110 girls and 85 boys.
Subtract 1 from 195. Then divide by 2. 194/2 = 97. Then add 13 97+13=110. There are 110 girls.
Answer:
x=3, y=-2, z=1
Step-by-step explanation:
I solved by substitution
The < and > signs mean lesser and greater than. = means equal(s). The signs will always look like they are eating the bigger value. For example:
12<29
Twelve is lesser than twenty-nine, or
29>12
Twenty-nine is greater than twelve.
An equation uses an equal sign
12+8=20
When you're using all of them, it can look like this:
1<n<29
This is read as "one is lesser than n which is lesser than 29". These can be used to determine the lengths of the sides of a triangle. In this case, n must be between 1 and 29 for it to be the side of a triangle.
Answer:
6x ≥ -24
An inequality is "a statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions."
The solution to this inequality is:
x ≥ -4
Step-by-step explanation:
There's no explanation needed.
I just converted the words into an equation, then solved it by dividing both sides by 6. I looked up the definition of an inequality and pasted it here.
Solution:
Given: ABCD is a Rhombus
To Prove: ΔABC≅ΔCDA
Construction: Join AC as diagonal.
Proof: ABCD is Rhombus whose sides are equal and diagonal are perpendicular bisectors. Please see attach figure.
In ΔABC and ΔCDA
AB=CD (Side of same Rhombus)
BC=DA (Side of same Rhombus)
AC=CA (Common Side of both triangle)
Therefore, ΔABC≅ΔCDA by SSS property of congruence.
Hence Proved, ΔABC≅ΔCDA
