Answer:
y=1
Step-by-step explanation:
6=2(y+2) distribute your first 2 outside of the (_)
6= 2y+4 then subtract 4 from both sides
Then you will have 2= 2y divide both sides by the 2 from 2y
After you have 1=y
Plug the new y value back in and you will have
2(1+2)= (_) always goes first so you will have 3
2(3) when you have a number beside of a (_) you multiple and receive the answer that this equals 6 to check yourself
X=10 let me know if you need the work
Step-by-step explanation:
lets radius be r and height be h,
r+h=21 -----(1)
curved surface area
2×pi×r×h=616 -----(2)
use simultaneous eqn to solve for r and h.
total surface area of cylinder= 2×pi×r×h + 2×pi×r²
= ans if im not wrong
To answer the question, let x be the number of pounds of coffee worth $9. Having said that, the number of pounds of coffee worth $3 is 120 - x. The equation relating the items before and after mixing is,
(x)($9) + (120 - x)($3) = (120)($5)
The value of x is 40. Therefore, the amount of coffee worth $9 and $3 to be used are 40 and 80 pounds, respectively.
