Use substitution to solve the system of equations Y+x=3 Y=1.5x+1

Serjik [45]

The solution to given system of equation is (x, y) = (0.8, 2.2)

Solution:

Given system of equations are:

y + x = 3 --------- eqn 1

y = 1.5x + 1 ---------- eqn 2

We have to solve the above system of equations by substitution method

Substitute eqn 2 in eqn 1

1.5x + 1 + x = 3

Combine the like terms

2.5x + 1 = 3

Move the constants to Right hand side of equation

2.5x = 3 - 1

2.5x = 2

x = 0.8

Substitute x = 0.8 in eqn 2

y = 1.5(0.8) + 1

y = 1.2 + 1

y = 2.2

Thus the solution to given system of equation is (x, y) = (0.8, 2.2)

If you bike 8 miles south and then 6 miles east, what is the distance you are from your starting point? 10 miles 100 miles 14 mi

Andreyy89

Answer:

10 miles

Step-by-step explanation:

Given: Bike goes 8 miles south and then 6 miles east

To find: distance between the final point and the starting point

Solution:

Pythagoras Theorem

In a right angled triangle, square of hypotenuse is equal to the sum of squares of the two sides.

In ΔOAB,

$OB^2=OA^2+AB^2$

Put $OA=8\,,\,AB=6$

$OB^2=8^2+6^2=64+36=100$

Take square root on both sides.

$OB=\sqrt{100}=10\,\,miles$

So, distance between the final point and the starting point is 10 miles
