Since there is a right angle, you can use Pythagoras' Theorem:
So x = √(24² + 7²) = 25

Answer:
25
Answer:
Step-by-step explanation:
We have been given two expressions 
and
Now we need to find out least common multiple of these two expressions.
First we need to find out what is common factor of both expressions. and
Least common multiple means find the expression which can be divided by both expressions.
15 and 6 both goes into 30
so 30 is part of LCM (least common multiple )
Now pickup the highest exponent of each variable.
So we get 
Hence required least common multiple is
First we define variables:
x: Money Peter receives
y: Money Paul receives
z: Money Jane receives
We write the system of equations:
x / y = 13/12
x / z = 13/7
x = z + 78
Solving the system we have:
x = $ 169
y = 156 $
z = 91 $
Answer:
Paul gets 156 $
Answer:
Answer is 28/4 = 7
Step-by-step explanation:
Given
Beth B = 28 problem
B has 4 times more problem than Mery m
Find
Total number of problem Mery m has if Beth has 4 times more problem than Beth
So,
B = 4 x m
m = B/4 = 28/4 = 7
Finally answer (d) is correct which is 28 ÷ 4 = m
