Answer:
x = 8
Step-by-step explanation:
3(x−5) = 9 (by PEDMAS, distribute 3 into parentheses by distributive property)
x(3)−5(3) = 9
3x - 15 = 9 (add 15 to both sides)
3x = 9 + 15
3x = 24 (divide both sides by 3)
x = 24/3
x = 8
Answer:
The cube root of a number is a special value that, when used in a multiplication three times, gives that number. Example: 3 × 3 × 3 = 27, so the cube root of 27 is 3. See: Square Root. Cubes and Cube Roots.
Let's solve your equation step-by-step.
7(x+2)=6(x+5)
Step 1: Simplify both sides of the equation.
7(x+2)=6(x+5)
(7)(x)+(7)(2)=(6)(x)+(6)(5)(Distribute)
7x+14=6x+30
Step 2: Subtract 6x from both sides.
7x+14−6x=6x+30−6x
x+14=30
Step 3: Subtract 14 from both sides.
x+14−14=30−14
x=16
Answer:
x=16
Answer:
tan M = 
Step-by-step explanation:
To obtain tan M we require to find KL
Using Pythagoras' identity in the right triangle.
KL² + LM² = KM²
KL² + 7² = 25²
KL² + 49 = 625 ( subtract 49 from both sides )
KL² = 576 ( take square root of both sides )
KL = 
= 24
Then
tan M = 
= 
=
