = 6 - 2y
3y + 2y = 6 + 4
5y = 10
y = 10/5
As always, it is my pleasure to help student like you.
45 per 3 hours! :) hope this is good
First, convert 54 into a fraction.
It would be 54/1.
Now multiply 7/9 and 54/1 across; multiply the numerator by the numerator and the denominator by the denominator.
7 x 54 = 378
9 x 1 = 9
We get 378/9.
9 can go into 378 exactly 42 times.
So, 7/9 x 54 = 42.
There’s probably something wrong with the registration, you should contact your teacher or counselor to help.
