The correct answer is <span>1 and 1/2
Hope I helped</span>
Answer:
See below.
Step-by-step explanation:
14.
12.5/2.5 = 5
15.
(i) [(-75)/15]/5 = -5/5 = -1
(ii) 13 / [(-2) + 1] = 13 / (-1) = -13
16.
(i) 39 + (-24) - 15 = 0
36 + (-52) - (-36) = 20
Answer: <
(ii) (-10) - 4 = -14
(-10) - (-4) = -10 + 4 = -6
Answer: <
17.
He reads 1/4 book in 1 hour.
He reads 1 book in 4 hours.
In 2 1/6 hours he reads:
(2 1/6)/4 part of the book = (13/6) / 4 = 13/24 part of the book
(i) 2/5 / 1 1/2 = 2/5 / 3/2 = 2/5 * 2/3 = 4/15
(ii) 7/3 / 2 = 7/3 * 1/2 = 7/6
Well, her initial investment happened at day 0, namely x = 0, let's check,
Step-by-step explanation:
This problem bothers on the density of substances
Given data
Mass of substance m= 16kg
Volume of substance v = 2L
the equation that relates the volume. V. to the mass, m is the expression for density
ρ= mass/volume
Substituting our given data
ρ= 16/2= 8kg/L
Using the density calculated above we can get the volume liters, of 128kg of liquid
8= 128/v
v=128/8
v= 16L
The volume is 16L
The density of a substance is expressed as the mass per unit volume

6 or in interval notation [-9,6]
To find out what are the steps in solving the below inequality:
Given equation is 2x - 3 > 15
The absolute value function takes any term and transforms it to its non-negative form. Therefore, we must solve the term within the absolute value function for both its negative and positive equivalent.
−15≤2x-3≤15
First, subtract 3 from each segment of the system of equations to isolate the x term while keeping the system balanced:
−15−3≤2x-3−3≤15−3
−18≤2x-6≤12
−18≤2x-6≤12
Now, divide each segment of the system by 2 to solve for x while keeping the system balanced:

-9

or

on the horizontal axis.
The lines will be a solid line because the inequality operators contain "or equal to" clauses.
We will shade between the lines to show the interval:
Hence the steps to solve an inequality has been show
