16-2t=5t+9
Answer: yes it is t={1}
PREMISES
16–2t=5t+9
CALCULATIONS
16–2t=5t+9
(16–9)-(2t-2t)=5t+2t+(9–9)
7–0=7t+0
7t=7
7t/7=7/7
t=1/1
t=

PROOF
If t=1, then the equations
16–2t=5t+9
16–2(1)=5(1)+9
16–2=5+9 and
14=14 prove the root (zero) t=1 of the statement 16–2t=5t+9

A woman bought 210 oranges for GH¢65.00. she sold all of them at 3 for ¢20.00. how much profit did she make?
Answer:
She made a profit of 1,335 cedis
Step-by-step explanation:
Here, we want to calculate the profit made
Profit is selling price - cost price
Her cost price is 65 credits
For her selling price;
she sells 3 for 20 cedis
So the price she sold 210 will be;
(210 * 20)/3 = 1,400 cedis
So the profit made is;
1,400-65 = 1,335 cedis

10 to the power of 4 as a decimal
Answer:
You treat it as 10^4 (the small number is the number of zeros. Therefore the answer is 10000. Or of you meant 10^-4. Its the same concept, just reversed. So the answer in this case is 0.0004.
Cheers! :)
10 to the power of 4 is equal to 10,000.
To calculate 10 to the power of 4 as a decimal, you need to raise the base number (10) to the exponent (4).
Here are the steps to compute it:
Step 1: Start with the base number, which is 10.
Step 2: Multiply the base number (10) by itself 4 times, since the exponent is 4. The calculation looks like this:
10 x 10 x 10 x 10 = 10,000
Step 3: The result of multiplying 10 by itself 4 times is 10,000.
So, 10 to the power of 4 (10⁴) is equal to 10,000.
Hence 10 to the power of 4 is equal to 10,000.

Find the domain and range of the function
Answer:
domain: (-∞ , ∞)
range: (-∞, 2]
Step-by-step explanation:
the domain is the set of values of what the x value can be. This function is parabolic and upside down, it can have a range of x values from - infinity to positive infinity. The function is most likely y=-x^2 +2
range is the output (y values) the function can possibly have. the max is 2 and includes 2 so we use bracket for that. The smallest y value can reach towards negative infinity.

Brandy only has $23 in cash to spend on drinks, and the concession stand charges $3.75
for a drink. If x represents the number of drinks purchased, and y is the amount of money
spent on drinks, what is the range in this situation?
Answer:
{0, 3.75, 7.5, 11.25, 15, 18.75, 22.5}
Step-by-step explanation:
Since the values in this function cannot go on infinitely this is a discrete funciton.
Its basically asking how much he can spend on drinks with 23$ if they are each 3.75$, this means that he can buy at most 6 drinks. Imagine a disctrete graph with a point on every value he spends per drink, (0,0) (1 , 3.75) (2 , 7.5) etc.
As our bright fellow shadow188 has stated, y is the range or the output so you list the possible outputs for the range in bracets.
I hope you found this helpful, ik its a little late.
The required range will be $3.75 ≤ y ≤ $23 for the function.
Given that,
Brandy only has $23 in cash to spend on drinks, and the concession stand charges $3.75 for a drink.
x represents the number of drinks purchased, and y is the amount of money spent on drinks, what is the range in this situation is to be determined.
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
Let the x be the cost of the drink and y be the total amount of money spent,
Since there are concession stand charges of $3.75 also.
So the minimum charge will be $3.75 whether bought the drink or not, and Brandy has $23 to spend on drinks so the maximum will be $23.
So, the range can be given as $3.75 ≤ y ≤ $23.
Thus, the required range will be $3.75 ≤ y ≤ $23 for the function.

Jesse took out a $14,000 car loan for 5 years at a 7.2% interest rate. Find Jesse's total payment amount for this loan.
Answer:
16,712.38
Step-by-step explanation:
Periodic interest rate 7.2%/12 = 0.6%
First find the monthly payment
M = $14,000 * 0.006(1 +0.006)^60/(1+0.006)^60-1 = 278.54
The total payment is $278.54 * 60= $16,712.38
Jesse's total payment amount for this loan is $16,712.38
What is Compound interest?Compound interest is a method of calculating the interest charge. In other words, it is the addition of interest on interest.
Compound Interest =P(1+r/n)^rt
We are given that Jesse took out a $14,000 car loan for 5 years at a 7.2% interest rate.
Periodic interest rate = 7.2%/12
= 0.6%
First we need to find the monthly payment
M = $14,000 x 0.006(1 +0.006)^60/(1+0.006)^60-1
M = 278.54
The total payment is
$278.54 x 60= $16,712.38
Hence, Jesse's total payment amount for this loan is $16,712.38

Step-by-step explanation:
so, -4/4 and 1/5 are both already fractions.
160% as a decimal would be 1.6. 1.6 as a fraction would be 8/5.
-4/4 is just -1
-1+1/5+8/5
