Answer:
4/16 ( 1 + 11) = 3
could be many answers as fractions see below
The last fraction seems more likely out the three or make it harder fraction.
Step-by-step explanation:
1/2 (2 + 4) = 3 as 1/2 of 4 is 2 1+2 = 3
or
1/4 (4 + 8) = 3 as 1/4 of 8 is 2 1+2 = 3
or
3/4 ( 2 + 2) = 3 as 3/4 of 2 is 1 1/2 1.5 + 1.5 = 3
or harder fraction
4/16 ( 1 + 11) = 3
Answer:
2x²−13x+21

Answer:
I don't know what it's asking but it could be 80
Step-by-step explanation:
Simply solve for x:
-x^2 + 9 = 0 => x = 3 and x = -3;
plug x = 3 and x = -3 into the original equation you get 3 = 3 and -9 = -9, respectively;
So, the two intersecting points are (-3, -9), (3, 3).
And of course, the parabola opens down since its square term is minus.
Answer:
Step-by-step explanation:
Let h be the number of hats Elliott makes and s be the number of scarves she makes.
Each hat uses 0.2 kilograms of yarn and each scarf uses 0.1 kilograms of yarn. Elliott wants to use twice as much yarn for scarves as for hats. This is expressed as
h = 2s
The total number of hats and scarves that she wants to make is 20. This is expressed as
h + s = 20
Therefore, the system of equations that represents this situation are
h = 2s
h + s = 20
