Answer:
x=0.875
Step-by-step explanation:
3x-6=2-5x
Add 6 on both sides (6+2)
2x=8-5x
Add 5x on both sides
7x=8
Divide 7 from both sides
x=0.875
Answer:
See explanation
Step-by-step explanation:
You forgot to give the coordinates of C.
Note that, the mapping for 90° clockwise rotation around the origin is given by:

Assuming the coordinates of C were (-6,6), then the coordinates of C after a 90° clockwise rotation
around the origin is (-6,-6)
Answer:
x = 9
Step-by-step explanation:
AB = 4x + 6 and BC = 7x + 15 AC is the sum of AB and BC
so 4x + 6 + 7x + 15 = 120 add like terms
11x + 21 = 120 subtract 21 from both sides
11x = 99 divide both sides by 11
x = 9
Answer: <em>12j+14</em>
Step-by-step explanation:
<em>Take your equation that is given</em>
<em>6+5j+8+7j</em>
<em>Now combine like terms</em>
<em>5j+7j=</em><em>12j</em>
<em>6+8=</em><em>14</em>
<em>12j+14</em>
Answer:
11.2 feet
Step-by-step explanation:
Given: Height of platform (Opposite)= 5 foot
Distance of slope from the base of platform (adjacent)= 10 feet
Picture drawn to show the measurement.
Lets find the length of slope.
Using the Pythagorean theoram.

Subtituting the value in the formula.

⇒ 
⇒ 
Putting square root on both side
We know, √a²= a
⇒ 
∴ hypotenous= 11.18 
Hence, the slope is 11.2 feet
