Answer:
Step-by-step explanation:
triangle area = (length*width)/2
height(length): x
base(width): 8x
area = 45
8x^2=45
solve for x
180*60%=180*60/100=10800/100=108
180+108=288
So the total population os school is 288 students!

Answer:
31
Step-by-step explanation:
a=(180-121)=59
c=(180-90)=90
180-59-90=31
25/28 - 2/7
it doesn’t need to be solved because it asked for an expression and not an equation, so no equal sign either
I think it is negative five
