Answer:
it depends on how big the floors are.
Step-by-step explanation:
56 students represents 100 % and
X boys represent 34%,
so x= 56•34/100= 19.04 so approximately 19 boys
56-19= 37 girls signed up.
Now 37 girls represent 100% and 31 girls represent x % ,
So x= 31•100/37= 83.78% about 84% of the girls attended
The first one is the correct answer.
Answer:
3 AND 5
Step-by-step explanation:
LET THE TWO NUMBERS BE X AND Y
THEN
X + Y = 8 …….1
X – Y = 2 …… 2
WE SOLVE SIMULTANOUSLY
SUBTRACTNG EQATION 2 FROM 1
X – X + Y – (-Y) = 8 – 2
Y + Y = 6
2Y = 6
DIVIDING EACH TERM BY 2
2Y/2 = 6/2
Y = 3
THEN PUTTING Y = 3 IN EQUATION 1
X + 3 = 8
X = 8 – 3
X = 5
Answer:
Read below.
Step-by-step explanation:
Hey there, grab your solution:
x²+9x+16=0
Sqrt(D)=sqrt(17)
So x is:
(-9+sqrt(17))/2
And (-9-sqrt(17))/2
