Frida started to solve the equation 3x = 36 by adding 3 to both sides. Explain why Friday’s method will not solve the equation.
vlada-n [284]

Explanation:

The equation is 3x=36

Frida started to solve the equation by adding 3 to both sides.

Thus, the equation becomes,

3x+3=39

This will not solve the equation.

To solve the equation 3x=36, we need to divide both sides of the equation by 3.

Thus, the equation becomes,

\frac{3x}{3} =\frac{36}{3}

Dividing we get,

x=12

Hence, Frida cannot solve the equation by adding 3 to both sides of the equation. To solve the equation, Frida needs to divide both sides of the equation by 3.

Thus, to solve the equation 3x=36 Frida needs to divide both sides of the equation by 3.

Today, 6 friends went out for lunch. Their total bill was $27.60, including tax and gratuity. They decided to split the bill equ
Paladinen [302]

Step-by-step explanation:

Right, okay, so this is a bit of a weird one. Let's go step by step.

"Today, 6 friends went out for lunch." = The number 6 is gonna be in our equation somewhere.

"Their total bill was $27.60" = so is the number 27.6

"They decided to split the bill equally" = 27.6 "split equally" (aka divided by) 6 friends is 4.6

"each paid with a $10 bill" = This is where it gets a lil weird. So, if they divided the bill among them, none of their amounts are gonna be anywhere near ten dollars. This is one of those questions that wouldn't really happen in real life. People would probably use fives instead, but whatever. So a number we'll be using for something is 10.

"How much money will each person get back?" = So we have to find the amount they all paid (10) minus the amount each one had to pay (4.6).

To put it all into a full equation...

10 - ( 27.6 / 6 )

Divide.

10 - 4.6

Subtract.

5.4

Put back into money form.

$5.40

Answer:

Each person will get back $5.40.
