4a - 5 = 11<br> Solve this please
d1i1m1o1n [39]

Answer:

a = 4

Step-by-step explanation:

Given equation:

4a - 5 = 11

Add 5 to both sides:

⇒ 4a - 5 + 5 = 11 + 5

⇒ 4a = 16

Divide both sides by 4:

⇒ 4a ÷ 4 = 16 ÷ 4

⇒ a = 4

Q2) If z is directly proportional to x and z = 12 when x = 3, find the value of x when z = 18.
LenKa [72]

Answer:

4.5

Step-by-step explanation:

→ Set up the direct proportion equation

z = kx

→ Substitute in the values

12 = 3k

→ Divide both sides by 3 to isolate k

4 = k

→ Substitute the value of k back into the original direct proportion equation

z = 4x

→ Substitute the value of z in

18 = 4x

→ Divide both sides by 4 to isolate x

4.5 = x
