Answer:
a. The 1's are heavier than the x's. There isn't a whole number on top of the x's.
b. The equation would be 2x<9 because the 9 is greater(heavier) than the 2x. To continue to solve you would divide 2 by both sides. That would turn into x<9/2.
Step-by-step explanation:
Needs to use reciprocals:
time*(1/6+1/14) = 1 pool,
time = 1/(1/6+1/14) = 84/20 = 21/5 = 4.2 hours
Both rectangles could be divided into 36 parts
Number = 125
Here, ∛125 = 5
so, in exponential form, it would be: 5³
So, your final answer is 5³
Hope this helps!
Answer: 25
Assuming the dotted line touches the middle of the base of the triangle,
Using Pythagoras Theorem,
(30/2)^2 + (20)^2 = x^2
x^2 = (15)^2 + 400
x^2 = 625
x = √625 or -(√625)
x = 25 or -25
But since x needs to be a positive value,
x = 25
