(1) Commutative property
(2) Distributive property/Definition of addition
(3) Compatibility with addition/Existence of additive inverse/Modulative property
(4) Compatibility with multiplication/Associative property/Definition of division/Existence of additive inverse/Commutative and modulative properties/Result
Step-by-step explanation:
We proceed to solve algebraically and explain each step:
1) GIven
2) Commutative property
3) Distributive property/Definition of addition
4) Definition of addition
5) Compatibility with addition
6) Existence of additive inverse/Modulative property
7) Compatibility with multiplication
8) Associative property/Definition of division/Existence of additive inverse/Commutative and modulative properties/Result
Hence, we have the following answers:
(1) Commutative property
(2) Distributive property/Definition of addition
(3) Compatibility with addition/Existence of additive inverse/Modulative property
(4) Compatibility with multiplication/Associative property/Definition of division/Existence of additive inverse/Commutative and modulative properties/Result
The value of x is 10
You do 3x-3 = 2x+13
Subtract 2x from both sides
x-3 = 13
add 3 to both sides
x=10
Hai!!! Your answer is both x=-10 and x=10

Answer:
$2505.80
Step-by-step explanation:
After the first exchange, the tourist has ...
$3000(12.90 R/$) = R38,700
After 7 days, she has ...
R38,700 -7(R900) = R32,400
After the second exchange, she has ...
R32,400 × ($1/R12.93) = $2505.80
She gets $2505.80 at the second exchange.
Answer:
0.6808
Step-by-step explanation:
First, find the standard deviation of the sample.
s = σ / √n
s = 3 / √49
s = 0.429
Next, find the z-score.
z = (x − μ) / s
z = (28.8 − 29) / 0.429
z = -0.467
Use a calculator or z-score table to find the probability.
Using a table:
P(x > -0.47) = 1 − 0.3192 = 0.6808
Using a calculator:
P(x > -0.467) = 0.6796
