What is the value of a in the equation 4a + 3(a + 1) = 24?
2
3
7
21

Option (2) is correct.

a = 3

Step-by-step explanation:

 Given  : equation  4a + 3(a + 1) = 24

We have to solve for a and choose the correct option from the given options.

Consider the given equation  4a + 3(a + 1) = 24

Multiply each term in bracket with 3, we have,

4a + 3a + 3 = 24

Adding 4a and 3a , we have,

7a + 3 = 24

Subtract 3 both sides, we have,

7a + 3 - 3 = 24 - 3

Simplify,

7a= 21

Divide both side by 7, we have,

a = 3

Thus, option (2) is correct.

answer: the 4 kilogram bag

step-by-step explanation: this is because if you divide the number of kilograms into the total it will tell you how much each individual kilogram would be worth. 2 kilos is 7 and change 3 would be around 6 ish and the 4 kilo would be 4.6 and change and the 5 kilos would be like 4.88

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d
