We know that the lengths of the two smaller sides have to be more than the third side when they are added together
The third side couldn't be 2 or 3 because 9 (7+2) or 10 (7+3) are not less than 10
The third side couldn't be 17 or 18 because 17 (7+10) is not larger than 17 or 18
The correct answer is C. 4 works because 7+4=11 or more than 10. 16 works because 7+10=17 is more than 16
Hope this helps
5/16 = n/80
bring 80 over to the other side to leave n alone. 80 then gets a multiplication sign in front of it.
5/16 x 80=n
5/16=0.3125
0.3125x80=25
n=25
hope this helps
Answer:
19
Step-by-step explanation:
The markings on the triangle means that this is an equilateral triangle (All sides are the same length)
So, we can set the two equations we have equal to each other
4x + 7 = 3x + 10
x + 7 = 10
x = 3
Plug it into either equation
3(3) + 10 = 19
You will have to add your whole then multiply your fraction
