Answer:
3:5, 12:20
Step-by-step explanation:
A ratio is basically just a fraction. Therefore, 6:10 is just 6/10, or 3/5, or 3:5. It's the same thing as a fraction, just with a colon.
Thus, all you need is two equivalent fractions to 6/10. Examples are 3/5, 12/20, 30/50, etc. After you find the fractions, you just need to put them back into ratio form, so 3:5, 12:20, 30:50, etc.

Step-by-step explanation:
If a quadratic equation has the following form:
then its discriminant D is defined as
In our given quadratic equation, a = 4, b = -2 and c = 6, so its discriminant is
Note: The value of the discriminant D will determine the characteristics of the roots of the quadratic equation according to the following rules:
there will be 2 real roots
there will be 1 real root
there will be 2 imaginary roots
Hence our given quadratic equation will not have any real roots but only imaginary ones.
The solution to the equation is x = 20.
<u>Step-by-step explanation</u>:
The equation is 2( x – 5) = 9 – 3 x + 6 + 8 + 3 x + 7
2x - 10 = 30
2x = 30+10
2x = 40
x = 40/2
x = 20
Answer:
Equation: y=1.5x+4 Will total $10 after 4 hours
Step-by-step explanation:
Format: y=mx+b
y is total cost
m is per hour
b is starting cost
Equation: y=1.5x+4
After 4 hours, it will be $10 because:
10=1.5x+4
subtract 4 both sides
6=1.5x
divide 6 by 1.5
4=x
Hence the 4 hours answer
Am not quite sure but it’s 17
Hope this helped
