Solve this system of equations by using the elimination method -3x+y=6 -3x+y=12

xxMikexx [17]

Answer:

None

Step-by-step explanation:

We can eliminate the x's by add the 2 equations :

2y = 18

Divide both sides by 2 :

y = 9

Substitute this value into equation 1 to solve for x :

-3x + (9) = 6

Subtract 9 from both sides :

-3x = -3

Divide both sides by -3 :

x = 1

Substitute these values into equation 2 to check :

-3(1) + 6 = 12 ❌❌

So it has no solution

In his stamp album, Jamal has 4 new stamps and 6 used stamps. Which ratio can be represented by three fifths ?

SashulF [63]

Answer:

The ratio of used stamps and total stamps can be represented by three fifths.

Step-by-step explanation:

It is give that Jamal has 4 new stamps and 6 used stamps.

New stamps = 4

Used stamps = 6

Total stamps = New stamps + Used stamps = 4 + 6 = 10

We need to find the ratio that can be represented by three fifths

$\dfrac{\text{New stamps}}{\text{Used stamps}}=\dfrac{4}{6}=\dfrac{2}{3}$

$\dfrac{\text{New stamps}}{\text{Total stamps}}=\dfrac{4}{10}=\dfrac{2}{5}$

$\dfrac{\text{Used stamps}}{\text{Total stamps}}=\dfrac{6}{10}=\dfrac{3}{5}$

Therefore, the ratio of used stamps and total stamps can be represented by three fifths.
