PLS HELP IM FAILING MATH!

oksano4ka [1.4K]

Answer:

1. Never true

2. Never true

3. Bad question! Typo? (see discussion below)

4. Always true

5. Always false

Step-by-step explanation:

1. x - 13 = x + 1. Subtract x from both sides of the equation, and you get -13 = 1. False! (Never true!)

2. x + 1/2 = x - 1/2. Subtract x from both sides: 1/2 = - 1/2. False! (Never true!)

3. This one's weird, with two equal signs. That's not unusual; multiple equal signs are often used when a chain of equalities is being displayed. For instance, you can write (3)(2x + 5) = (3)(2x) + (3)(5) = 6x + 15. That's an example of the Distributive Property--the 3 is multiplied by both of the terms inside parentheses (shown after the first equal sign), then actually doing those multiplications produces the expression after the second equal sign.

OK! This question says 2(x + 3) = 5x = 6 - 3x. Take it in two parts.

a. 2(x + 3) = 5x Distribute the 2.

2x + 6 = 5x Now subtract 2x from both sides.

6 = 3x Divide both sides by 3.

2 = x So that first part is true only when x = 2. Gaa! That's not one of your answer choices. Now, check out the second part

b. 5x = 6 - 3x Add 3x to both sides.

8x = 6 Divide by 8

x = 6/8 = 3/4

It doesn't help to use the first and third expressions, either.

2(x + 3) = 6 - 3x Distribute the 2

2x + 6 = 6 - 3x Add 3x.

5x + 6 = 6 Subtract 6.

5x = 0 Divide by 5

x = 0

None of these is always false. None of these is always true.

4. x - 3 = 2x - 3 - x Simplify the right side by combining the x terms.

x - 3 = x - 3 Aha! Same expression on both sides! Always true

5. 3(x - 5) = 2(x - 5) + x Distribute the 3. Distribute the 2.

3x - 15 = 2x - 10 + x Combine the x terms on the right.

3x - 15 = 3x - 10 Subtract 3x

-15 = -10 (Always false!)

A company donates 2,292 gifts to a school. the gifts are diveded evenly among 19 classrooms. The rest of the gifts are given to

BARSIC [14]

Answer:

Each classroom received 120 gifts and the hospital received 12 gifts

Step-by-step explanation:

Division As Evenly Distribution

The first concept we manage when learning about divisions is how to distribute an amount N among m elements such as everyone receives the same amount.

If the nature of the problem allows distributing decimal portions of N, then every receiver gets exactly the same amount N/m.

But things are different when the division must be an integer number. For example, if we wanted to divide gifts, we cannot give partial gifts. So the correct division is a matter of the study of integer numbers.

If N is divisible by m, i.e. there is no remainder in the division, then each element will receive N/m gifts. But what if they are not divisible? We must divide and take the integer part of the division and discard the remainder

We want to divide 2,292 gifts to the school, where there are 19 classrooms. If we divide 2,292/19 we get 120 and a remainder of 12.

Answer. Each classroom received 120 gifts and the hospital received 12 gifts

Zachary's final project for a collage course took a semester to write and had 95,234 words. Zachary wrote 35,295 words he first

Nina [5.8K]

Okay so I don't know what you're trying to find out here, but if you're trying to find out how many words he has left after writing those two months, all you have to do is add. 35, 295 + 19, 240 and should get 54, 535. Then you subtract 95,234 - 54,535 and get 40,699.. So Zachary has 40,699 words left to write
