Answer:
The speed of the cars is 
Step-by-step explanation:
First we must first have the clear concept that 
or 
Our question is the speed of the cars then the variable to clear will be s.
Let's raise the equation for each car taking into account that we have the following data:
Car 1: 
, 
and 
Car 1: 
, 
and
The two cars travel the same distance so we will raise the distance formula for each car and then match them.
<em>Car 1</em>
<em>Car 2</em>
The speed of the cars is 32 km/hr
Answer:
Redskins cost $0.25 and golden roughs cost $0.35.
Step-by-step explanation:
Let r be the cost of a redskin and g the cost of golden roughs. So we have the system of equations:
r + 4g = 1.65
2r + 3g = 1.55
Multiply the first equation by -2:
-2r - 8g = -3.30
Adding this to the second equation:
-5g = -1.75
g = 0.35.
Now substitute this into the first equation:
r + 4*0.35 = 1.65
r = 1.65 - 1.40
r = 0.25.
Answer:
A
Step-by-step explanation:
Using the recursive formula with a₁ = 5 , then
a₂ = 2a₁ - 7 = 2(5) - 7 = 10 - 7 = 3
a₃ = 2a₂ - 7 = 2(3) - 7 = 6 - 7 = - 1
a₄ = 2a₃ - 7 = 2(- 1) - 7 = - 2 - 7 = - 9 → A
