Solve the following system:

{y = 5 x + 2 | (equation 1)
{3 x = 10 - y | (equation 2)
Express the system in standard form:

{-(5 x) + y = 2 | (equation 1)
{3 x + y = 10 | (equation 2)

Add 3/5 × (equation 1) to equation 2:
{-(5 x) + y = 2 | (equation 1)
{0 x+(8 y)/5 = 56/5 | (equation 2)

Multiply equation 2 by 5/8:
{-(5 x) + y = 2 | (equation 1)
{0 x+y = 7 | (equation 2)


Subtract equation 2 from equation 1:
{-(5 x)+0 y = -5 | (equation 1)
{0 x+y = 7 | (equation 2)

Divide equation 1 by -5:
{x+0 y = 1 | (equation 1)
{0 x+y = 7 | (equation 2)

Collect results:
Answer:  {x = 1                         {y = 7

There are 25 prime numbers between 1 and 100. There are 46 prime numbers between 1 and 200. Which situation is more likely? Expl
Alekssandra [29.7K]

Answer:

One.

Step-by-step explanation:

There is a 25% chance of situation one happening.

\frac{prime}{total} =\frac{25}{100} = 0.25=25%

There is a 23% chance of situation two happening.

\frac{prime}{total} =\frac{46}{200}=0.23=23%

Since the chance is two percent bigger from situation one, situation one should be the one that is more likely to happen.

y=180-142

y=38 degree

x=y(being alternate angles)

x=38 degree
