Julie started with 20 pieces of gum and gave away x pieces. Conrad started with 35 pieces of gum and gave away twice as many pieces as Julie did.

How many pieces of gum did Julie give away if they had the same number of pieces of gum left?

Answers

Answer:

15

Step-by-step explanation:

See picture

Julie gave away 15 pieces.

I found my answer by making an equation. For Julies half, we do 20-x because we don't know how many pieces she gave away but we do know how many pieces she started with. For Conrads half, we do 35-2x because we know he started out with 35 pieces and gave away two times how much Julie gave away so 2x. Then because we want them to have the same amount of gum left we set their two halves as equal to eachother.

So our equation is 20-x=35-2x. Then we solve:

20-x=35-2x (then we subtract 20 from both sides to move it right)

-x=15-2x (then we add 2x to both sides to move it left)

x=15 (and here is out answer)

Each piece of the Three-fourths bar can be divided into 3 pieces, and each piece of the One-third bar can be divided into 4 pieces.

Step-by-step explanation:

If each piece of the Three-fourths bar is divided into 3 pieces,then you will get total pieces of 12.

In the same way, when each piece of the One-third bar is divided into 4 pieces, total pieces is 12.

After this we can subtract

Can someone explain how to solve 3/4 + 7/8 + 1/2 as a mixed number in simplest form

Answers

Answer: What you hav to do is to simplify. That’s obvious so let me explain better.

Step-by-step explanation:

3/4 in its simplist form would be 1 1/4 because how many times does three go into four? Only once so it’s 1 and 1/4. Then you repeat this process. 7/8, 1 1/8

btw I hope I, right cuz I’m not the best at math..... sorry if I got it wrong ;-;

it’s 2 1/8 bc 3/4 is equal to 6/8, 7/8 stays, and 1/2 is equal to 4/8. You just add all of those for a total of 17/8. 8•2=16 with one leftover. 2 1/8.

Answers

Starting with the "plus two" first, I'll subtract two from either side of the equation. Only then will I divide through by the seven. My work looks like this:

7x + 2 = -54

   -2    -2

------------

7x     = -56

--       ---

7         7

x     =  -8

By doing the plus / minus first, I avoided fractions. As you can see, the answer doesn't involve fractions, so I did myself a favor by doing the dividing-through last. My solution is:

x = –8

Plus 2 x 5 is your answer

Answer:: A.) There are 15 full squares and 14 partial squares. It is not easy to count the partial squares. The top part has 6 half squares. They add up to 3. The partial squares at the bottom add up to 4. All together there are 42 full squares.

B.) there are two shapes: a right triangle at the top and a parallelogram at the bottom.

C.) The formula for the area of a triangle is A= bh/2. The Area of a parallelogram is A= bh.

D.) Using formulae-- A = 6×6/2

For the triangle part area is 18. For the parallelogram A = 6×4

That is 24. Adding the two shapes together, 18+24=42

(a) True

(b)False

(c) True

What is an linear equation in two variable ?

An linear equation in two variable is an statement that compares two linear expression in two variables using equal to sign.

Let x and y be two variables then the linear equation in these two variable in standard form is ax+ by+ c = 0 , where a, b, c are constants.

Given, the equation y-555 = -22(x-12) represents y as a function of x , where y is the number of Lego pieces Jefferson has left to build and x is the number of minutes he has been building. When x = 0 means that Jefferson has not started building the Lego therefore  y = all Lego pieces

y-555 = -22(0-12)

⇒y -555 = 22*12

⇒ y = 555 +264 = 819

It means that total Lego pieces were 819 not 555

Therefore, (b) statement is false.

Simplify:     y-555 = -22(x-12)

⇒ y-555 = -22x + (22*12)

⇒ y- 555 = -22x +264

⇒ y = - 22x +264 +555

y = -22x +819

Therefore , this situation can be represented by  y = -22x +819

Thus , (c) statement is true

Also, from this relation ship we can see that initially there were 819 Lego pieces and when x =1 , y = 819 -22, when x=2 then y =819 - 2(22)

and so on .This means that every minute Jefferson removes 22 Lego pieces from box to assemble X- wing.

Thus (a) is an true statement.

Therefore, by solving the equation y-555 = -22(0-12), we got that statement (a) and (c) are true and (b) is false.
