Answer:
10x>5x+100
Step-by-step explanation:
it says expression not equations so its < , >,
The profit would be on one side and the expenses on the other
No negatives
so it would be 5 times X (the amount of shirts) plus the base fee of $100
and they plan on selling it for 10$ each so (10x) is the profit
X = number of shirts
just fill out why it is 3
Answer:hi
Step-by-step explanation:hi
Because, in reverse it's basically asking what is 12 minus 5. So, 12 minus 5 is 3!

A manager of the credit department for an oil company would like to determine whether the mean monthly balance of credit card holders is equal to $75. An auditor selects a random sample of 100 accounts and finds that the mean owed is $83.40 with a sample standard deviation of $23.65. If you were to conduct a test to determine whether the auditor should conclude that there is evidence that the mean balance is different from $75, which test would you use? a) Z-test of a population mean b) Z-test of a population proportion c) t-test of population mean d) t-test of a population proportion
Answer:
c) t-test of population mean
Explanation:
The t-test statistic is used in hypothesis testing. Here we would use a one sample t test to test our hypothesis. The one sample t test measures the statistical difference between the hypothesized mean and the sample mean. In a one sample t test or single sample t test, a test variable is measured against a test value.
Example we compare our test variable to the hypothesized mean value $75 above.
The t test is used instead of z score when standard deviation is unknown.
Using the t test, we either accept or reject the null hypothesis given alternative hypothesis.

For the function f(x)=3x-4 find f(2)
Hi there!
[tex]\large\boxed{f(2) = 2}[/tex]
Evaluate f(x) at x = 2 by substituting 2 for x:
f(x) = 3x - 4
f(2) = 3(2) - 4
f(2) = 6 - 4
f(2) = 2

What is the value of n in the equation below 9n-24=4n+6
Answer:
6 (I believe so)
Step-by-step explanation:
9n-24=4n+6
9n=4n+30
5n=30
n=6
Answer:
n=6
Step-by-step explanation:
9n - 24 = 4n + 6
-4n -4n
5n - 24 = 6
+24 +24
5n = 30
divide both sides by 5
n = 6

Whats the percent of 550% of 22
Answer:

Convert 550% into a decimal by moving the decimal point 2 times to the left. 5.5. Then multiply 5.5 x 22 to get 550% of 22.
The sales tax on a $750 computer at T&C Computers is $75. What is the sales tax rate? BTW
ANSWER IS 10%
Answer:
10%
Step-by-step explanation:
Price of computer = $750
Amount of sales tax = $75
Sales tax rate = Amount of sales tax / Price of computer × 100
= $75 / $750 × 100
= 0.1 × 100
= 10%
Sales tax rate = 10%
Sales tax rate = 10% of selling price
2 pens in each pack of black pens 5 pens in each pack of red pens 6 pens in each pack of green pens On Monday number of packs sold of black, red and green pens = 7 : 3 : 4 A total of 212 were sold.
Answer:
The number of green pens sold is 96.
Step-by-step explanation:
Note: This question is not complete. The complete question is therefore provided before answering the question as follows:
A shop sells packs of black pens, packs of red pens and packs of green pens. There are:
2 pens in each pack of black pens
5 pens in each pack of red pens
6 pens in each pack of green pens
On Monday, number of packs of black pens sold : number of packs of red pens sold : number of packs of green pens sold = 7:3:4
A total of 212 pens were sold.
Work out the number of green pens sold.
The explanation of the answer is now given as follows:
Since the ratio is given in packs of pens, we have to first convert it to number of pens based on the number of pens in each pack. Therefore, we have:
7:3:4 is converted to (7 * 2) : (3 * 5) : (4 * 6) = 14 : 15 : 24
Based the new ratio, we have:
Weight of contribution of the green pens to the total number of pens sold = 24 / (14 + 15 + 24) = 24 / 53 = 0.452830188679245
The number of green pens sold can now be calculated as follows:
Number of green pens sold = Total pens sold * Weight of contribution of the green pens to the total number of pens sold = 212 * 0.452830188679245 = 96
Therefore, the number of green pens sold is 96.

Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
n = 5m
n = 2/3m - 13
Step 2: Solve for m
Substitution
Substitute in n: 5m = 2/3m - 13Subtract 2/3m on both sides: 13/3m = -13Divide 11/3 on both sides: m = -3Step 3: Solve for n
Define equation: n = 5mSubstitute in m: n = 5(-3)Multiply: n = -15Answer:
Step-by-step explanation:
5m = 2/3m - 13
15m = 2m - 39
13m = -39
m = -3
n = 5(-3)
n = -15

richard and teo have a combined age of 42 richard is 12 years older than twos age how old are richard and teo
Answer:
teo= 15 years old
richard= 27 years old
Step-by-step explanation:
richard=r
teo=t
r + t=42
t + 12= r
u can use substitution here
(t+12) + t=42
2t + 12= 42
2t=30
t= 15
to find r, you just do 15 + 12= 27
to check you can do 27 + 15= 42
The age of Richard and Teo will be 27 years and 15 years, respectively.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
Richard and Teo are 42 years old. Richard is 12 years older than Teo.
Let x be the age of Richard and y be the age of Teo. Then the equation is given as,
x + y = 42 ...1
x = y + 12 ...2
From equations 1 and 2, then we have
y + 12 + y = 42
2y = 30
y = 15
Then the value of the variable 'x' is given as,
x = 15 + 12
x = 27
The age of Richard and Teo will be 27 years and 15 years, respectively.

Calculate the average rate of change for the given graph from x = 3 to x = 5 and select the correct answer below.
Answer:
Average rate of change between x = 3 to x = 5 is 0.
Step-by-step explanation:
Given quadratic function s passing through two points (3, 0) and (5, 0).
Average rate of change of a function between x = a and x = b is given by,
Average rate of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]
From the graph attached,
Average rate of change between x = 3 to x = 5 will be,
= [tex]\frac{f(5)-f(3)}{5-3}[/tex]
= [tex]\frac{0-0}{5-3}[/tex]
= 0
Therefore, average rate of change between x = 3 to x = 5 is 0.
Answer: The average rate of change for the given graph from x=3 to x=5 is 0

Keep that Michelle went out To dinner. The total cost of the meal, including the tip, came out to $53.70. It's a combined tip came out to $9.60 and each friend spent an equal amount, how much did each friend pay not including the tip?
The question is incomplete:
Keith and Michelle went out to dinner. The total cost of the meal, including the tip, came to $53.70. If the combined tip came out to $9.60, and each friend spent an equal amount, how much did each friend pay not including the tip?
Answer:
Each friend paid $22.05 without including the tip.
Step-by-step explanation:
Since you know the total cost of the meal including the tip and the value of the combined tip, you can subtract the amount of the tip from the total cost and divide the result by 2 as they spent an equal amount:
$53.70-$9.60=$44.1
$44.1/2=$22.05
According to this, the answer is that each friend paid $22.05 without including the tip.
