Okay so -6 + Y = 0
Y = his total score on the first day
so you can do 0- (-6)= Y
answer Y= 6
first day he got a score if 6
Answer:
the answer to your question is 30/7
Step-by-step explanation:
multiply by two first
-2x - 26 +9x = 4
then solve like terms
7x - 26 =4
then add 26 to both sides
7x - 26 +26 = 4+26
7x = 30
X= 30/7
First you convert both values into the same unit, either decimal or fraction. After you've done that you divide the number of minutes by itself and do the same for centimeters. At tye end, your steps should look like this on paper:
1) 3/2 divided by 3/2
2) 5.83 divided by 3/2
3) 3.8866666667 cm per minute
An equation can have 2 real roots if the discriminant is 4.
The standard equation of a unit circle is
x²+y²=1
So, if we want a radius of 4, we need to square it.
so we have x²+y²=16
