Answer:
b = 2(g + r)
Marisa used b = 8 cups of blueberries.
Step-by-step explanation:
Let g be the cups of green grapes, r be the cups of red grapes, and b be the cups o blueberries Marisa used..
then we know that
g = 1 (Marisa used 1 cup of green grapes)
r = 3 (Marisa used 3 cup of red grapes)
g + r = 4
Marisa used twice as may cups of blueberries as cups of grapes; this means
b = 2(g + r )
b = 2(4) = 8
Marisa used 8 cups pf blueberries.
Answer:
<u>12 years</u>
Step-by-step explanation:
Let Kishor's present age be denoted by x.
According to the question :
- He will 3 times as old as he was 4 years ago after 12 years
Therefore, the equation is :
Solving :
- x + 12 = 3x - 12
- 3x - x = 12 + 12
- 2x = 24
- x = <u>12 years</u>
<u></u>
Hence, Kishor's present age is <u>12 years</u>.
The algebraic expression would be 4 - n, I believe.
H= -8. H-2h= 9-1; -h=8; h= -8
