NEED HELP ASAP
Alan used the expression StartFraction 5 over 9 EndFraction (F minus 32), where F is a temperature in degrees Fahrenheit, to convert a temperature from Fahrenheit to Celsius. He evaluated the expression as shown below and found that 45 degrees Fahrenheit was equivalent to –7 degrees Celsius.

StartFraction 5 over 9 EndFraction (F minus 32) = StartFraction 5 over 9 (45 minus 32) = 25 minus 32 = negative 7

What error did Alan make?
He substituted 45 for F instead of –7 and should have found the answer to be Negative 21 and two-thirds degrees Celsius.
He did not combine within the parentheses first before multiplying and should have found the answer to be 7 and StartFraction 2 over 9 EndFraction degrees Celsius.
He multiplied 45 by the fraction incorrectly and should have found the answer to be 49 degrees Celsius.
He divided 5F by 9 before subtracting 32 and should have found the answer to be 21 and StartFraction 4 over 9 EndFraction degrees Celsius.

What is 3x+8 ?
I believe you simplify.

Answers

Step-by-step explanation:

Simplifying x = 3x + -8 Reorder the terms: x = -8 + 3x Solving x = -8 + 3x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3x' to each side of the equation. x + -3x = -8 + 3x + -3x Combine like terms: x + -3x = -2x -2x = -8 + 3x + -3x Combine like terms: 3x + -3x = 0 -2x = -8 + 0 -2x = -8 Divide each side by '-2'. x = 4 Simplifying x = 4

Answers

Answer: x=8

Step-by-step explanation:

3(x-4)=12

Distribute the 3 into the parathesis'

3x-12=12

   +12 +12   on each side

3x=24

Divide by 3 on each side

x=8

8.
EXPLANATION.
because of pemdas. The equation in parenthesis must be first.
Knowing that the answer is 12.
And 1 factor is 3.
Since it is multiplication,
It is 3 x X = 12.
So x must be 4. 8 - 4 is 4.
So 8.

Every five years in February, the population of a certain town is recorded. In 1995, the town had a population of 6,500 people. From 1995 to 2000, the population increased by 8%. From 2000 to 2005, the population decreased by 5%. What was the percent of change in the town's population from 1995 to 2005?

Answers

Answer:

The answer is 3%

Step-by-step explanation:

From 1995-2000, it went up 8%. From 2000-2005, it went  down 5%. That means, to find the amount of change, we have to subtract 8 and 5, getting 3%. Hope this helped!

{0, 0.5, 1}
{0.5, 1}

Answers

Answer:

A

Step-by-step explanation:

it can't be any answer with 0, because when you substititue the variable a with 0, it simplifies to 3 ≥ 8 which is false, so C and D are incorrect. it also can't be B since when you substitue a with 1 it simplifies to 6 ≥ 8 which is also false. therefore A is the correct answer, hope this helps :)

Answer:

{2.5, 3}

Step-by-step explanation:

2a + 3 ≥ 8

2a + 3 - 3 ≥ 8 - 3

2a ≥ 5

[tex]\frac{2a}{2}[/tex] ≥ [tex]\frac{5}{2}[/tex]

a ≥ 2.5

From the expression above, a is equal to 2.5 and any number above 2.5

∴The answer is {2.5, 3}
