You use PEMDAS.
First, parentheses
(x+4) = 4x
(3x+5) = 3x+5
So, that is
4x*3x+5
Then, exponents. We don’t have any.
Then, multiplying.
4x*3x is 12x
So, 12x+5
And then, division. We don’t have anything to divide.
Then, addition and subtraction
You can’t add the variable to a number, so the answer is just
12x+5.
Hope it helped. :)
Let the number = 10x+y
x+y = 9
y-x = 1
(x+y)+(y-x) = 9+1
2y = 10
y = 10/2
<h3><u>y = 5</u></h3>
x+y = 9
9-y = x
x = 9 - 5
<h3><u>x = 4</u></h3>
<h2>So, your number is <u>45</u></h2>
... Hope this will help...
Answer:
65°
Step-by-step explanation:
If you add all the angles in a triangle, they equal 180°. You can subtract given angles to find missing angles.
Let's first subtract 25° from 180°. 180° - 25° = 155°.
This is a right triangle, so we know there is also a 90° angle. Also subtract this. 155° - 90° = 65°.
We are left with 65°. This is the measure of the third angle.
The triangle's angles are, 25° ; 90° ; 65°
