Your rows would be $0.90 Chocolate, $1.20 Chocolate, and the Total Chocolate Mix, and your columns would be the Amount of Chocolate in #s and the Total Costs
(This is the best I can do coming up with a grid)
________________amt (#)_________total costs
$0.90_____________10______________9.00
$1.20______________x______________1.20x
Total Mix_________10+x_____________9+1.2x
Using this grid, you see that 10+x=9+1.2x so solve for x
10+x -x=9+1.2x -x
10=9+.2x
10 -9=9+.2x -9
1=.2x
1/.2=(.2x)/.2
x=5, so you need 5lbs of the $1.20 chocolate to produce a mixture worth $1.00

Answer:
16=x
Step-by-step explanation:
So, The angle is 180 degrees
180-87=93
93=(6x-3)
Add 3 to both sides
96=6x
Divide 6 on both sides
16=x
Answer:
The formula to find the surface area of a sphere is to take the radius of the sphere and square it and multiply that amount by pi and then multiply that by 4. This is written algebraically as S=4πr2, where S is the surface area, r is the radius, and the value of π is 3.14.
