Answer:The answer is A
Step-by-step explanation:1.add up all data values to get the sum 2.count the number of values in your data set 3.divide the sum by the count
First set up the ratio 2/5 = 10/x where <em>x</em> is the number of girls.
Now, we can use cross-products to find the missing value.
So we have (2)(x) = (5)(10).
Simplifying, we have 2x = 50.
Dividing both sides by 2, we find that x = 25.
So there are 25 girls in the class if there are 10 boys.
The slope needs to be the same to be parallel So anything with the same slope and a different y intercept
For example y=-2x+ 10
Answer:
the first one
Step-by-step explanation:
because 4/6=2/3
2/3=6/9
so 4/6=6/9
$140 ÷ 18 = $7.7777
rounded = $7.78 per square foot
NOT SURE WHAT YOUR QUESTION WAS EXACTLY SO GAVE YOU SOME OPTIONS
or $140 for 18ft² = $140 for 324ft
or $140 ÷ 324ft = $0.43 per foot
