Step-by-step explanation:
f ∝ ghj
Convert the proportion to an equality
f = kghj
Calculate the value of k
18 = k × 4 × 3 × 5
18 = 60k
k = ⅓
Rewrite the equation with the value of k
f = ⅓gkj
Find the new value of f
f =⅓ × 5 × 12 × 3 =
Answer:
-9/10
Step-by-step explanation:
- Find the LCM of 10 and 3: 30
- Alter the numerators to fit the denominators: 3 × 3 = 9, -1 × 10 = -10
- Re-write the fractions: 9/30 ÷ -10/30
- 9/30 ÷ -10/30 = 9/30 × -30/10
- 9/30 × -30/10 = -270/300

Answer:
p < -32
Step-by-step explanation:
<em>Given:</em> p/-8 + 9 > 13
<em>Rewrite:</em> + 9 > 13
<em>Subtract 9 from both sides:</em> > 4
<em>Move the negative (it is a fraction): </em> > 4
<em>Multiply both sides by 8:</em> -p > 32
<em>Times by -1 (-p -> -1p): </em>p > -32
<em>Flip the sign (multiplied by a negative): </em>p < -32
Hope this helps, have a nice day :D
