I believe x=0 ............................
I think you mean 87 degree angle, but all you'd have to do is subtract 180 with 87, to get 93 degrees.
good luck
x
Answer:
5.43
Step-by-step explanation:
I think boys =18
girls=12
boys :x
girls:y
student:z
the number of group for the boys :n
the numberof group for the girls :m
so x=(3/5)*z
y=(2/5)* z
x/y=3/2
3y-2x=0
(1/10)*z*n=(3/5) *z
so n=6
(1/5)*z*m=(2/5)* z
put x=(1/10)*z*6
y=(1/5)*z*2
into 3y-2x=0 and z=30
z=30 so x=(1/10)*30*6=18
y=(1/5)*30*2=12
Answer:
answer = 7000
Step-by-step explanation:
let the number be X
therefore, 91% × X = 637
or. 91 / 100 × X = 637
or. x = 637 × 100 ÷ 91
or. x = 700
