4+5(p-1) how to expand brackets and then simplify
Valentin [98]

Step-by-step explanation:

these are multiplications.

you could also write

4 + 5×(p - 1)

now, we need to calculate the contents of brackets (if we can), then do the multiplications and divisions, before we can do the then remaining additions and subtractions.

if we cannot do a calculation directly (because there is a variable involved), we need to do and document the single steps for the individual parts involved.

so,

4 + 5×(p - 1) = 4 + 5×p + 5×-1 = 4 + 5p - 5 = 5p - 1

remember, a multiplication of 2 expressions is done by multiplying every term of one expression with every term of the other expression and adding the results up (by considering their individual signs, of course).

Leah knit a scarf that is 130 centimeters long, Theo knit a scarf that is 4/3 as long
Delvig [45]

Answer: Theo's scarf is  173 + 1/3 centimeters long.

Step-by-step explanation:

The scarf of Leah is 130 centimeters long.

The one of Theo is 4/3 as long as the one of Leah, then we have that the length of the scarf of Theo is:

Lenght = (4/3)*130 cm =(4*130)/3 cm =520/3 cm  

Now, we know that if all the digits of a number add up to a multiple of 3, that number is divisible by 3.

520/3 = (519 + 1)/3 = 519/3 + 1/3 = 173 + 1/3

Theo's scarf is  173 + 1/3 centimeters long.
