So the first thing we need to do is multiply 3*-5, since order of operations dictates it (PEMDAS)
Now, whenever we see a minus negative number, we can think of it as adding a positive number
Now we just add them together
23 is the answer
If you find the least common denominator, that is 143. Then, you convert 2/13=22/143 and 1/11=13/143. Next, subtract 22/143-13/143=9/143 which is B
Please learn your fractions :/ they’ll be useful for the future, trust me. If you need further help to understand, idk if there is a PM feature here but if there is feel free. But I have answered 3 fraction questions for you within this hour and it’s under the high school level category??? Thank you and have a nice night.
D.
you do change in y divided by change in x
(5-1)/(1-0) = (4)/1=4
Answer:
(13 + or - (sign) square root(37)) / 6
Step-by-step explanation:
First search up the quadratic formula which is
x = (- b + or - square root(b^2 - 4ac)) / 2a
and to find a, b, and c you need this formula
ax^2 + bx + c = 0 (btw this is the safest solution to finding your answer with a number in-front of a quadratic equation.)
Math:
a = 3, b = -13, c = 11
b = -13, because of the x on the other end of the equation as the equation above "ax^2 + bx + c = 0" you need the zero to proceed to this next step.
Side Note: You only take the number and not the variable, variables are x, y, w, z, or etc.
(- (- 13) + or - square root((-13)^2 - 4(3)(11) ) ) / 2 * 3
13 + or - square root(37) / 6
Answer: The mean is 3780
Step-by-step explanation:
Mean is found by adding all values and dividing the sum by how many values were added.
4250+4019+3895+3739+3401+3376=22680
22680/6=3780
