Answer:
A rational number is a number such as -3/7 that can be expressed as the quotient or fraction a/b of two integers, a numerator q and a non-zero denominator b. Every integer is a rational number: for example, 10 = 10/1.
Answer:
x=5, y=1
Step-by-step explanation:
Isolate x for 5x-3y=22
5x-3y=22
Add 3y to both sides
5x-3y+3y=22+3y
Simplify
5x=22+3y
Divide both sides by 5
5x/5=22/5+3y/5
Simplify
x=22+3y/5
Substitute x=22+3y/5
10*22+3y/5-4y=46
Simplify 10*22+3y/5-4y
10*22+3y/5=2(3y+22)
=2(3y+22)-4y
Expand 2(3y+22)
=6y+44-4y
Simplify 6y+44-4y
=2y+44
Isolate y for 2y+44=46
2y+44=46
Subtract 44 from both sides:
2y+44-44=46-44
Simplify
2y=2
Divide both sides by 2;
2y/2=2/2
Simplify;
y=1
For x=22+3*1/5 substitute y=1
y=22+3*1/5
22+3*1=25
=25/5
Divide the numbers;25/5=5
=5
x=5
The solutions to the system of equations are;
x=5, y=1
Answer:
-22,-4,4,37,69
Step-by-step explanation:
The greatest negative number (-22) is always smaller than the smaller negative number (-4).
4:1 means for every four soccer player there is 1 volleyball player
that means there are four times the number of soccer players than volleyball players
<span>The rate for such investment is 4% per
annum. This will be computed as follows: $12,000 (Future value of money) less $10,000
( Present value of money) is equal to $2,000 which will be then divided by 5
years and the it will give us the value of $400 per year. Then $400 will be
divided by the $10,000 ( Present value of money) which gives us 4%.</span>
