Answer:
[tex]t= \frac12C +3[/tex]
Step-by-step explanation:
Let's first write the data you have in an equation form:
[tex]C= -6 + 2t[/tex]. When t = 0, at dawn, you get -6°C so we're good. But you've ben asked the inverse relationship, so let's solve for t instead.
[tex]-6+2t = C\\2t = C+6\\t= \frac12(C+6)\\t= \frac12C +3[/tex]
Last two are both viable solution, only difference is in form. I do prefer the last option since it makes it easiest at a glance to answer to the question "at what time there's a temperature of 0°C?"

The owner of a small store buys coats for $40.00 each .she sells the coats for $7200 each. What percent of the purchase price is the sale price? The owner increased the price by the same percent
Answer:
Step-by-step explanation:
0056 because 1% is 72 so you know it’s going to have to be less then 72. So to get your percent you divide 40 by 7200 so 40/7200. This will get you .00555556 which I rounded to .0056
Here is an inequality: 7x+6/2<3x+2
Answer:
A and B
Step-by-step explanation:
times 2 both sides
7x+6<=6x+4
minus 6x both sides
x+6<=4
minus 6 both sides
x<=-2
becuase x is less or equal than -2 it must be x=-3 and x=-2

1)Solve 3x+2= 5
A. Model 3 2 x+ = 5.
B. Perform the step to have the variables (circles) alone on one side.
C. Write the resulting step.
D. Divide the variables (circles) and numbers (squares) into equal groups.
E. Show the value of one group.
The value of x in the equation, 3x + 2 = 5 is 1.
In order to solve this equation: 3x + 2 = 5, take the following steps:
Combine similar terms together:
3x = 5 - 2
Add the similar terms together
3x = 3
Divide both sides of the equation by 3 in order to make x the subject f the formula
3x / 3 = 3 /3
x = 1

The new donut shop sold 210 donuts in the first hour. At this same rate, how many donuts would the shop sell in 90 minutes? Solve the word problem using the unit rate.
Hey this is me again ....
[tex] \frac{210}{60} = \frac{x}{90} \\ [/tex]
[tex] \frac{21}{6} = \frac{x}{90} \\ [/tex]
Multiply both sides by 90
[tex]90 \times \frac{21}{6} = 90 \times \frac{x}{90} \\ [/tex]
[tex]15 \times 21 = x[/tex]
[tex]x = 315[/tex]
So that shop would sell 315 donuts in 90 minutes

55.99 dollars gift with 18% coupon and 7.25% sales tax. What is the final cost?
Answer:
I think it is $91.89.
Step-by-step explanation:
1. Take the number and add sales tax by multiplying 0.0725 ( since that is what the percentage is in a decimal form). Then add that to the original and you have what it would be plus sales tax: $60.05.
2. Then you would need to multiply by 0.18. You would get 10.809
3. Next, subtract the 10.809 from $60.05 and the answer is $49.24.

Step-by-step explanation:
Kolby decided he wanted to go to the amusement park. The amusement park charges $8.00 for entry and $1.40 for each ride.
Part A Write an expression to represent this scenario where r represents the number of rides.
Part B Create and solve an equation to determine how many possible rides Deniss can ride if his parents gave him $26.00Show your work.
Answer:
He pays $8.00 regardless and $1.40 for each ride. When we see for each, we typically want to multiply.
A. $8.00 + $1.40 * r
If his parents gave him $26.00, then that is the most Kolby can spend.
$8 + $1.40 * r = $26
Subtracting 8 from both sides:
$1.40 * r = $18
Dividing both sides by 1.40:
r = 12.86
B. Since you can't ride part of a ride, Kolby can only ride 12 rides.
Step-by-step explanation:
Answer:
An expression to represent this would be 1.40x+8.00= R
1.40x+8=26
-8 -8
1.40x=18
/1.40 /1.40
x=11 total rides
If you had $26.00 you would first spend $8.00 on the entry leaving you with $18.00. Then you would divide the $18 by $1.40 for each ride to get 12.8... It doesn't make sense to go on a fraction of a ride so you just round down to 11 rides

f(x) = 3 V x - 15. Find the inverse of f(x).
O A F-1(x) = 23 - 15
O B. f-() = (x - 15)
O c. f-1(2) = 23 + 15
D. f- (c) = (x + 15)
Step-by-step explanation:
f(x) = ³√x -15
y = ³√x - 15
Finding inverse,
x = ³√y - 15
x³ = y -15
y = x³ + 15
f-¹(x) = x³ + 15

andre is solving the inequality 14x+3 is less than or equal to 8x+3.he first solves a related equation
14x+3=8x+3 this seems strange to Andre. He thinks he probably
14x=8x made a mistake.What was his mistake?
8=14
Answer:
14x+3=8x+3
14x+3 -3 = 8x+3 -3
Cancels out the 3
14x = 8x
14x - 8x = 8x -8x
Cancels out the 8x
14x = 0
x = 0
Step-by-step explanation:
Andre should have collected the like terms in order to have all the variables x on one side before taking the difference.
Inequality expressionGiven the inequality expression solved by andre expressed as:
14x + 3 ≤ 8x + 3
Simplify to have:
14x - 8x ≤ 3-3
6x ≤ 0
x ≤ 0
Hence andre should have collected the like terms in order to have all the variables x on one side before taking the difference.

Step-by-step explanation:
Let x be minutes.
Toatl costs for a call are:
A: 35 + 3x
B: 45 + 2x
When will A = B?
35 + 3x = 45 + 2x
