Here, Equations are: x - y = 6
y = x - 4
x - y = 4

Here, we can see L.H.S of both equations are equal but R.H.S is unequal so the system has no solution at all.

In short, Your Answer would be "No Solution"

Hope this helps!

(out loud) Find the percentages. 15m is what percent of 60m; 3m; 30m; 1.5 km?

N76 [4]

Answer: 15meter is 25% of 60m

15m is 500% of 3m

15m is 50% of 30m

15m is 1% of 1.5km.

Step-by-step explanation:

Given: 15m is what percentage of 60m; 3m; 30m; 1.5km

To find: Find the percentage.

Formula used: 1 kilometer=1000meter.

Explanation:

Let X percentage of 60m =15meter

So, X% of 60m =15m

$\frac{60X}{100}$ = 15m

Multiply both side by 100.

60X = 1500m

On dividing both side by 60

X = 25%

Let X percentage of 3m =15meter

So, X% of 3m =15m

$\frac{3X}{100}$ = 15m

Multiply both side by 100.

3X = 1500m

On dividing both side by 3

X = 500%

Let X percentage of 30m =15meter

So, X% of 30m =15m

$\frac{30X}{100}$ = 15m

Multiply both side by 100.

30X = 1500m

On dividing both side by 30

X = 50%

Let X percentage of 1.5km =15meter

Convert kilometer into meter by above formula (1.5km=1500meter)

So, X% of 1500m =15m

$\frac{1500X}{100}$ = 15m

Multiply both side by 100.

1500X = 1500m

On dividing both side by 1500

X = 1%

Therefore , 15meter is 25% of 60m

15m is 500% of 3m

15m is 50% of 30m

15m is 1% of 1.5km.
