X equals 60 because 2x60=120. and 120-10=110
Answer:
Step-by-step explanation:Use the square root on both sides:
x
–
5
=
±
√
3
Add 5 to both sides:
x
=
5
±
√
3
This breaks into two equations:
x
=
5
+
√
3
and
x
=
5
−
√
3
Use the square root on both sides:
x
–
5
=
±
√
3
Add 5 to both sides:
x
=
5
±
√
3
This breaks into two equations:
x
=
5
+
√
3
and
x
=
5
−
√

Answer:
7
Step-by-step explanation:
Take the new height and divide by the original height to determine the scale factor
56/8 = 7
We can check this by using the length
35/5 =7
The scale factor is 7
divide 13 by 3
13/3 = 4.33 put a bar over the 2nd 3 because it just keeps repeating.
Use all the top to multiply by it
Then divide by the buttom.
