P = 2 ( 1 + w ) for 1
1 = 2 ( 1 + w )
Simplify
1 = 2w + 2
Subtract 2 from both sides
2w = -1
Divide by 2
2w = -1
/2 /2
w = -1/2
Answer:
a) -4/3
b) 8
c) -2/3
d) 2
Step-by-step explanation:
In all four cases replace the value of "x" in the function's expression, and evaluate to find the numerical answer:
a)
b)
c)
d)
Decimal means x/100
we know that 20 times 5=100 and and equivilent of a fraction is x/x or 1 so
3/20=3/20 times 5/5 so 15/100 or
15%
Answer:30
Step-by-step explanation:because it is very diffeculy sorry
Answer
let the first number be x
second number be y
5*(x)+y=-21---------->equation 1
2*(x)+y=-9------------->equation2
<h2>
eq1 * 2:</h2>
2(5x+y)=2*-21
10x+2y=-42
<h2>
eq2 * 5:</h2>
10x+5y=-45
10x+2y=-42
-(10x+5y=-45)
-----------------
0 - 3y=3
y=3/-3
<h2>
y=-1</h2><h3>
sub y=-1 in eq1;</h3><h3>
5x+y=-21</h3><h3>
5x+ -1=-21</h3><h3>
5x-1=-21</h3><h3>
5x=-21+1</h3><h3>
5x=20</h3><h3>
x=20/5</h3><h2>
x=4</h2><h2>
y=-1</h2>
