Answer:
24
Step-by-step explanation:
132 pupils are represented by 11 parts of the ratio
Dividing 132 by 11 gives the value of one part of the ratio
132 ÷ 11 = 12 ← value of 1 part of the ratio, hence
2 parts = 2 × 12 = 24 ← number of teachers on trip
It equals 1 1/6 + d.
In other words, one and one sixth plus d.

Answer:
The roots of the equation are x=-3 and x=-2.5
Step-by-step explanation:
<u><em>The correct quadratic equation is</em></u>
2x^2+11x+15=0
we know that
The formula to solve a quadratic equation of the form
is equal to
in this problem we have
so
substitute in the formula
therefore
The roots of the equation are x=-3 and x=-2.5
