Wha rid the value of n very confused and need help

Slav-nsk [51]

Answer:

n = 6

Step-by-step explanation:

Two intersecting chords. The product of the parts of one chord is equal to the product of the parts of the other chord, that is

7(n + 4) = 5(n + 8) ← distribute parenthesis on both sides

7n + 28 = 5n + 40 ( subtract 5n from both sides )

2n + 28 = 40 ( subtract 28 from both sides )

2n = 12 ( divide both sides by 2 )

n = 6

Su has 5 times as many marbles as Bertha. When Su gives Bertha 10 marbles, they have the same amount. How many marbles did they

Dafna11 [192]

Answer:

Part A)

The number of marbles that Su has at the beginning is $25$

The number of marbles that Bertha has at the beginning is $5$

Part B)

The number of marbles that Su has at the end is $15$

The number of marbles that Bertha has at the end is $15$

Step-by-step explanation:

Let

x------> number of marbles that Su has at the beginning

y------> number of marbles that Bertha has at the beginning

we know that

$x=5y$ ----> equation A

$x-10=y+10$ ----> equation B

substitute equation A in equation B

$(5y)-10=y+10$

$4y=20$

$y=5$

Find the value of x

$x=5(5)=25$

Part A) How many marbles did they EACH have at the begining?

The number of marbles that Su has at the beginning is $25$

The number of marbles that Bertha has at the beginning is $5$

Part B) How many did they EACH have at the end?

$x-10=y+10$

$25-10=5+10$

$15=15$

therefore

The number of marbles that Su has at the end is $15$

The number of marbles that Bertha has at the end is $15$
