Your answer is B: 21/24
21/ 3= 7
24/3 = 8
Hope this helps :)
\begin{cases}4 x + 7 y = -{25} \\ 2 x - 7 y = -{23} \\ \end{cases}
x= the number of girls competing
x+16=the number of boys competing
The equation to find the number of boys and girls competing would be:
x+(x+16)=1000
First, combine like terms:
2x+16=1000
Subtract 16 from both sides.
2x=984
Divide both sides by 2:
x=492
We know now that the number of girls competing is 492. To find the number of boys competing, you simply have to add 16 to 492.
492+16=508
There are 508 boys competing and 492 girls competing.
I hope this helps :)
Answer:
(B)
Step-by-step explanation:
We have to construct two equilateral triangles that is one with the side length of 2 inches and the another triangle with side length of 3 inches.
Now, both the triangles are equilateral triangles, thus they have same shape.
Also, both triangles have different side lengths, one having 2 inches and another having 3 inches, thus they have different size.
Hence, the true statement about the two triangles is:
The two triangles are the same shape but not the same size.
Therefore, option B is correct.
