Step-by-step explanation:
Let the initial fundraising goal be 100.
as per the given statement your school raised 125% of its fundraising goal.

Equivalent ratios are two ratios that express the same relationship between numbers.
then, By equivalent ratio :
after cross multiply we get;
Divide both sides by 125 we get;
Simplify:
x = 5400

Answer:
a=5
Step-by-step explanation:
x^2 + ax + 6 = (x + 3)(x + 2)
FOIL the right hand side
first: x*x = x^2
outer: x*2 = 2x
inner: 3*x = 3x
last : 3*2 = 6
add them together
x^2 +2x+3x+6 = x^2 +5x+6
x^2 + ax + 6 = x^2 + 5x+6
a=5
8.7352 rounded to the nearest tenth is: 8.7, because the tens place is 0.7 in this situation and looking at the next number, 3 is less than 5 so when rounding you keep the 7 the same.
