16-2t=3/2t+9 solve for t
answer: t=2
steps:
16-2t = 3/2t+9

2 is 4/2
7 = 3/2t + 4/2t
7 = 7/2t
7/2t = 7
(2/7)7/2t=7(2/7)

How to use Algebra Properties?We want to multiply the linear expressions; -2n and ³/₄n.
The first step will be to express them with the multiplication sign to get and factorize;
-2n × ³/₄n
Now, since n is common to both terms, we will factorize it out to get;
n(-2 × ³/₄)
Now, that operation above is termed as a distributive property because we know that the algebra distributive property is;

Evaluate (10 – 4i) ÷ (5 + i)
Answer:
the answer would be 23/13 - 15/13i
Step-by-step explanation:
The result of the complex expression (10 – 4i) ÷ (5 + i) is [tex]\frac{23}{13} - i\frac{15}{13}[/tex] .
Given, complex expression (10 – 4i) ÷ (5 + i)
Complex roots: When the roots are complex in nature then they appear in complex conjugate pair.
Complex roots: a ± ib
Complex number pair : a ± ib
i = iota(imaginary number)
a = real part

Multiplicative
8/9 = 9/8
12/15 = 15/12
-6 = -1/6
10 = 1/10
Step-by-step explanation:
an additive inverse is a number you must add to another number to get 0
(think of it as the negative version of the number)
{but WHY? In math, you can imagine comparing numbers on a number line. If we are finding the opposite of a number, we want to find the same distance from 0, but on the opposite side of 0. So, 2 would be two to the right of 0, -2 would be two to the left of 0}
-2 + 2 = 0
18 - 18 = 0
-30 + 30 = 0
2/5 - 2/5 = 0
a multiplicative inverse is a number that you multiply by another number to get 1.
We are finding the "reciprocal" of a number; you are essentially flipping it as a fraction
(reciprocal of 2 = 1/2 {remember, 2 is the same thing as 2/1 } ; reciprocal of 1 / 8 = 8)
note: reciprocal is being used interchangeably with multiplicative inverse here
8/9 · 9/8 = 1
12/15 · 15/12 = 1
-6 · -1/6 = 1 {-6 = -6/1}

A car manufacturer has parked some new cars in 2 car parks.In the first car park there are 60 cars in the ratio 1 red car for every 2 blue cars and 3 silver cars.In the second car park there are 80 cars in the ratio 2 blue cars for every 3 red cars and 5 silver cars.
11. How many red cars are there altogether?
12.How many blue cars are there altogether?
13.How many silver cars are there together?
The total number of red cars is 34, the total number of blue cars is 36, and the total number of silver cars is 70.
How do we solve ratio problems?
The ratio problems can be solved as follows:
11. The total number of red cars can be calculated as follows:
Number of red car in the first car park = (1 / (1 + 2 + 3)) * 60 = 10
Number of red car in the second car park = (3 / (2 + 3 + 5)) * 80 = 24
Total number of red cars = 10 + 24 = 34
12. The total number of blue cars can be calculated as follows:
Number of blue car in the first car park = (2 / (1 + 2 + 3)) * 60 = 20
Number of blue car in the second car park = (2 / (2 + 3 + 5)) * 80 = 16
Total number of blue cars = 20 + 16 = 36
13. The total number of silver cars can be calculated as follows:
Number of silver car in the first car park = (3 / (1 + 2 + 3)) * 60 = 30
Number of silver car in the second car park = (5 / (2 + 3 + 5)) * 80 = 40
Total number of silver cars = 30 + 40 = 70

Subtraction property of equality
====================================================
Explanation:
Let's say we started with the equation a = b
Subtract c from both sides to get a-c = b-c
This is the subtraction property of equality
-----------------
Example:
x+5 = 12
x+5-5 = 12-5 ... using the subtraction property of equality
x+0 = 7
x = 7
------------------
For this current problem, we're subtracting 3 from both sides in the second step.
A very closely related property is the addition property of equality where we add the same thing to both sides.
Technically we could add -3 to both sides to get the same task done in the second step. But the subtraction property is more direct and straight-forward in my opinion.

Using the properties of integer exponents, match each expression with its equivalent expression.
From the power rules, the matching of each expression with its equivalent expression is:
[tex]5^{-3}=\frac{1}{125}[/tex]
[tex]-5^{-3}=-\frac{1}{125}[/tex]
[tex](-5^{-3})^{-1}=-125[/tex]
[tex](-5^{-3})^{0}=1[/tex]
Power RulesThere are different power rules, see some them:
1. Negative exponent. For this rule when you have a negative exponent, you need to invert the number, i.e, the power base is converted to the denominator. After that, you should solve the power with a positive exponent. See the examples:
[tex]4^{-3}=\frac{1}{4^3} =\frac{1}{64} \\ \\ {\frac{4}{6} }^{-2}=( {\frac{6}{4} })^{2}=\frac{36}{16}[/tex]
2. Power. For this rule, you should repeat the base and multiply the exponents. See the example, [tex](2^{2})^3=2^6=64[/tex].
3. Zero Exponent. When you have an exponent equals to zero, the result must be 1. See the example, [tex]2^0=1[/tex].
From this for your question, you have:
[tex]5^{-3}=\frac{1}{5^3}=\frac{1}{125}[/tex][tex]-5^{-3}=-\frac{1}{5^3}=-\frac{1}{125}[/tex][tex](-5^{-3})^{-1}=(-5)^{3}=-125[/tex][tex](-5^{-3})^{0}=(-5)^{0}=1[/tex]Read more about power rules here:

The graph below have the same shape.what is the equation of the blue graph?
Answer:
g(x) = (x - 5)²
Step-by-step explanation:
This is an example of the transformation of functions.
In this example, we see the graph f(x) has been moved 5 in the positive direction on the x-axis.
Due to the fact that we are working with the x-axis, our transformation will be placed inside the bracket, and it will do the opposite of what we expect.
This means that our transformation will be set out in this format:
[tex]g(x) = f(x-5)[/tex]
We know that:
[tex]f(x) = x^2[/tex]
Therefore,
[tex]g(x) = f(x-5) = (x-5)^2[/tex]
So, [tex]g(x) = (x-5)^2[/tex].

The probability that the coin lands on tails and the dice lands on an even number is 0.3455
How to determine the probability?Let A represents a biased coin lands on heads and B represents a biased dice lands on an even number
So, we have:
P(A) = 0.47
P(B) = 13/20
The required probability is:
P(A' and B) = P(A) * P(B)
This gives
P('A and B) = (1 - 0.47) * 13/20
