Plzz help me im going to most more like this because im not understanding it
lisov135 [29]
Hi there!

In order to solve, you can use substitution. This means that you use one equation and solve for one variable, then use that one equation and plug it into the other equation. Here's how we'd do it:

WORK:
x = 12 - y (since x is already solved for, we'll use that to plug into the other given equation.
2(12 - y) + 3y = 29 (using substitution)
24 - 2y + 3y = 29
24 + y = 29
y = 5
Plug the value of y back into the first equation
x = 12 - 5
x = 7

ANSWER:
A - x = 7, y = 5

It seems as though you're having some trouble with these questions, PLEASE MESSAGE ME!! I'd be more than happy to help you work through as many problems as you need until you get the hang of it (plus, it doesn't cost you any points!)

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

Caleb bought groceries and paid
lutik1710 [3]

Answer:

Price of Caleb's groceries before tax= $6.4

Step-by-step explanation:

Let price of groceries before tax be = $ x

Sales tax % = 2.5%

Sales tax applied = 2.5\% \ of\ x = \frac{25}{100}\times x = \frac{25}{100} x

Actual sales tax paid = $1.60

∴ \frac{25}{100}x=1.60

Multiplying both sides by 100.

100\times \frac{25}{100}x=1.60\times 100

25x=160

Dividing both sides by 25.

\frac{25x}{25}=\frac{160}{25}

x=6.4

∴ Price of groceries before tax= $6.4
