X/0.4 = 10x/4
21/9÷31/6 = 21•6/31•9
so solving the equation gives
X=84/465
Answer:
therefore there is only one solution
Step-by-step explanation:
try solving it step by step
6x - 4 = x + 6 add 4 to both sides
6x = x + 10 subtract x from both sides
5x = 10 divide both sides by 5
x = 2
Answer:
8
Step-by-step explanation:
the outer shape
then the tree triangles in the first part of the big triangle
then the first layer of the triangle itself
then 3 more triangle starting from top to bottom
Step-by-step explanation:
When you have a ratio, you put one number as the numerator and than one number as the denominator.
so it would be (12/34)=(x/68)
In this example I made the ratio you are comparing it to have 68 dollars, so when you solve for the amount of quarters you need it should be 24, since all of the numbers in this example are just being doubled.
To solve for x, you multiply 68 on both sides of the equation, 68×(12/34)=x
24=x
So this proves that this is how ratios, are used. It also does not matter what number you place on the numerator or denominator.
