The first two pieces are the same, let each of those equal x, so you have x + x = 2x
The 3rd piece is the sum of the first two + 4, so this would be 2x + 4
Now you have 2x + 2x + 4 = 100 cm
Combine like terms:
4x +4 = 100
Subtract 4 from both sides
4x = 96
Divide both sides by 4
X = 24
First piece is 24 cm
Second piece is 24 cm
Third piece is 52 cm
Hey there!
In a rhombus, opposite angles are congruent. This means that 2y is equal to y+34. Let's set up an equation to solve for y.
2y=y+34
We subtract y from both sides.
y=34
Therefore, y=34°
I hope that this helps! Have a wonderful day!
Answer:
840
Step-by-step explanation:
I=PRT
I =4000 x 0.07 x 3
I=840
the domain:
the equation:
4 is in the domain
-2 is not in the domain
The answer:
***
Also, the answer in 13 is {8}. -3 is not in the domain. Replace x with -3 and you'll see:
It's not true so -3 isn't a solution to this equation.
