Explain how an estimate helps you place the decimal point when multiplying 3.9 × 5.3
2 answers:
An estimate helps you because you round 3.9 to 4 and 5.3 to 5 so then you can give a rough estimation
Answer:

Step-by-step explanation:
To find : How an estimate helps you place the decimal point when multiplying
?
Solution :
Estimate the number 3.9 by rounding to ones,
As tenth place 9 >5 ones place round by 1.
So, 
Estimate the number 5.3 by rounding to ones,
As tenth place 3<5 ones place remain same.

Answer: The group wants to raise $1,200.
Step-by-step explanation:
We can use a proportion to solve.
part/whole = percent/100
If we insert the values:
276/x = 23/100
We can cross multiply.
276 x 100 = 27,600
27,600 / 23 = 1,200
$1,200 is the answer.
Slope = -5
y-intercept = 5
y = -5x + 5
