8 ÷ (2/3)
Divide 2/3 first, because it's in the parenthesis.
Divide 8 by the product of 2/3 = 12.
Answer:
Step-by-step explanation:
We just multiply the values on the edges like we are finding the area of a square, L * L = area.
4x * 5x = 20x^2
4x * 8 = 32x
3 * 8 = 24
3 * 5x = 15x
Next add the answers together
20x^2 + 47x + 24
Answer:
No.
standard deviation kind of works like absolute value. think of it that way. absolute value is just distance from zero and standard deviation is just distance from the mean.
Let first number is x
second number be y
one number is four less than a second number: x=y-4
Three times the first is 6 more than 6 times the second: 3x=6y+6
substitute x=y-4 in 3x=6y+6
3x =6y+6
3(y-4)=6y+6
3y-12=6y+6
3y-6y=6+12
-3y=18
y=-6
substitute y=-6 in x=y-4
x=-6-4=-10
so first number is -10
second number is -6
