-5x+6y=-2 and 5x-3y=1 How many solution

Mathematics
1 answer:
hoa [83]2 years ago
7 0

Step-by-step explanation:

Find the values of x and y to determine how many solutions.

Use the elimination method. Add both of the equations.

<u>Sum:</u>

<u />3y=-1

<u>Divide each side by 3:</u>

<u />\boxed{y=-\frac{1}{3}}

<u />

<u>Substitute y = -(1/3) into the first equation:</u>

<u />-5x+6(-\frac{1}{3})=-2

<u>Multiply:</u>

<u />-5x-2=-2

<u>Add 2 to both sides:</u>

-5x = 0

We can determine:

\boxed{x=0}

(0, -1/3)

The system of equations have 1 solution.

9(3)=27+12=39=c

9(4)=36+12=48=c

57=9p+12
-12 -12
45=9p
divide by 9 both sides 45/9=5=p

c=9(6)+12
c=54+12
c=66

a box 12 cm long, 5 cm wide and 12 cm height. A cardboard rectangle is inserted along the diagonal to divide the box vertically
Ipatiy [6.2K]

Answer:

The Cardboard dimensions are 13cm in length and 12cm in breadth

Step-by-step explanation:

We can use Pythagoras Theorem to find the length the Cardboard (a²+b²=c²). Let A be 5 and B be 12, we find that C is equivalent to 13. The height is 12, thus the breadth of the Cardboard is also 12. Hope this helps :)

For a school fund raising project, Aiden and Jacob collected money in the ratio of 3.5 : 6.8. Jacob collected $115.50 more than
user100 [1]
X - the amount of money collected by Aiden
y - the amount of money collected by Jacob

Aiden and Jacob collected money in the ratio of 3.5 : 6.8.
\frac{x}{y}=\frac{3.5}{6.8} \\&#10;6.8x=3.5y \\&#10;x=\frac{3.5}{6.8}y \\ x=\frac{35}{68}y

Jacob collected $115.50 more than Aiden.
x+115.5=y \\&#10;x=y-115.5 \\ \\&#10;x=x \\&#10;\frac{35}{68}y=y-115.5 \\&#10;\frac{35}{68}y-y=-115.5 \\&#10;\frac{35}{68}y-\frac{68}{68}y=-115.5 \\&#10;-\frac{33}{68}y=-115.5 \\&#10;y=-115.5 \times (-\frac{68}{33}) \\&#10;y=238 \\ \\&#10;x=y-115.5=238-115.5=122.5 \\ \\&#10;x+y=238+122.5=360.5

The total amount of money they collected is $360.50.

What is the purpose of preparing a trial balance?
AlladinOne [14]

Answer:

The purpose of a trial balance is to prove that the value of all the debit value balances equals the total of all the credit value balances. If the total of the debit column does not equal the total value of the credit column then this would show that there is an error in the nominal ledger accounts.
