Answer:
1/3
Step-by-step explanation:
substitute x for 2 and so you have 4×2 which is 8 then +1=9
substitute y for 3 then swuare it which is 9
3×9 equals 27
divide 9 by 27 and you get a third
Let's convert them to decimals:
1/25 = 0.04
4% = 0.04
0.04 = 0.04
0.4 = 0.40.
So 0.4 is NOT equivalent to the other values.
Answer:
-10² = -100
Step-by-step explanation:
The error in the evaluation occurred when the negative base (which is -10) was squared altogether outside of the parenthesis. (-10²) still results in <u>-100</u>.
The only time that the result will produce a positive 100 is when you square -10 this way: (-10)² = 100 because the negative sign is included with the squaring of base through the parenthesis.
Hope this helps.
The difference of a number P and one and four tenths is more than nine and seventy-eight hundredths.
P - 1.4 > 9.78
Cd+e = 21
Cd + e - e = 21 - e
Cd = 21 - e
Cd/C = 21-e/C
d = 21-e/C.
