Chloe needs to swim a total of 9 miles this week. So far this week , she swam 5 5/8 miles. Use the equation 5 5/8 + m =9 to find

pshichka [43]

Alright, so all we have to do here is solve the equation!

5 5/8 + m = 9

m = 9 - 5 5/8

Now is the tricky part - doing the subtraction! Let's change 9 to 8 8/8 (which is still equal to 9).

m = 8 8/8 - 5 5/8

Then we can subtract fairly easily!

m = (8 - 5) + (8/8 - 5/8)

m = 3 3/8 miles

Hope this helps!! :)

Formula of finding the distance : absolute value (x2-x1)^2 + (y2-y1)^2
Distance from house to school : (Under Absolute value) (x2-x1)^2 + (y2-y1)^2
( -4 - (-4) )^2 + (10 - 3 )^2 = 0 + 49 = Radical 49 = 7
Distance from house to grocery store : (using the same method) you get = Radical 1200 = 60
Distance from house to community center : (using the same method) =
Radical 85
Yes, the distance from her house to grocery store is greater then to community center

The drama club is planning a field

Inessa [10]

Answer:

$\frac{2}{3}s+8=48$ .

Step-by-step explanation:

If we indicate the amount of students in the drama club as"s", we know that $\frac{2}{3}s$ is attending to the trip.
We also know that there are will be 8 teachers in the trip as well.
If the total amount of persons that will go on the trip reachs 48, which is the sum of 8 teachers and the $\frac{2}{3}s$ of the students: $\frac{2}{3}s+8=48$ .

Then, the equation that describes the situation is $\frac{2}{3}s+8=48$ . If we subtract 8 from both sides of the equation, and then we have $\frac{2}{3}s=40$ , which means that s=60.
