HELP ITS MATH U CAN DO IT!!!!!!!!!!!!!!!!!!!!!!!!!

Hey There!!

Simplify the following:

2 (-20)+3 (5/4 (-20))+5×2/5×50+4×50

5/4 (-20) = (5 (-20))/4:

2 (-20)+3×(5 (-20))/4+5×2/5×50+4×50

2/5×50 = (2×50)/5:

2 (-20)+3×(5 (-20))/4+5×(2×50)/5+4×50

3×(5 (-20))/4 = (5 (-20) 3)/4:

2 (-20)+(5 (-20) 3)/4+5×(2×50)/5+4×50

5×(2×50)/5 = (2×50×5)/5:

2 (-20)+(5 (-20) 3)/4+(2×50×5)/5+4×50

(-20)/4 = (4 (-5))/4 = -5:

2 (-20)+5×-5×3+(2×50×5)/5+4×50

(2×50×5)/5 = 5/5×2×50 = 2×50:

2 (-20)+5 (-5) 3+2×50+4×50

2 (-20)  =  -40:

-40+5 (-5) 3+2×50+4×50

5 (-5)  =  -25:

-40+-25×3+2×50+4×50

-25×3  =  -75:

-40+-75+2×50+4×50

2×50  =  100:

-40-75+100+4×50

4×50  =  200:

-40-75+100+200

-40-75+100+200 = (100+200)-(40+75):

(100+200)-(40+75)

300-(40+75)

300-115

Answer:

Rectangle's is 28

Step-by-step explanation:

We multiply 9 * 4 to get rectangless shape and then we substract squares (2) shape 2*2*2

(9*4) - (2*2*2)= 28

Answer: 460.93

Step-by-step explanation:  k − 187.25 = 273.68.

This is a one-step equation, solving this is simple. you want to change the - to + and add on both sides

k − 187.25 = 273.68.

   + 187.25     +187.25

k=460.93

That would be 424.93, hope this helps.

Answer: The evaluated answer is 8. The coefficient is 6. The variable is y. The constant is 5.

Step-by-step explanation for the evaluated answer: Just substitute 1/2 for y. You should get 6x1/2+5. Then, multiply the 6 and the 1/2 and you should get 6/2+5. 6/2 can be simplified to 3 and then you just need to add the five to get 3+5=8. S your final answer should be 8. Hope this helps!

Answer:

5/18

Step-by-step explanation:

We have 2 things to consider here, rolling two identical numbers, or rolling a sum of 8

Rolling two identical numbers

To make this simple, think about how many possibilities there are to have two identical numbers. (1,1) (2,2) (3,3) (4,4) (5,5) (6,6). The total amount of possibilities for rolling two dice is 6*6 which is 36. That would be 6/36 which is 1/6

Rolling a sum of 8

The numbers which add up to 8 are, (2,6)(3,5)(4,4)(5,3)(6,2). With 36 total possibilities, it would be 5/36.

However, we can see, (4,4) is repeated, so we have to subtract 1/36.

Answer

1/6 + 5/36 - 1/36

6/36 + 5/36 - 1/36

10/36

5/18

Answer:

5/18

Step-by-step explanation:

1) Find the Greatest Common Factor (GCF).

GCF = q

2) Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)

\(q(\frac{3q}{q} +\frac{-5qr}{q} +\frac{4pq}{q} )\)

3) \(q(3-5r+4p)\)

Answer:

for row one put 1/2 the numbers. for row 2 put 3/4 of the numbers. row 3 put 1/4 of the numbers.

Good evening,

Answer: A = (8;6)

Step-by-step explanation: Point A is located on the value 8 on the abscissa and 6 on the ordinate. We note the point being equal to the number of the abscissa axis on which it is located then the one of the ordinate axis such as A = (8;6)

Answer:

16 pieces

Step-by-step explanation:

The total length of ribbon cut off from the 20 pieces is 8*20 because each piece is equal to 8. 8*20=160

The amount of ribbon left afterwards is 400-160 which is equal to 240.

We can do 240 divided by 15 to see how many pieces that we can cut. 240/15=16

decimal form- 0.1

Step-by-step explanation:

Answer:

Volume = 66

Surface are = 144

Step-by-step explanation:

1. Volume

The formula to find the volume of a triangular prism is the following,

\(A=\frac{l*w*h}{2}\)

The following information is given,

lenght = 4

width = 11

hieght = 3

Substitute these numbers into the formula and solve for the heihgt,

\(A=\frac{l*w*h}{2}\\\\A=\frac{4*11*3}{2}\\\\A=66\)

2.Surface area

The surface area of a figure is the two-dimensional distance around the figure. It can be found by finding the area of each face of the figure and then adding the result up.

The formula to find the area of a rectangle is the following,

\(A_r=(lenght)(width)\)

The formula to find the area of a triangle is the following,

\(A_t=\frac{(legnth)(width)}{2}\)

Substitute in the give values and add up the results to find the total surface area of the rectangle,

\(((5)(11))+((4)(11))+((3)(11))+(\frac{(3)(4)}{2})+(\frac{(3)(4)}{2})\\\\=55 + 44 + 33+ 6 + 6\\\\= 144\)

Work backwards

x*5-3 = 42

x*5 = 45

x = 9

Answer:

t can be 12 or 16

Step-by-step explanation:

8> 3+ t/4

meaning that 3+t/4 must be less than 8

so t can be 12 or 16, as 12/4=3 and 16/4=4 and when added to 3, we get 8>6 and 8>7

Answer:

c. 2/13

Step-by-step explanation:

The bag starts with 8 red marbles, 4 green marbles, and 2 yellow marbles. Since he draws a red marble from the bag and does not replace it, there will be one less marble.

So now there are 7 red marbles, 4 green marbles, and 2 yellow marbles. Add the number of marbles together and then find the probability of drawing a yellow marble.

7+4+2 = 13

2/13

So the probability of Bill drawing a yellow marble would be 2/13.
