Answer:
10+6=16
Step-by-step explanation:
So, we know that a^2 + b^2 = c^2. Right? That is called the Pythagorean Theorem.
In this case. We can say that 39 is a, 40 is b, and x is c.
NOTE: It doesn't really matter whether 39 is a or b. a & b are just the two legs of the right triangle.
So, if we say that 39 is a, 40 is b, and x is c. We can plug it into the Pythagorean Theorem.
39^2 + 40^2 = x^2
I'll let you take it from there.
The boys drink 7/10 of a water bottle
1. Convert 2/5 into 4/10
2. Add 4/10 and 3/10
I agree with the second answer. Was this correct?
get a common denominator which is 12
2 1/3 = 2 4 /12
5 3/4 = 5 9 /12
2 4/12 + 5 9/12 = 7 13/12
7 + 1 1/12
8 1/12
