Write the converse of the following statement and determine its truth value.
"If a class has 3 left-handed people and 24 right-handed people, then the ratio of lefties to righties is 1:8"

Answer:

The probability is 1/4, give me brainliest answer

The step by step solution to this is very simple, There are two "A" spots on the wheel and 8 spots all together. 2/8= 1/4= 25%

Answer: 3/5

Step-by-step explanation:  

The probability of spinning a one can be written as a fraction. One out of five sections contain a '1' and so, the probability of spinning a one is 1 / 5 . Because 1 is less than half of 5, this outcome can be described as unlikely. The probability of spinning a two is 3 / 5.

Answer: 6x+3y=12

x=-1/2y+2

Step-by-step explanation:

step 1: add -3y to both sides

6x+3y+-3y=12+-3y

6x=-3y+12

step 2: divide both sides by 6

6x/6=-3y+12/6

Answer:

y = 6 and x = -1.

Step-by-step explanation:

It's normally useful for me to rewrite the equation so they match. I'm using the substitution method.

First find out what "y" equals (I'm using the second equation):

Add 8 to both sides:

y - 8 = 2x

  +8    +8

y = 2x + 8

Plug this into the previous equation.

6x + 3(2x + 8) = 12

Distribute first:

3(2x + 8)

3 * 2x = 6x

3 * 8 = 24

6x + 24

Rewrite the equation:

6x + 6x + 24 = 12

Find liked terms.

6x + 6x + 24 = 12

They are liked terms so combined them: 6x + 6x = 12x.

Rewrite the equation again:

12x + 24 = 12

Solve for "x".

Subtract 24 on both sides.

12x + 24 = 12

      -24   -24

12x = -12

Divide 12 to get x by itself.

12x = -12

    12

x = -1

Plug x into the second equation to find y.

y - 8 = 2(-1)

y - 8 = -2

Add 8 to both sides.

y - 8 = -2

  +8   +8

  y = 6

The answers are y = 6 and x = -1.

used to hold other items, so it is helpful to know the volume of the box helpful to know the volume of the box.

The volume of the box is V = l × w × h, where l, w, and h are the length, width, and height of the cuboidal box.

A closed three-dimensional geometric shape called a cuboid is surrounded by six rectangular plane sections.

Given a shoe box.

The shape of a shoe box is a cuboid.

Let the length, width, and height of the cuboid be l,w, and h, then the volume of the cuboid is:
V = l × w × h

Hence, the volume of the box is V = l × w × h, where l, w, and h are the length, width, and height of the cuboidal box.

2x + 3y = 26 -- equation 1

3x + 5y =40 -- equation 2

(Equation 1) * 3

6x + 9y = 78 -- equation 3

If Myesha found 6 nickels and 12 quarters under her cushion, this means that she has a total of 18 coins.

An equation is an expression used to show the relationship between two or more variables and numbers.

Let x represent the number of nickels and y represent the number of quarters. There are 2 cups in 1 pint. Hence:

If she has 6 nickels and 12 quarters:

Number of coins = 12 + 6  = 18

If she has x nickels and y quarters:

Number of coins = x + y  

If Myesha has 6 nickels and 12 quarters, this means that she has 18 coins.

Answer:

the answer is B on ed2020

Step-by-step explanation:

for answer b, if you subtract 330 from 510 you get soda = 180 cal. then if you subtract 110 from 370 you get 260, and 260 divided by two (he consumed 2 juice) equals 130.

so you have soda = 180 cal and juice = 130 cal

if you plug it into joe's calorie intake you do 130 (1 serving of juice) + 180 (1 serving of soda) and + 220 (two servings of milk) you get 530 which is joe's total calorie intake in liquids, so B (110) is correct

Using matrices to solve, the number of calories that are in 1 serving of milk is; 110 Calories

Let the calories in one serving of milk be x

Let the calories in one serving of juice be y

Let the calories in one serving of soda be z

Thus, for Joe, equation to show amount of calories is;;

2x + y + z = 530    -----(1)

For Darius, equation to show amount of calories is; ;

x + 2y = 370     ------(2)

For Marian, equation to show amount of calories is;

3x + z = 510    ------(3)

Using matrix calculator online to calculate this 3 equations, we have;

x = 110 calories.
