Equivalent system, equivalent systema of equations
Answer:
2.01
Step-by-step explanation:
Assume x is cost of each bottle of juice.
2.75 + 8x = 18.83
8x = 18.83 - 2.75
8x= 16.08
x= 16.08 ÷ 8
x= 2.01

Answer:</h2>
- option (c) = -19 + x = -21
<h2>Step by step explanation:</h2>
<u>Question</u> : A number added to -19 is -21
<h3>
<u>Solution</u> ↓</h3>
First of all to make equation
Equation means LHS = RHS
For eg we take :-
50 - 20 = 10 + 20
30 = 30
Therefore, LHS = RHS
<h3>
According to the question :</h3>
- Which number would we add in -19 to get -21 and we get LHS = RHS
Make an equation
-19 + x = -21
x = -21 + 19
x = -2
Add -2 in the variable of x
Variable means any unknown value we used in maths. For eg :- x,y,z,a,b,c,p,q,r etc.
-19 + (-2) = -21
-19 - 2 = -21
-21 = -21
Therefore, LHS = RHS.
Answer:
stationary time is 2 hours 30 minutes
Traveling time is 3 hours 30 minutes
Step-by-step explanation:
There are two distinct line types on the graph
the horizontal ones and the ones going towards the upper part
The horizontal ones represent the stationary positions while the climbing one represent the traveling time
The horizontal ones are;
3 to 3:30
4-5
6:30 to 7:30
Time here is ;
30
minutes + 1 hour + 1 hour = 2 hours 30 minutes
The traveling time;
2 - 3
3:30 to 4
5 to 6:30
7:30 to 8
1 + 30 min + 1hr 30 + 30
= 3 hours 30 minutes
2y - 4x = 5.....add 4x to both sides
2y = 4x + 5....divide both sides by 2
y = 2x + 5/2 <==
