<span>The sum of two numbers is 48.
a + b = 48
;
If one third of one number is 5 greater than one sixth of another number,
a = b + 5
multiply both sides by 6, cancel the fractions
2a = b + 30
2a - b = 30
</span><span>use elimination to solve this
a + b = 48
2a - b =30
-------------Addition eliminates b, find a
3a = 78
a =
a = 26
then
26 + b = 48
b = 48 - 26
b = 22</span>
Answer:
Step-by-step explanation:
5x -x + 3x =30, first you combine like terms 5x + 3x-x=30
8x-x =30
8-1=7
7x=30
The conversion of feet to meters is obtained by multiplying 1 foot = 0.3048 meters.
<h3>What are the basic measurements for length?</h3>
Foot, inches, centimeters, and meters are the basic measuring units for length.
<h3>What are the basic conversions?</h3>
The basic conversions are:
1 kilometer = 1000 meters
1 meter = 100 cm
1 cm = 10 mm
1 mm = 0.03937 inch
1 inch = 0.0833 feet.
<h3>How to convert feet to meters?</h3>
According to the international system of units,
1 foot = 12 inches ...(1)
But we know,
1 inch = 25.4 mm, 1 mm = 0.1 cm, and 1 cm = 0.01 m
By substituting all of these in equation (1), we get
1 foot = 12(25.4 mm)
= 304.8 mm
= 304.8 (0.1 cm)
= 30.48 cm
= 30.48(0.01 m)
= 0.3048 meters
Therefore, 1 foot = 0.3048 meters.
