Answer:
-7°F/hour.
Step-by-step explanation:
If the total change is -28°F, and we know it took 4 hours, we just have to divide the total change by hours taken to get the change per hour.
So we do the following: [tex]\frac{-28F}{4} = -7F/h[/tex]
So the temperature changes (drops) by -7°F/hour.
During flu season, there were 93 students out of school on a particular day. If this is 12% of the total number of students at the school, how many total students are enrolled at the school?
The total students that are enrolled at the school is = 868 students
Calculation of total studentsIn the flu season the number of students absent from school = 93
The percentage of students absent from school = 12%
If 93 students = 12%
X students = 100%
Make X the subject of formula,
X = 93× 100/12
X= 9300/12
X = 775
Therefore, 775 + 93 = 868
The total students that are enrolled at the school is = 868 students.

—7y - 17 = -38 show your work
Answer:
y = 3
Step-by-step explanation:
Given
- 7y - 17 = - 38 ( add 17 to both sides )
- 7y = - 21 ( divide both sides by - 7 )
y = 3
Answer:
[tex]y=3[/tex]
Step-by-step explanation:
[tex]-7y - 17 = -38[/tex]
Add 17 both sides
[tex]-7y - 17 + 17= -38+17[/tex]
[tex]7y= -21[/tex]
Divide both sides by -7
[tex]\dfrac{-7y}{-7}=\dfrac{-21}{-7}[/tex]
[tex]y=3[/tex]
Amelia ,Hayden and Sophie did a test the total for the test was 75 marks Amelia got 56% of 75 marks Hayden got 8/15 0f the 75 marks Sophie got 43 out of 75 marks who got the highest
Step-by-step explanation:
Amelia got 56% of 75 so
(56/100)*75=(56*75)/100=4200/100=42
Hayden got 8/15 of 75 so
(8/15)*75=(8*75)/15=600/15=40
and Sophie that got 43 out of 75
so we see that Sophie got the highest points.
Given parameters:
Total test score = 75marks
Percentage of Amelia score = 56%
Fraction of Hayden's score = [tex]\frac{8}{15}[/tex]
Sophie's score = 43marks
Unknown:
The person with the highest score = ?
Solution:
Since total score = 75marks;
Amelia's score = [tex]\frac{56}{100} x 75[/tex] = 42marks
Hayden's score = [tex]\frac{8}{15} x 75[/tex] = 40marks
Sophie's score = 43 marks
The person with the highest score is Sophie with a mark of 43.

Ten times the sum of half a number x and 8 is 12.
BREAKDOWN
10 times: 10 ×
The sum of: ( ) + ( )
which would be : 10 × ( ) + ( )
half a number: 10 × ( X/2 ) + ( )
and 8: 10 × ( X/2 ) + ( 8 )
is 12 : 10 × ( X/2 + 8 ) = 12
xxxxxxxxxxxxxxxxxxx
SIMPLIFICATION
Multiply ten: 10 X (X/2 + 8) = 12
which equals to: 5x + 80 = 12
bring the like terms together: 5x = 80 - 12
Equals: 5x = 78

Solve the literal equation
x = a + b + c
————
ab
Answer:
a = xab/(b + c)
Step-by-step explanation:
x = (a + b + c)/ab
Isolate the variable by multiplying/dividing everything, but variable a to both sides
x × ab/(b+ c) = (a + b + c)/ab × ab/(b + c)
xab/(b + c) = a
