a)42

b) triangle and Parallelogram

c) for triangle: (base× height)÷2

for Parallelogram: (base×height)

d) triangle: (6×6)÷2=18

Parallelogram: 6×4=24

18+24=42

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

Answer:

72

Step-by-step explanation:

If we make -10 4/5 a fraction: -54/5

If we make -6 2/3 a fraction: -20/3

So that's -54/5 × -20/3 (Minus Multiplied by Minus is Plus)

That is 72

the points do not form a line or a parabola

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 ;-;

Eli, because he add 45mL for each 6 ounces 3x2=6 so if you put 20x2 you get 40 which id less than 45 so its Eli's.

Step-by-step explanation:

By solving the equation y-555 = -22(0-12), we got that statements

(a) True

(b)False

(c) True

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.

The complete question can be found below:

Jefferson received a Star Wars X-Wing Lego set for Christmas. 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. Use this information to mark a-c as true or false. If false, rewrite the statement correctly. _

a. Jefferson removes 22 Lego pieces a minute from the box to assemble the X-Wing. _

b. The Lego set contains 555 pieces.

c. This situation can be represented with the equation  y = -22x +819

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)

Answer:

22 2/3

Step-by-step explanation:

Each student has 1 1/3 minutes to speak. There are 17 students.

1 1/3 x 17= 17 17/3

3 goes into 17 5 times and leaves behind 2 and so you combine the 5  and 17 making 22. the 2 left behind remains as the fraction 2/3

22 2/3 is the final answer

Answer:

On the second line, Alice didnt carry the negative in (-8). And for the 3rd line, she did 24 times 1/3, not 24 divided by 1/3.

Step-by-step explanation:

The correct answer would be, -360.

12*(0.25)*(-8)/(1/3)*5

3*(-8)/(1/3)*5

-24/(1/3)*5

-72*5

-360

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

Answer:

C.  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
