Answer:Amount of rice cooked by Alice =2 11/24kg
Together Alice and Jasmine cooked 4 7/24kg of rice
Step-by-step explanation:
Amount of rice cooked by Jasmine =1 5/6 kg
Amount of rice cooked by Alice = 5/8 kg more than Jasmine
=1 5/6 kg+ 5/8 kg
=1 (20 +15) /24
=1 35/24
=1 +1 11/24
= 2 11/24 kg
Together Alice and Jasmine cooked 1 5/6 kg + 2 11/24kg =
=3 20 +11/24
=3 31/24=3 +1 7/24
=4 7/24kg
Given quadratic equation
Using the usual conventions,
a=1, b=6, c=6
Apply the quadratic formula,
substitute a,b & c with numerical values,
simplify:
Answer:
-1/2 or x=2
Step-by-step explanation: The first step you need to do in getting your answer is factoring ,you will factor the left side of the equation first:
(2x+1)(x-2)=0
Next, you will set the factors to equal to "0":
2x+1=0 x-2=0
Then you'll proceed to solve the problem using the basic algebraic equation problem solving steps .When you do this you'll be left with answers of x=-1/2 and x=2
Answer:
7 are boys
Step-by-step explanation:
Make a system of equations where g is for girls and b is for boys.
b+g=26
g=3b-2
Substitute "3b-2" in for "g" in the first equation.
b+(3b-2)=26
Rewrite without the parentheses because it's addition and not multiplication.
b+3b-2=26
Combine like terms.
4b-2=26
Add 2 to both sides.
4b=28
Divide by the coefficient of the variable to get it alone.
b=7
