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
We can begin by rewriting the problem:
4(2x + 5) + 2x + 3 = -11
Let’s solve in steps.
1. Distribute
8x + 20 + 2x + 3 = -11
2. Combine like terms
10x + 23 = -11
3. Subtract 23 from both sides
10x + (23 - 23) = -11 - 23
10x = -34
4. Divide both sides by 10
10 / 10 = 1 (or x)
-34 / 10 = -3.4
Therefore, x = -3.4.
Write equation:-
The product of 5 and y added to 3
5 × y + 3
Answer:
27
Step-by-step explanation:
The expression is 3 + 4z
First, you must know what the value of the variable "z" is.
Because the problem already tells you that z = 6, all you have to do is substitute z with 4:
3 + 4z = 3 + 4(6)
Next, solve using the Order of Operations (P.E.M.D.A.S.).
According to the Order of Operations, multiplication (M) comes before Addition (A). That means you must multiply 4 by 6 first then add the product to 3:
3 + 4(6) = 3 + 24 = <u>27</u>
