Answer: b ≤ -18
<u>Step-by-step explanation:</u>
Isolate the variable by multiplying both sides by -3. Remember that when you multiply or divide by a negativem the symbol flips.
ANSWER
The correct answer is 4.6
EXPLANATION
Since U is the midpoint of |RS|,
U being the midpoint of RS means, it is in the middle of R and S.
So if from R to U is 2.3, then from U to S is also 2.3.
This is an implication that

Answer:
The perimeter of the triangle ABC is 17 cm.
Step-by-step explanation:
Consider the Isosceles triangle ABC.
The sides CA and CB are equal with measures, 5 cm.
The base angles are assumed to be <em>x</em>° each. Hence, the angle ACB is 2<em>x</em>°.
The altitude CP divides the base AB into two equal halves and the angle ACB is also cut into halves.
Consider the right angled triangle ACP.
The sum of all the angles in a triangle is 180°.
Determine the value of <em>x</em> as follows:
<em>x</em>° + <em>x</em>° + 90° = 180°
2<em>x</em>° = 90°
<em>x</em>° = 45°
Compute the length of side AP as follows:
Then the length of side AB is:
AB = AP + PB
= 3.5 + 3.5
= 7 cm
The perimeter of triangle ABC is:
Perimeter = AB + CA + CB
= 7 + 5 + 5
= 17
Thus, the perimeter of the triangle ABC is 17 cm.
