The cow produces 5 liters a day.
You want to find how much it will produce a day if the cow produces 200% more milk. So, you use the equation p*(1+x/100)
<span>5×(1+200/100)=15</span>
postive or greater6 7 8 9 10
negative or less 4 3 2 1 0
Answer:
11
Step-by-step explanation:
Paralell has same slope
y=mx+b
m=slope
y=1/2x+b
find b
(x,y)
(4,0)
x=4
y=0
0=1/2(4)+b
0=2+b
minus 2 both sides
-2=b
the equaiton is
y=1/2x-2
or
x-2y=4
<span>From the problem, you can get this equation:
Jane is 2 years older than Sally
J=z+2
David is 4 times older than Jane.
D=4J
</span>Write two equivalent expressions that represent David’s age in terms of Sally’s age, z, and explain how the two expressions relate to one another.<span>Sally is z years old.
From the 2 equation above, you can get:
</span>D=4J
D=4(z+2)
D=4z+8
D-8=4z
(D-8)/4=z
The two equivalent expression would be D=4z+8 and (D-8)/4=z
The expression that more usefull would be D=4z+8 if you want to determine David age.
