Answer:
D, -1/6
Step-by-step explanation:
-1/2+(3/4*4/9)
Multiply equation inside the parentheses
3/4*4/9=12/36=1/3
Substitute 1/3 into original equation
-1/2+1/3=1/3-1/2
Make denominators the same
2/6-3/6
Simplify
-1/6, D
Answer:
Step-by-step explanation:
area of the square =10*10=100
area of the circle =pi r^2=pi*1^2=3.142
part a
p(hitting the circle =3.142/100=0.03142 Which is closer to 0
part b
p( hitting the white portion ) =1-0.03142=0.96858 which is closer to 1
120 a month (1250-650 = 600, 600 divided by 5 = 120)
Answer:
x=2
y=1
Step-by-step explanation:
2x+y=5
3x+2y= 8
<=> 6x+3y=15
6x+4y=16
<=> -y=-1
2x+y=5
<=> y=1
2x+1=5
<=> y=1
2x=4
<=> y=1
x=2
Answer:
(1) x (x+ 3) - 4 (x +3) = 0
(2) x = 4 and x = -3
Step-by-step explanation:
given data
equation
(x−4)(x+3)=0
solution
given equation (x−4)(x+3) = 0
equation as a compound statement is
x (x+ 3) - 4 (x +3) = 0
and
two solutions to the equation are
so x (x+ 3) - 4 (x +3) = 0
x- 4 = 0 and x + 3 = 0
x = 4 and x = -3
