If I’m correct it should turn into a negative
0,-9
Add 50 to both sides
x-50=70
+50 +50
-50+50=0
70+50=120
x=120

Step-by-step explanation:
- Rectangle has properties:
- Diagonals are congruent
- Opposite sides are congruent
- All angles are right
<h3>Given</h3>
- m∠ABD = 30°
- AC = 16 in
- BC = ?
<h3>Solution</h3>
<u>As per properties mentioned above we have:</u>
ΔABD is right triangle with ∠B - 30°, ∠A- 90°, ∠D - 60°
Side opposite to 30 is half of the length of the hypotenuse
<u>AD is opposite to ∠B and BD is the hypotenuse, then:</u>
- AD = 1/2*BD
- AD = 1/2(16)
- AD = 8 in
and
Answer:
Here you go!
Step-by-step explanation:
Since we are not yet sure what our number is, we should use a variable to represent that number, and then solve for that variable.
I will use "x" as our variable to represent the number we are trying to find.
Let's take the problem piece by piece.
Six less than four times a number.
If we are using x to represent our number, we know that when we do four times that number we are multiplying x times 4, which is the same as writing "4x."
Next we know that we are taking six less than 4x. Six less than means we will be subtracting 6 from our 4x, which is the same as writing 4x - 6.
Finally, we know that six less than 4x (4x - 6) equals 15. Now we have a full equation:
4x - 6 =15
Now we have to solve for x by getting x by itself:
4x - 6 = 15
add 6 to both sides to move the 6 away from the x
4x = 21
now divide by 4 to get x by itself
x = 21/4, in decimal form this is 5.25
