Answer:
1/4 of 10 is 2 1/2
then 7 1/2 is left
(2x+1)=Jeremy´s age
(2x+3)=Sam´s age.
we suggest this equation:
(2x+1)(2x+3)=783
4x²+6x+2x+3=783
4x²+8x-780=0
x²+2x-195=0
We solve this quadratic equation:
x=[-2⁺₋√(4-4*1*(-195))]/2=(-2⁺₋28)/2
x₁=(-2-28)/2=-15 this solution is not valid.
x₂=(-2+28)/2=13
Jeremy´s age=2x+1=2*13+1=27
Sam´s age=2x+3=2*13+3=29
The answer is A. It says that circle b is 16 times greater so yeah its A.
Answer:
9 + 22h
Explanation:
The question is incomplete as Gordon's height is not given. To solve further, we will represent this height with h
So, we have:
nine more than the
of 22 and 
More than, in this case means plus (+)
nine + the
of 22 and 
Rewrite nine as 9 and substitute h for Gordons height
9 + the
of 22 and h
product, in this case means multiplication (*)
9 + 22 * h
So, the expression is:
9 + 22h
It would be $27.96 because if you take half of 18.64 and add that answer to 18.64 you would get the total
for 6 pounds
