Answer:
∠5 = 35°
Step-by-step explanation:
∠5 = ∠2 because they are alternate interior congruent angles
∠5 = 35°
Answer:
The solution is obtained by adding the two equations.
The solution is: (x, y) = (
,
)
Step-by-step explanation:
We are given two equations with two variables. The strategy is to eliminate one variable and solve for both the variables.
The two equations are:


Adding both the equations, we get:



Substituting the value of 'x', we get the value of y.
We substitute in (2). [Can be substituted in any equation].
We get: y = 2x - 1



So, we get the corresponding values of x and y which is the solution of the two equations.
Answer:
20 Grams will be left after 6 minutes.
Step-by-step explanation:
The slope- intercept is y> (1-4x) / 5 and y< 2x + 6
<h3 /><h3>What is inequality?</h3>
A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.
Given:
4x – 5y < 1 and 1/2y – x < 3
Solving
4x – 5y < 1
-5y < 1- 4x
-y < (1-4x) / 5
y> (1-4x) / 5
Now, the second inequality,
1/2y – x < 3
1/2y< 3+x
y< 2x + 6

8 miles in 40 minutes = 12 miles per hour
5 miles in 30 minutes = 10 miles per hour
workings
60/40=1.5
1.5x8=12
60/30=2
2x5=10
method
you divide the 60 by however many minutes, then times that by the amount of miles
