Answer:
Inequality form : x>-2
Step-by-step explanation: Divide each term by -5 and simplify.
Hope this helps.
Let
x--------> Peter's drive speed on the highway in mph
y--------> Peter's drive speed on country roads in mph
we know that
x=25+y-------> equation 1
70/y=120/x------> 70*x=120*y-----> x=120*y/70------> equation 2
remember that
time=distance/speed
equate equation 1 and equation 2
25+y=120*y/70-----> multiply by 70 both sides
70*[25+y]=120*y-----> 1,750+70*y=120*y-----> 50*y=1,750------> y=35 mph
x=25+35------> x=60 mph
the answer is
Peter's drive speed on the highway is 60 mph
Peter's drive speed on country roads is 35 mph
If the stripes are not lined up equally then they are not equivalent.
hope this helps :D
Answer:
82/125
Step-by-step explanation:
656/1000 = 328/500 = 164 / 250 = 82/125
Answer:
B
Step-by-step explanation:
a difference of cubes factors in general as
a³ - b³ = (a - b)(a² + ab + b²)
given
p³ - 343q³
= p³ - (7q)³ ← a difference of cubes , then
= (p - 7q)(p² + 7pq + 49q²) ← in factored form
