Let's use a for number of days when he shot 50 shots and b for number of days when he shot 100 shots.
We have:
a + b = 20
We also know that he shot total of 1250 shots:
50a + 100 b = 1250
We have two equations. We can solve them for a and b. Let's rearange first equation for a:
a= 20 - b
We insert this into second equation:
50 * (20 - b ) + 100b = 1250
1000 - 50b + 100b = 1250
50b = 250
b = 5
a = 20 - 5
a = 15
Mark shot 100 shots on 5 days.
f(x) + g(x) =
4x + 3
3x^2 + 2x - 4

3x^ +6x -1
Answer: 3x^ +6x -1
Either you typed something wrong in the problem or the answer
Step-by-step explanation:
ok whats the question tell
Answer:
Neither.
Step-by-step explanation:
You can only add exponents when multiple, or subtract when dividing.
Also, 2x^3 and 2x^2 are two different terms, not like terms, so cannot subtract the two.
Answer:
distance is 14.04
Step-by-step explanation:
the distance between 2 points is the Hypotenuse of the right angled triangle of the x and y coordinate differences.
we use Pythagoras
c² = a² + b²
c = the Hypotenuse (the side of the triangle opposite to the 90 degree angle).
the x difference
-8 - 6 = -14
the y difference
-2 - -1 = -1
c² = -14² + -1² = 196 + 1 = 197
c = sqrt(197) = 14.04
