You would add them together if it’s on a number line bc u have to go 5 to get to 0 then another 13 so 13+5=18
Answer:
x = z/(6πy)
Step-by-step explanation:
Divide by the coefficient of x.
z/(6πy) = 6πxy/(6πy)
z/(6πy) = x
Answer:
a) (-4, 5)
b) (4, -5)
Step-by-step explanation:
Just reverse the signs or use desmos as a better example.
We set up the equation 580/4 = 725/x. Since we know these are proportional, we can cross-multiply and solve to get x = 5.
Answer:
30/169
Step-by-step explanation:
We need to know how many marbles in the bag
6 red marbles + 2 white marbles + 5 blue marbles = 13 marbles
P (red) = red / total = 6/13
We then put the marble bad so there are still 13 marbles in the bag
P(blue) = blue /total = 5/13
P (red then blue ) = P(red) *P(blue)
= 6/13 * 5/13 = 30/169
