Answer:
W=191,000MWH S=27,000MWH
Step-by-step explanation:
OK, let's W be wind electricity generated and S, solar electricity generate.
TOTAL GENERATED: <u>218,000mwh = W + S </u>
RELATION BETWEEN W AND S: <u>W = 2,000mwh + 7S</u>
We have now two equations:
218,000 = W + S
W = 2,000 + 7S
Put th value of W into the 1st equation in order to find S:
218,000 = 2,000 + 7S + S
218,000 = 2,000 + 8S
218,000 - 2,000 = 8S
216,000 = 8S
S = 216,000/8
S = 27,000mwh
Now, we find W.
W = 2,000 + 7*27,000mwh
W = 2,000 + 189,000mwh
W = 191,000mwh
Answer: x=13
Step 1: Define isosceles triangle
In an isosceles triangle, two sides and angles are equal. The equal sides will be the legs.
Step 2: Write an equation
To write an equation we must first consider the information discussed in step 1. Since we know that the legs will be equal, we will add that to the equation twice. The base and legs will be on one side of the equation, and the perimeter will be on the other. Now we can write the equation!
x+3x-7+3x-7=77
Step 3: Combine like terms
Like terms are terms that share the same variable, or lack of. Let’s add/subtract these now.
x+3x-7+3x-7=77
7x-14=77
Step 4: Solve for x
Let’s do the last part of the equation and solve for x, our final answer.
*Rewrite equation*
7x-14=77
*Add 14 to both sides*
7x=91
*Divide 7 on both sides*
x=13
