To solve this you multiply -4.5 by 2.5
Your answer is -11 and 1 /4
The other number is 5 less than 3 times the other so the other number will be
3x-5
We are given that they add up to 31, so we can write
x+(3x-5) = 31
4x - 5 =31
Answer: The answer is option C: 10cm, 6cm and 8cm
Step-by-step explanation: A right angled triangle has an hypotenuse (the longest of all three sides) facing the 90 degree angle. Also a right angled triangle can be solved by means of the Pythagoras theorem which states that;
AC^2 = AB^2 + BC^2
Where AC is the hypotenuse (10cm) and AB (6cm) and BC (10cm) are the other two sides.
If that is the case, we can insert the values as given in option C to know whether or not they make up a right angled triangle. Therefore
10^2 = 6^2 + 8^2
100 = 36 + 64
100 = 100
Therefore the side lengths 10cm, 6cm and 8cm satisfies the requirements for a right angled triangle
Alright so lets break this down!
What we are looking at is:
y = 3x - 4
the question is
<em>what is the value of x when y = 5?</em>
This means all we have to do is plug in 5 for y and solve for x
y = 5
x = ?
therefore,
5 = 3x - 4
Now some algebra,
5 + 4 = 3x
9 = 3x
9/3 = x
<em>3 = x</em>
Now our concluding statement:
The value of x is 3 when y is equal to 5
Sometimes all you have to do is turn words into numbers and numbers into words!
Good luck! I hope this was helpful.
Answer:
30 feet
Step-by-step explanation:
If they are equal, just divide 360 by 12.
360 ÷ 12 = 30
