Answer:
57
Step-by-step explanation:
Let c represent the number of children ($1.75 each) and a represent the number of adults ( $2.00 each).
We know that there were 340 people total, so c + a = 340. This implies that a = 340 - c
We also know that $1.75 c + $2.00 a = $609.25
By substituting a with 340 -c we have $1.75 c + $2.00 (340 -c) = $609.25
Use the distributive property to obtain $1.75 c + $680 - $2.00 c = $609.25
Subtract $680 from both sides and combine like terms to get - $0.25 c = -
$70.75
Now, divide both sides by -$0.25 to get c = 283, the number of children.
The number of adults is 340 - c or 340 - 283 = 57
Answer:
the answer is 0.012, terminating
Step-by-step explanation:
move the decimal place three places to the left
since it is not repeating it is terminating
C is 50 cents because 2 dollars divided by 4 is 50
Here's an example number:
123.456
The place values are, from greatest to least:
The 1 is in the <em /><em>hundreds</em> place
The 2 is in the <em /><em>tens</em> place
The 3 is in the <em>ones</em> place
The 4 is in the <em>tenths</em> place
The 5 is in the <em>hundredths </em>place
If you have some number like 9.40 with no decimal point, shifting it will change the value. Moving the decimal one place to the right multiplies the value by ten. (94)
Moving it one place to the rigt divides it by ten. (0.94)
Here's our list from least to greatest:
94.0
9.40
0.94
0.094
