Solve for "w" by adding 15 to both sides of the equation.
5w-15=25
5w=40
Next, divide both sides by 5 to get "w" by itself.
5w=40
W=8
The diagonal of a rhombus divides it into two congruent isosceles triangles.
So ∠CBD ≅ ∠CDB
∠CBD + ∠CDB + 68 = 180
2∠CBD = 180 - 68 = 112
∠CBD = 56
We also have
∠BDE + ∠E + ∠DBE = 180
∠DBE = 180 - 73 - 36 = 71
∠EBC = ∠EBD - ∠CBD = 71 - 56 = 15
Answer: ∠EBC = 15 degrees
2(5x+4)+3(2x-1)
Use the distributive property for both sets of parenthesis:
2(5x+4) = 2*5x + 2*4 = 10x+8
3(2x-1) = 3*2x - 3*1 = 6x-3
Now you have:
10x+8 + 6x-3
Now combine like terms:
10x + 6x = 16x
8-3 = 5
The final answer is 16x+5
Answer:
- The height of the other book is <em>2 3/4</em> inches.
Step-by-step explanation:
<em>From the information,we get:</em>
Two stacks of books together are = 7 1/2 inches tall.
One stack is given,that is = 4 3/4 inches.
To Find:
Solution:
Let us assume that the other height of the book be x.
Then the equation will be:

- Solve for x to get the other book's height.
Convert the mixed fractions to fractions:

<em>Subtract 19/4 from both sides:</em>


<u>Hence, we can conclude that:</u>
The height of the other book is 2 3/4 inches.
Answer:
x = 5
Step-by-step explanation:
x^2 +2 = 27
x^2 = 27 - 2
x^2 = 25
x = 
x = 5
