Here you have the solution to this task.
Answer:
b1 = (28/h) -b2
Step-by-step explanation:
Filling in the given value for A, you have ...
14 = (1/2)(b1 +b2)h
Multiply by 2/h:
28/h = b1 +b2
Subtract b2:
b1 = (28/h) -b2
To start you find the total amount of money they need by adding the registration fee and the equipment.
572 + 1240 = 1812
Then you find out how much they still need after the car wash.
1812 - 786 = 1026
Now you set up what you have in an equation. You know that 9.50 per candle equals out to be a total of $1026.
9.50x = 1026
9.50x/9.50 = 1026/9.50
x = 108
So you now know that they need to sell 108 candles to get the remaining money. So now you must figure out how many candles each player needs to sell.
108/12 = 9
Each player needs to sell 9 candles.
D. 11,475 (135/200= .675 =67.5 %) (67.5% x 17,000 = 11,475)
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
