Answer: 17/2
Step-by-step explanation:
1- <u>Add</u> up the numbers.
2- Cut 2 below the second fraction with 2 cubed, then 2 will be squared.
3- Solve the potentiation (2 squared is equal to four, because 2 * 2 = 4)
4- And, finally, compute 9/2 + 4. It will give 17/2.
5 - 3 x
= 5 - 3 (-7)
= 5 + 21
= 26
1/2x + 42 = 4x
-1/2x -1/2x
------------------------
42 = 3.5x
/3.5 /3.5
------------------------
12 = x
the number is 12
explanation: 42 more than 1/2 of a number can be written as 1/2x + 42
four times a number can be written as 4x.
42 more than 1/2 of a number is equal to 4 times a number. So 1/2x + 42 = 4x.
