B. 1 hour, he takes the exact amount of time that he types.
Answer:
(x) = 4
Step-by-step explanation:
3/4 (x) + 4 = 7
3/4 (4) + 4 = 7
0.75 (4) + 4 = 7
3 + 4 = 7
7 = 7
N= - 31 over 19
alternative form
n= -1 12 over19 , n ~ - 1.63158
Exponents inside the parentheses are done first
eg. 5 + (25- 2) = ?
You would do the numbers inside first
25-2=23 to get 5 + 23 = 28
:)
Im gonna guess on this but add 7 and 8 you get 15 and add 10 and 8 you get 18 and if thats not the answer simplify 15/18 hope i helped a little
