Note the equal sign. What you do to one side, you do to the other. Isolate the p. Do the opposite of PEMDAS.
first, subtract 5r from both sides
2p + 5r (-5r) = q (-5r)
2p = q - 5r
Next, divide 2 from both sides
(2p)/2 = (q - 5r)/2
p = (q/2) - (2.5r) is your answer
hope this helps
<u>Answer plus step-to-step explanation:</u>
1. Slope formula = Change in y ÷ change in x.
i.e slope(m) = (Δ means change in)
2. Slope-intercept form is representing equation of a straight line on cartesian plane in the form y = mx + c. <em>Where (m) is the slope of that line and c is the y-intercept.</em>
3. Standard form - is writing numbers in the form of number times ten to power of an exponent. This is also referred to as scientific notation form.
<u>Example:</u>
To write 512 in standard form would be 5.12 × 10²
Answer:
x = - 8
Step-by-step explanation:
To find the zero, let y = 0 in the equation and solve for x
- 4x - 12(0) = 32 , that is
- 4x = 32 ( divide both sides by - 4 )
x = - 8
tan (π/6) + sin (5π/3) . cos (- 3π/4)
= tan 30° + sin 300° . cos (- 135°)
= tan 30° + sin (360° - 60°) . cos 135°
= tan 30° + (- sin 60°) . cos (180° - 45°)
= tan 30° + (- sin 60°) . (- cos 45°)
= tan 30° + sin 60° . cos 45°
= (1/3)√3 + (1/2)√3 . (1/2)√2
= (1/3)√3 + (1/4)√6
= (4/12)√3 + (3/12)√6
= (4√3 + 3√6)/12
