5 - 3(a + 6) = a - 1 + 8a

Step-by-step explanation:

a = -1

Step-by-step explanation:

Using PEMDAS, we should distribute the 3 before doing anything else, and then solve the equation like normal.

5 - 3a - 18 = a - 1 + 8a (PEMDAS)

-13 = 4a -1 + 8a (-18 +5 = 13)(3a + a = 4a)

-12 = 12a (-13 + 1 = -12)

a = -1 (12/-12 = -1)

a. 3/4 ÷ 1/8 = 6

step-by-step explanation:

in the question, the number line represents 3/4 divided into 6 equal units. each arrow represents a unit and there are a total of six arrows.

the size of each unit is 1/8 as shown.

showing that 1/8 divides 3/4 into 6 divisions:

3/4 ÷ 1/8

= 3/4 x 8/1

= 3/1 x 8/4

= 3 x 2

= 6

hence, the number line represents six divisions given by 3/4 ÷ 1/8.
