What is 8.2p-33.4=1.7-3.5p

Answers

$8.2p-33.4=1.7-3.5p$

$8.2p=1.7-3.5p+33.4$    $Add \ 33.4 \ to \ both \ sides$

$8.2p=-3.5p+35.1$

$8.2p+3.5p=35.1$    $Add \ 3.5p \ to \ both \ sides$

$11.7p=35.1$

$(11.7p)/(11.7) = (35.1)/(11.7p)$    $Divide \ both \ sides \ by \ 11.7$

$p=3$    $Solution$

p=3
First you add 33.4 to both sides. Then add 3.5p to both sides. Then divide 35.1 by 11.7 and you get 3.

Can someone help me solve 5(t+2) please

Answers

This is a simple multiplication, written in a strange form.
5(t+2) means 5 x t + 5 x 2 which simplifies to:
5t + 10
If it's equal to a number, 0 for example, then with a little rearranging we can find what t is.
5t + 10 = 0,
5t = -10
t = -2
If it's not equal to something, the answer is just 5t + 10.

What time is 5 3/4 hours after 9:22 pm?

Answers

it would be 3:07 in the morning

9:22 PM + 5h = 2:22AM next day

3/4 h = 45min

1h = 60min

60min - 22min = 38min
45min = 38min + 7min

2:22AM + 45min = 2:22AM + 38min + 7min = 3:00AM + 7min = 3:07AM

Answer: 5 3/4h after 9:22PM is 3:07AM next day.
