Step-by-step explanation:

Given

2a + b = 6......equation 1

a - 6 = b

a = b + 6........equation 2

Putting equation 2 in equation 1

2 ( b + 6 ) + b = 6

2b + 12 + b = 6

3b = 6 - 12

3b = - 6

b = - 6 / 3

Therefore b = - 2

Now

a = - 2 + 6 = 4

hope it will help :)

Answer:

a = 4

b = -2

Step-by-step explanation:

2a + b = 6

a - 6 = b

a - b = 6

Elimination

2a + b = 6

a - b = 6

________+

3a = 12

a = 12/3

a = 4

a - b = 6

4 - b = 6

-b = 6 - 4

-b = 2

b = -2

James is 1.63 meters tall. Write James’s height in word form. Explain how you Found your answer.
kobusy [5.1K]

Answer:

James is 1 meter and 63 centimeters tall

Step-by-step explanation:

James is 1 meter and 63 centimeters tall. The first step will be to subtract 1 from his height;

1.63 - 1 = 0.63 meters

The 1 subtracted is equivalent to 1 meter. The next step is to convert the remaining height in meters to centimeters by multiplying by 100;

0.63 * 100 = 63 centimeters

We can thus say, James is 1 meter and 63 centimeters tall or equivalently 163 centimeters tall
