Answer:
17
Step-by-step explanation:
There are a total of 39 students.
students.
The number of students that play football is twice as much as the number of students that play volleyball.
Let the number that plays volleyball be x then the number that plays football will be 2x. This we have
x + 2x = 39
3x = 39
x = 13
The total number that plays volleyball is 13.
The total number that plays football will be 2 x 13 = 26
Since 9 students play both sports, the number of students that plays only football will be 26 - 9 = 17.
It about linear equations
Answer:
plant 1 i think
Step-by-step explanation:
Answer:
Plant 2 grew faster
Step-by-step explanation:
The slope of plant 1 is 3
(each day the plant grew 3cm)
The slope of plant 2 is 5
(each day the plant grew 5cm)
The slope of plant 3 is 1.5
(each day the plant grew 1.5cm)
each dye color is needed
Answer:
We can call the amounts of red, gray, and brown dye 1 1/8x, 3/4x and 5/8 x respectively and we can write the equation:
1 1/8x + 3/4x + 5/8x = 20
2 1/2x = 20
x = 8 which means that the stylist needs 1 1/8 * 8 = 9 oz red, 3/4 * 8 = 6 oz gray and 5/8 * 8 = 5 oz brown.

The nth term for the given arithmetic sequence 45, 40, 35, 30 is 50 - 5n.
45, 40, 35, 30
The general formula for the nth term (an) of an arithmetic sequence is:
an = a1 + (n-1)d
where a1 is the first term and d is the common difference.
Plugging in the values from the given sequence, we can find the nth term:
an = 45 + (n-1)(-5)
Simplifying further, we get:
an = 50 - 5n
So, the nth term of the sequence is 50 - 5n.
