You can do this by finding a number close to it, and then finding out how to do it.
For example with 63(square root sign), find out what is close to it.
7x7=49 while 8x8=64
Because of this, we now know that it is between 7 and 8 but is also really close to 8.
Our number could be 7.9
Hope this helped!!!
Answer:
the answer is 1.25 or 5/4
Answer:

Step-by-step explanation:
we have
50%, 2/25, 5, and 0.31
1) 50%
we know that

2) 2/25
Multiply by 4/4

3) 5
Multiply by 100/100

4) 0.31
Multiply by 100/100

Now all numbers have the same denominator
so

therefore


A:amount of money invested in the account with 3% simple interest
B: amount of money invested in the account with 4.5% simple interest
a+b=25000 ——>a=25000-b
0.03a+0.045b=900
30a+45b=900000
2a+3b=60000
2(25000-b)+3b=60000
50000-2b+3b=60000
B=10000
A=25000-10000=15000
Answer:
B
Step-by-step explanation:
RANGE are the Y values
