Lets use a rule of three, simple, with direct proportion to find that number, we write the data of the problem as a rule of three like so taking into account that we are looking the 100% of an unknown number:
80% ----> 76
100% ----> x
x = (100)(76)/80
x = 95
therefore, we find that 76 is the 80% of 95
Lets put the problem all together first
1) p^2+mn
2^2+0(-1)
Now we start
2x2=4
0x-1=0
4+0=4
Your answer should be 4:)
2) m+np^2
0+-1(2)^2
2x2=4
-1x4=-4
0+-4=-4
Your answer should be -4:)
Answer:
the answer to this question is 92
Step-by-step explanation:
(7+3-1) +(-8+91)
=7+2+-8+91
=92
