Answer:
one student = 0.25
3.75 ÷ 0.25 = 15
15 students were tested by the teacher.
Step-by-step explanation:
<span>Simplifying
10 + -3(3x + -40) = -9x
Reorder the terms:
10 + -3(-40 + 3x) = -9x
10 + (-40 * -3 + 3x * -3) = -9x
10 + (120 + -9x) = -9x
Combine like terms: 10 + 120 = 130
130 + -9x = -9x
Add '9x' to each side of the equation.
130 + -9x + 9x = -9x + 9x
Combine like terms: -9x + 9x = 0
130 + 0 = -9x + 9x
130 = -9x + 9x
Combine like terms: -9x + 9x = 0
130 = 0
Solving
130 = 0
Couldn't find a variable to solve for.
This equation is invalid, the left and right sides are not equal, therefore there is no solution.</span>
1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, … these are the
Fibonacci numbers.
so add in +1,
we get
1+1,1+1,2+1, 3+1 ,5+1, 8+1 ,13+1, 21+1, 34+1, 55+1 ...........
2,2,3,4,6,9,14,22,35,56.........
so 22,35,56 is the answe
dont delete my answer again
