Answer:
3 cups of milk
Step-by-step explanation:
4/4 is 1 cup.
Step-by-step explanation:
5/8 × 6/8= 30/8 => this is the wrong one
it should be 5/8 × 6/8= 30/64.
9/10×3/10= 27/100 => this is the true one
Answer:
The equivalent expressions are;
9x + 9
and
9(x + 1)
Step-by-step explanation:
Mathematically, we should understand that an equilateral triangle has all of its sides equal
So if one side is 3x+ 3, the other sides too measures same
Therefore, the length of the rope represents the perimeter of the triangle
This is obtainable by adding all the side lengths together
This will be;
3x + 3 + 3x + 3 + 3x + 3 = 9x + 9
This is also same as 9(x + 1)
Answer:
2/5m - 1/5
Step-by-step explanation:
distribute the 2 to every term in ()
2(1/5m-2/5) = 2/5m - 4/5
now you have 2/5m -4/5 +3/5
combine like terms variables with variables, non- variables with non-variables. -4/5 + 3/5 = 1/5
2/5m - 1/5
The way we approach a problem like this is by using a technique called "collecting like terms".
This means that we want to put all of the values with an "x" on one side and all of the normal numbers on the other. For this particular problem we can do this as follows:
5x - 6 = x + 12
Now move the (- 6) to the right side of the equation by adding 6 to both sides:
=> 5x = x + 12 + 6
Now move the (x) to the left side of the equation by subtracting (x) from both sides:
=> 5x - x = 12 + 6
Now perform the simple arithmetic on both sides:
=> 4x = 18
Now remove the 4 from in front of the (x) by multiplying the whole equation by (1/4)
=> x = 18/4
Therefore to make your open sentence true, x must equal 18/4, or to simplify, 9/2, or as a decimal, 4.5. I hope this helped, and remember to try and understand not just the answer, but the maths involved in getting to the answer too :))
