Answer: Tyrone has 28 mystery novels.
Step-by-step explanation:
Divide 42 by 3 to get 1/3 of the books he has.
42/3 = 14
14 * 2 = 28
28 = 2/3 of his books
X +x²= 132
x +x²-132= 132-132
x²+x -132 = 0
(x-11) (x+12) = 0
x-11 = 0 X+12=0
x-11+11 = 0+11 X+12-12=0-12
x =11 x= -12
Check
x +x²= 132 x +x²= 132
-12 +-12²= 132 11 +11²= 132
-12 + 144 = 132 11+ 121=132
132= 132 132=132
Since the problem says positive the answer is (11,121)
I am not really sure what you mean by this question
Answer:
244.
Step-by-step explanation:
We have been given that Allie wants to subtract 341-97 mentally. First she adds 3 to 97 to get 100. We are asked to determine Allie's next step and the difference of both numbers.
Allie's next step would be add 3 to 341 because adding same quantity to both numbers will keep the ratio same.
After adding 3 to 341 Allie would get
.
Now, we will subtract 100 from 344 as:

Therefore, the difference of both numbers would be 244.
24 because the - cancel eachother out.
