Solve 12 3/8 divided by 5 1/2 Please explain :)

Mathematics
2 answers:
Eddi Din [679]3 years ago

Answer:

Below.

Step-by-step explanation:

The problem would look like this:

12 3/8 / 5 1/2

My math teacher told us to write it like a normal division problem.

12 3/8 ÷ 5 1/2

One way to solve is to turn both fractions into improper fractions, so..

12 3/8

So multiply 8 x 12 = 96 + 3 = 99/8

Then, 5 1/2, 2 x 5 = 10 + 1 = 11/2

99/8 ÷ 11/2, 99 ÷ 11 = 9, 8 ÷ 2 = 4,

So your answer would be 9/4, which is an improper fraction. To simply, just divide 9 by 4, and you would get 2 1/4 (mixed number).

Answer:9/4

Step-by-step explanation:

99/8*2/11=9/4*1/1=9/4

You can cancel out 99 and 11 to 9 and 1 as they are multiples of eac hother and you can do the same for 8 and 2 to 4 and 1

Answer:

equation of the line is y=x+1

Step-by-step explanation:

the equation of a line has the form y = mx + b

while m is for the slope and b is for the y-intercept.

you can see from the graph that the line intercepts the y-axis at y=1 this is the b.

you can get the slope of the graph by taking two points from the graph lets say (1, 2) and (3, 4) then using this formula:

<h2>m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }</h2>

in our case it will be:

m=\frac{4-2}{3-1} = \frac{2}{2}=1

then just substitute the values for m and b.

What is a two variable linear equation
True [87]

Answer: Linear equations in two variables. If a, b, and r are real numbers (and if a and b are not both equal to 0) then ax+by = r is called a linear equation in two variables. (The “two variables” are the x and the y.) The numbers a and b are called the coefficients of the equation ax+by = r.

Answer:

  • ∠QSR = 78°
  • ∠SQR = 51°

Step-by-step explanation:

The measure of an inscribed angle (QTR) is half the measure of the arc it intercepts. The measure of an arc is the same as the measure of the central angle it intercepts. So, we have ...

  ∠QSR = 2×∠QTR

  ∠QSR = 2×39°

  ∠QSR = 78°

__

Sides SQ and SR are radii of circle S, so are the same length. That means triangle QRS is an isosceles triangle and the base angles SQR and SRQ are congruent. The sum of angles in a triangle is 180°, so we have ...

  ∠QSR + 2(∠SQR) = 180°

  78° + 2(∠SQR) = 180° . . . . fill in the value we know

  2(∠SQR) = 102° . . . . . . . . . subtract 78°

  ∠SQR = 51° . . . . . . . . . . . . .divide by 2

Find the missing part. L=8, w=4, h=2. Find the diagonal of (d) of the retangular solid
marusya05 [52]

The diagonal of the rectangular solid is d=2 \sqrt{21}

Explanation:

The length of the rectangular solid is l=8

The width of the rectangular solid is w=4

The height of the rectangular solid is h=2

We need to determine the diagonal of the rectangular solid.

The diagonal of the rectangular solid can be determined using the formula,

d=\sqrt{l^{2}+w^{2}+h^{2}}

Substituting the values l=8, w=4 and h=2 , we get,

d=\sqrt{8^{2}+4^{2}+2^{2}}

Squaring the terms, we get,

d=\sqrt{64+16+4}

Adding the terms, we have,

d=\sqrt{84}

Simplifying, we have,

d=2 \sqrt{21}

Thus, the diagonal of the rectangular solid is d=2 \sqrt{21}

Use elimination to solve each system.
Cerrena [4.2K]

Answer:

$3 and $2

Step-by-step explanation:

let p represent popcorn and d drinks , then

2p + 3d = 12 → (1)

3p + 5d = 19 → (2)

multiplying (1) by 3 and (2) by - 2 and adding will eliminate p

6p + 9d = 36 → (3)

- 6p - 10d = - 38 → (4)

add (3) and (4) term by term to eliminate p

0 - d = - 2

- d = - 2 ( multiply both sides by - 1 )

d = 2

substitute d = 2 into either of the 2 equations and solve for p

substituting into (1)

2p + 3(2) = 12

2p + 6 = 12 ( subtract 6 from both sides )

2p = 6 ( divide both sides by 2 )

p = 3

Popcorn costs $3 and a drink costs $2
