The absolute value of a number is the distance the number is from zero on the number line. Only one number is 0 units from 0. It is zero. For all other distances, there are always two numbers. Example: The two numbers a distance of 1 unit from zero are -1 and 1. Example: The two numbers a distance of 4.5 units from zero are -4.5 and 4.5.

In your case, the two numbers a distance of 1.75 units from zero are -1.75 and 1.75. Find -1.75 between -1.5 and -2 and place a dot there. Find 1.75 between 1.5 and 2 and place a dot there.

hichkok12 [17]

Answer:

1200 students at the school

Step-by-step explanation:

Let x be the total number of students at the school

50% ride the bus

600 students ride the bus

x*50% = 600

Changing to decimal form

.50x = 600

Divide each side by .5

.50x/.5 = 600/.5

x =1200

Answer:

x = -7

Step-by-step explanation:

The whole line is 12

the whole line is also x + 14 and x + 12

so make them equal:

x+14 + x +12 = 12

2x + 26 = 12 now subtract 26 from both sides

2x = - 14 now divide both sides by 2

x = -7

Rob notices that 55 percent of the people leaving the supermarket chhose plastic bags instead of paper bags. out of 600 people,

Temka [501]

To solve this answer, you are trying to find 55% of 600, because that is the number of people who chose plastic bag.

55% can be re-written as 55/100 OR 0.55 since percentages are always out of 100.

So, we do 0.55*600, which gives us 330. 330 people carry plastic bags.

Simple Interest Rate Formula: $\displaystyle A = P(1 + r)^t$

P is principle amount
r is rate
t is time (in years)

Step-by-step explanation:

Step 1: Define

Identify variables

P = 7300

r = 3% = 0.03

t = 10

Step 2: Solve for A

Substitute in variables [Simple Interest Rate Formula]: $\displaystyle A = 7300(1 + 0.03)^{10}$
(Parenthesis) Add: $\displaystyle A = 7300(1.03)^{10}$
Evaluate exponents: $\displaystyle A = 7300(1.34392)$
Multiply: $\displaystyle A = 9810.59$
