<em><u>Question:</u></em>

A man left #5720 to be shared among his son and 3 daughters each daughter shared 3/4 of the Son shared, how much did the son received

<em><u>Answer:</u></em>

The son share was $ 1760

<em><u>Solution:</u></em>

Given that,

$ 5720 is to be shared among his son and 3 daughters

Since each of the three daughters got a share that was 3/4 of the son's share,

Let the son's share by 4x and each daughter's share by 3x

Therefore,

4x + 3 daughters ( 3x ) = 5720

4x + 9x = 5720

13x = 5720

Divide both sides by 13

x = 440

Therefore,

Son share = 4x = 4(440) = 1760

Thus the son share was $ 1760

bulgar [2K]
The answer is like this!

the total number of marbles all together is 25, so that would be the denominator.

blue: 6/25- simplified= already in simplified form
red:10/25- simplified= 2/5
green:9/25- simplified= already in simplified form

so the answer to your question is 2/5.

hope this helped!!

(PLEASE HELP!!) Use the following diagram to answer the questions.
monitta

Answer:

x:

5x - 29 = 3x+ 19

2x = 48

x = 24°

Angle 1:

180 - (3x+7) = 180 - 79 = 101°

Angle 2:

3x + 7 = 79°

Angle 3:

Same as Angle 1 = 101°

Angle 4:

Same as Angle 1 = 101°

Angle 5:

Same as Angle 2 = 79°

Angle 6:

Same as Angle 5 = 79°

Angle 7:

180 - (5x - 29) = 180 - 91 = 89°

Angle 8:

Same as Angle 7 = 89°

Angles 2 and 3 are Supplementary angles

PLZ HELP! A train averages a speed of 90 miles per hour across the plains and 37.5 miles per hour through the mountains. If a tr
Kruka [31]

Answer:

3.8

Step-by-step explanation:

A train averages a speed of 90 miles per hour across the plains and 37.5 miles per hour through the mountains.

If a trip of 300 miles took 3 hour and 48 minutes, how much of it was through the mountains?

Let d = distance traveled at 37.5 (thru the mountains)

then

(300-d) = distance traveled at 90 mph

Write a time equation, time = dist/speed

change 3 hr 48 min to hrs: 3 + 48/60 = 3.8 hrs

plain time + mountain time = 3.8 hrs

%28300-d%29%2F90 + d%2F37.5 = 3.8

Multiply 90*37.5

3375*%28300-d%29%2F90 + 3375*d%2F37.5 = 3.8(3375)

cancel the denominator

37.5(300-d) + 90d = 12825

11250 - 37.5d + 90d = 12825

52.5d = 1575

d = 1575/52.5

d = 30 mi thru the mountains

Check this, find the distance on the plain

300-30 = 270 mi

Find the actual time at each speed

270/90 = 3 hrs

30/37.5 = .8 hrs

-----------------

total time: 3.8 hrs

Factor completely 5ax2 − 20x3 2a − 8x. (a 4x)(5x2 2) (a 4x)(5x2 − 2) (a − 4x)(5x2 2) (a − 4x)(5x2 − 2).
antiseptic1488 [7]

The complete factor of the polynomial 5ax² − 20x³ + 2a − 8x is (5x² + 2) (y − 4x). Then the correct option is C.

<h3>What is polynomial?</h3>

Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.

Factor completely 5ax² − 20x³ + 2a − 8x.

Take 5x² common from the first two terms and 2 from the last two terms. we have

5ax² − 20x³ + 2a − 8x

5x²(a − 4x) + 2 (a − 4x)

Take (a - 4) common, then we have

(5x² + 2) (y − 4x)

The complete factor of the polynomial 5ax² − 20x³ + 2a − 8x is (5x² + 2) (y − 4x). Then the correct option is C.
