A nutrition label shows that there are 75 milligrams of sodium in every 12 crackers. You eat 21 crackers. How much sodium do you consume?

Answers

78.36 milligrams. If I calculated correctly... 12 is 16% of 75. Therefore 16% of 12 is 3.36. So 75+3.36=78.36

The amount of sodium that you consume is 131.25mg.

Using this formula

Amount of sodium=(Milligrams of sodium/Number of crackers)×Number of cracker consumed

Where:

Milligrams of sodium=75 milligramsNumber of crackers=12 crackersNumber of cracker consumed=21 crackers

Let plug in the formula

Amount of sodium=(75mg/12)×21

Amount of sodium=6.25mg×21

Amount of sodium=131.25 mg

Inconclusion  the amount of sodium that you consume is 131.25mg.

Suppose y is directly proportional to x. If y= 24 when x=2, what is the value of x when y= 144?

Answers

Answer:

12

Step-by-step explanation:

Because y=24 and x=2 you do the following:

144/24=6

Then, 6x2=12 because it is proportional

y= -32

Step-by-step explanation:

step 1: from the first equation you will make X the subject of formula, the equation then becomes;

X= 4-y

step 2: substitute X in the second equation, the equation then becomes 5 * [4-y] + 3y = -6

The answer is r=-9

Answer: 4.5

Step-by-step explains:  1) 2r - 9 = -18

                                          2r - 9 + 9 = -18 + 9

                     2)  ( 9 + 9 )      Add the numbers

                       ( -18 + 9 )    add the numbers

                                            2r = -9

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as D

Now , the value of D is

Substituting the values in the equation , we get

Let the total distance ran by Johnny be D = ran 2 miles north, 6 miles west, 3 miles north, 10 miles south, 8 miles east, and then 2 miles

So , D = 2 + 6 + 3 + 10 + 8 + 2

On simplifying the equation , we get

D = 31 miles

Hence , the distance is D = 31 miles

What value of x makes the equation below true? −2x=−36 A x=−34 B x=−38 C x=−18 D x=18

Answers

Answer:

D x = 18

Step-by-step explanation:

Given equation:

−2x = −36

Divide both sides by -2 to find x

−2x / -2 = −36 / -2

x = −36 / -2

x = 18

x = 18 makes the equation −2x = −36 true

However, the role of Paul McCartney is often overlooked. John Lennon and Paul McCartney were in other bands together before the forming of the Beatles. In 1962, along with Ringo Starr and George Harrison, they formed the rock group known as "The Beatles." The group featured a modern rock that was new and popular during the period with John and Paul composing and doing the leads on most of the songs. They were backed by George on lead guitar and Ringo on drums. George and Ringo also assisted on backing vocals. When they first began playing, the main influence inside the band was John Lennon, who had an ability to compose songs at a moment's notice with an inspiration that others missed. He pushed the members of the band during their touring years and was able to achieve the best possible results from the group. However, McCartney was also a strong force in the group since Lennon many times asked for McCartney's advice about ideas for songs. McCartney wrote many of the group's biggest hit songs, and often, he didn't even ask for song writing credit. After the breakup, McCartney launched a successful solo career. He has released many recordings both in the United States and abroad. One accomplishment was his first classical piece, Liverpool Oratorio, which is no small feat considering that McCartney never learned to read music.Which text would most likely follow the same text structure as the passage?
