Out of the total 60 students 18 take Algebra 1 and 20 take Algebra II. 10 take both. So out of the 18 taking algebra 10 are taking Algebra II. If we don't count that 10 because they are already counted in Algebra II count. So 28 students are taking either course. Therefore 60-28 = 32 students who are not taking either of these courses
Answer:
Henry will need 6 pints of red color.
All together he will need 15 pints.
Step-by-step explanation:
Henry needs 2 pints of red paint and 3 pints of yellow paint to get a specific shade of orange.
The ratio is 2:3
Now he uses 9 pints of yellow paint so we need to find the pins of red paint used to get the same orange.
Let the pints of red paint be x
We can relate this as:

Solving for x;

So, x = 6
Hence, 6 pints of red color are needed.
And all together Henry needs
pints of paint.
Answer:
a₁ = 10
Step-by-step explanation:
The common difference d is calculated as
d = a₃ - a₂ = - 20 - (- 5) = - 20 + 5 = - 15
Then
a₂ - a₁ = d , that is
- 5 - a₁ = - 15 ( add 5 to both sides )
- a₁ = - 10 ( multiply both sides by - 1 )
a₁ = 10
