There are 8 more males in Sara's class than females. If 3/5 of the students are male, how many students are in Sara's class?
Answer:
40 students
Step-by-step explanation:
Let
Total students in Sara's class = x
Number of males = 3/5x
Number of females = Total students - male students
= x - 3/5x
= 5x-3x/5
= 2/5x
Number of females = 2/5x
There are 8 more males in Sara's class than females.
Therefore,
Males = 2/5x + 8
Total number of students = number of males + number of females
x = 2/5x + 8 + 2/5x
x = 2x+2x/5 + 8
x = 4/5x + 8
x - 4/5x = 8
5x-4x/5 = 8
1/5x = 8
Divide both sides by 1/5
x = 8 ÷ 1/5
= 8 × 5/1
x = 40
Therefore, there are 40 students in Sara's class
Check
Males = 3/5x
= 3/5×40
= 3×8
= 24
Females = 2/3x
= 2/5 × 40
= 2 × 8
= 16
Therefore, there are 8 more males than females

The depths of two scuba divers exploring a living coral reef are shown. a. Write an integer for the position of each diver relative to sea level. The position of the diver on the left relative to sea level is feet. The position of the diver on the right relative to sea level is feet. b. Which integer in part (a) is greater? is greater. c. Which integer in part (a) has the greater absolute value? has the greater absolute value.
Answer:
a: left = 14 feet
right = 18 feet
b: 18 is significant
c: absolute value is 18
Step-by-step explanation:
a)
The position of the diver on the left relative to the sea level is 14 feet.
The position of a diver on the right to sea level is 18 feet.
b)
integer 18 in part (a) is more significant.
c)
Absolute value is the distance and the zero on the number line.
Absolute value of |18| = 18
Absolute value of |14| = 14
Hence the most excellent absolute value is 18.
there are 10 mm in 1 cm convert 27 cm to millimeters
simplify 5(a+6)−a+7a−18
Answer:
11a + 12
Step-by-step explanation:
For this problem, we will simply use the distributive property both forwards to gather all of the like terms, and then backward to simplify the like terms.
5 ( a + 6 ) - a + 7a - 18
= 5a + 30 - a + 7a - 18
= 5a - a + 7a + 30 - 18
= a ( 5 + -1 + 7 ) + 30 - 18
= a ( 4 + 7 ) + 12
= a ( 11 ) + 12
= 11a + 12
Hence, the simplification for 5(a+6)-a+7a-18 is 11a + 12.
Cheers.

Step-by-step explanation:
Find the inverse of the function f(x) = x3 + 5
Answer:
[tex]{f}^{ - 1} (x) = \sqrt[3]{x - 5} [/tex]Step-by-step explanation:
[tex]f(x) = {x}^{3} + 5[/tex]
To find the inverse of f (x) , equate f(x) to y
That's
y = f(x)
[tex]y = {x}^{3} + 5[/tex]
Next interchange the terms
That's x becomes y and y becomes x
[tex]x = {y}^{3} + 5[/tex]
Next solve for y
Send 5 to the other side of the equation
[tex] {y}^{3} = x - 5[/tex]
Find the cube root of both sides to make y stand alone
That's
[tex] \sqrt[3]{ {y}^{3} } = \sqrt[3]{x - 5} [/tex]
[tex]y = \sqrt[3]{x - 5} [/tex]
We have the final answer as
[tex] {f}^{ - 1} (x) = \sqrt[3]{x - 5} [/tex]

Don’t do 7. And nine it been done already
Answer:
Step-by-step explanation:
8. subtract 78 from both sides so you get r=-93
10. divide both sides by 8 so you get j=12
11. divide both sides by -13 so its z=3
12.divide both sides by 15 so its m=-12
13. divide both sides by 27 to get r=9
14. multiply both sides by 9 (9/1) to get y=-72
15. multiply both sides by 12 to get -j=-96 then divide it by - to get j=96
16. multiply it by 15/1 so its a by itself and then use cross multiplication to simplify it so 4/5 x 15/1 so 15 becomes 3 and 5 becomes 1 so its 4x3 which is 12 so a=12

three times the absolute value of the sum of a number and 6
Answer:
[tex]3|x + 6|[/tex]
Step-by-step explanation:
Required
Get the equivalent of the given statement
Let the number be represented by x
So:
Sum of a number and 6 will be:
[tex]Sum =x + 6[/tex]
The absolute value will be:
[tex]Absolute = |x + 6|[/tex]
Three times this will be:
[tex]Product = 3 * |x + 6|[/tex]
This can be further represented as:
[tex]Product = 3 |x + 6|[/tex]
Hence, the equivalent of the given statement is [tex]3|x + 6|[/tex]
