Step-by-step explanation:
that is half of 2 and 3/4
Answer:
No solutions
Step-by-step explanation:
Hello!
To solve for x, we should expand the parenthesis and isolate the variable x.
<h3>Solve for x</h3>
- 6(1 + 5x) = 5(1 + 6x)
- 6 + 30x = 5 + 30x
- 6 ≠ 5
The are no solutions for x, as 6 does not equal to 5.
Answer: (B) 130 cm
Proof: If a chord and a line from the centre meet, they must be perpendicular. The line from the centre to the chord also bisects the chord. If the distance from the centre of the circle to the chord is 52 cm and the distance of half of the chord is 39 cm, then you can work out using Pythagoras' Theorem the distance of the radius.
r² = 52² + 39²
r² = 4225
r = 65
Thus, the diameter is 2r = 130 cm
Answer:
there are 6.45 or 6.5 square cm in one square inch
Step-by-step explanation:
The answer: " x = 5 " .
____________________________________
Explanation:
____________________________________
Given: " x = √(15 <span>− 2x) " ; Solve for "x" ;
____________________________________
"Square" each side of the equation:
____________________________________
</span> → (x)² = [√(15 − 2x) ] ² ;
→ x = 15 − 2x ;
Now, add "2x" to each side of the equation:
→ x + 2x = 15 − 2x + 2x ;
→ 3x = 15 ;
Now, divide each side of the equation by "3" ;
to isolate "x" on one side of the equation; & to solve for "x" ;
→ 3x / 3 = 15 / 3 ;
→ " x = 5 " .
