Answer:
25x + 35(2x) = 380
25x + 70x = 380
95x = 380 so
x = 4
then i think that mean it might be 8 then im not completly sure
Answer:
X = -20
Step-by-step explanation:
X = -2(6+4)
^ add 6 and 4 together first because they are in parentheses
-2(10)
^ this parenthesis means you want to multiply -2 and 10
because 2 x 10 = 20
that must mean -2 x 10 = -20
therefore, the value of X is -20
X= -20
Answer:
Step-by-step explanation:
A bag contains 8 red marbles, 3 blue marbles and 7 green marbles.
Total = 18 marbles.
Probability of drawing three red marbles = probability of drawing one red without replacement + probab of drawing another without reeplacement + probab of drawing a third without replacement.
Probability of drawing three red marbles = 8/18 + 7/17 + 6/16 = 0.4444 + 0.4118 + 0.3750 = 1.2312.
The Pythagorean theorem tells you that for legs a and b, and hypotenuse c this relationship holds:
c² = a² + b²
It can be useful to make a couple of rearrangements of this relation.
c = √(a² +b²)
a = √(c² -b²)
1. c = √(10² + 8²) = √164 = 2√41
2. a = √(26² - 10²) = √576 = 24
_____
It doesn't matter which leg you call "a" and which one you call "b", unless they are specifically marked on the triangle. Then use the marks you are given.
It is a cubic function that is down up (the direction of the ends) and has roots at (figure out the roots either 1/2/3)
