Answer:
Step-by-step explanation:
Let the number of minutes in 6.1 hours be x. Remember that there are 60 minutes in one hour. Therefore,
If 60 minutes = 1 hour,
Then
x minutes = 6.1 hours
Cross multiplying, it becomes
x × 1 = 6.1 × 60 minutes
x = 6.1 × 60 minutes/1
Therefore, the correct ratio with which 6.1 hours would be multiplied is
60 minutes/1 hour
You can start by distributing the 5 to everything in the parenthesis.
5x-50=30-15x
Then get rid of your x values from one side, I chose to subtract 5x
-50 = 30 - 20x
Then subtract 30
-80=-20x
/-20
4=x
You can check by plugging your x into the equation to make sure it's right!
Answer:
5.83 inches
Step-by-step explanation:
The card is a rectangular shaped object, drawing a diagonal from one corner to the other, divides the rectangle into two right angled triangles with the diagonals as the hypothenuse.
Using Pythagoras theorem.
c^2 = a^2 + b^2
Given;
Side a = 3
Side b = 5
Substituting the given values;
c^2 = 3^2 + 5^2
c = √(9+25)
c = √34
c = 5.83 inches
Ok.graph the 2.3 and the 6.8 as regular decimals, draw a line, annd I dont know how to do the last part. :(
