Answer:
x = 40
Step-by-step explanation:
50 + 150 + 2x + x + x
200 + 4x
360 - 200 = 160
160 / 4 = 40
x = 40
50 + 80 + 40 + 150 + 40
Answer:
Ravi’s average speed is 7 miles per hour
Step-by-step explanation:
In this question, we are tasked with calculating what Ravi’s average speed was.
We must know that the term average speed is mathematically equal to Total distance/ Total time
We already have the time of 3 hours, what is needed is the distance.
From the question, we can see that they met at the point where Pilar had travelled 55 miles. What this means is that Ravi would have traveled (55-34) miles to this point since they are coming in opposite direction. This means that Ravi had traveled 21 miles
Thus his average speed is 21 miles/ 3 hours = 7 miles per hour
Answer:
The equation in standard form is

−
y
=
7
.
Explanation:
The standard form for a linear equation is
A

B
y
=C
, where
A
,
B
,
and
C
are numbers, and
x
and
y
are variables.
y
=

x
−
7
Subtract

x
from both sides of the equation.

A = P(1 +rt) where A is the total amount(principal and interest), r is the rate, and t is the time invested.
A = 5200[1 + .0736(4.5)]
A = 6922.24
note we had to change the rate to a decimal by dividing by 100
Also 54 months is equal to 4.5 years...you enter time in years.
