Answer:
Step-by-step explanation:
The system of equations is:
● 3x + 2y = 7
● 2x + 4y = 8
Where x is the price of a single coffee and y is the price of a single coffee
We will solve this simultaneous equations using the graphing method:
The solutions is the intersection point of to the lines.
(Picture below)
The intersection point is (1.5,1.25)
Answer:
30 Bows
Step-by-step explanation:
Every yard is 3 feet, and each bow calls for 1/3 of a yard, so a foot per bow.
So you can make 10 yards, 30 feet by multiplying by 3, and then its pretty straight forward from there. 30 / 1 = 30 Bows
Let X = pounds of Bermuda grass needed.
(20 pounds bahia grass x $6.30) + ( X x $3.65) = (20 +X) x $4.90
Simplify:
126 + 3.65X = 98 + 4.90X
Subtract 3.65X from each side:
126 = 98 + 1.25X
Subtract 98 from each side:
28 = 1.25X
Divide both sides by 1.25
X = 28 / 1.25
X = 22.4 pounds required.
