Use the terms 4, 12a 6 2a and 24 to make equivalent expressions use each term only once use substitution to prove that the expre
Vanyuwa [196]

Answer:

12a + 24 = 6(2a + 4)

Step-by-step explanation:

Given the numbers :

4, 12a 6 2a and 24 ; create an equivalent expression :

12a, 2a, 4, 6, 24

We could separate tbe constant terms and those with variables :

12a, 2a ; 6, 4, 24

We could put the larger digit to one side

12a + 24 = 6(2a + 4)

This way the Right hand side is equal to the left hand side.

Check:

12a + 24 = 6(2a + 4)

12a + 24 = 12a + 24

Hence, the proof

Given that y is directly proportional to x. If y = 30 and x= 5, write an equation that connects y with x.
alukav5142 [94]

Answer: y = 6x

Step-by-step explanation:

Since this is a direct proportion, we will introduce the constant of proportionality here and this will be:

y = kx

Since y = 30 and x= 5,

30 = 5 × k

30 = 5k

k = 30/5

k = 6

Therefore, the equation that connects y to x will be:

y = kx

y = 6x

The equation that connects y to x is y = 6x.
