-13 is 4 less than a number n

n - 4 = -13

Think of it like this.  Do you know what 4 less than a number n is?  Say n=5.  What's 4 less than 5?  That's 1.  What's 4 less than, say 7?  3.  We can write an expression: n-4.

So, if -13 is 4 less than n, or n-4, we have an equation: n-4 = -13 .  Are you familiar with negative numbers?  Well, what's 1-2?  That's -1.  Why?  Well, that's equal to 1-(1+1), which is equal to 1-1-1.  1-1=0, so this simplifies to 0-1.  Can you get any lower than 0?  Yes: using negatives!  0-1 equals 0 + -1.  Just like 0+1=1, 0 + -1 = -1.

Anyway, now we know about negative numbers.  Just think of -13 as 13 less than 0.  So we have n-4 = -13.  This could be your expression, if that's all you need.

Now, to solve, we need to find n, so we need to isolate it by adding 4 (the inverse operation) to both sides.  n-4+4 = -13+4.  n-4+4 equals n, but what's -13 + 4?  Well, if you're 13 below 0, but then you add another 4, then...you're 9 below 0, or -9!  So, n = -9.

Answer: n-4 = -13 OR n = -9

How much money would produce $70 as simple interest at 3.5% per<br> annum?
yKpoI14uk [10]

Answer:

$2000

Step-by-step explanation:

Simple Interest = $70

Rate = 3.5%

Time = 1

Principal = ?

Simple Interest = (Principal × Rate × Time)/100

Principal = (Simple Interest × 100)/(Rate × Time)

Principal = (70 × 100)/(3.5 × 1)

Principal = 7000/3.5

Principal = 14000/7

Principal = 2000

Help I Need Help Asap!
Leni [432]

Answer:

40° and 140° (with x = -10)

Step-by-step explanation:

Since the angles are supplementary (when added, equal 180°), you can add the two angles together to get (-18x)°. 180/-18 = -10 for x. Fill in -10 for x in both expressions. (-14 • -10)= 140° and (-4 • -10)- 40°. 140+40=180

Does the graph above have an Hamiltonian circuit, Hamiltonian path, or neither? Paths and Circuits Help
Hatshy [7]

a. Only a Hamiltonian path

One such path is

1 → 2 → 0 → 4 → 3

which satisfies the requirement that each vertex is visited exactly once.

There is no Hamiltonian circuit, however, since it is impossible for any Hamiltonian path on this graph to visit vertex 0 exactly once.
