Step-by-step explanation:
Answer:
Step-by-step explanation:
y = k*x This is the formula for a direct variation.
- y = 20
- x = 4 Substitute these values into the direct variation
20 = 4 * k Divide by 4
20/4 = 4k/4
k = 5
Answer: the constant of variation is 5
Answer: C. 105 km
Step-by-step explanation:
By finding out that 1 cm is equal to 7 km, and that the two cities are 15 cm apart you can find it out by doing 7 x 15.
Enjoy. :)
Answer:
The solution is obtained by dividing the number of flowers by the number of vases.
Step-by-step explanation:
The story problem is very straightforward. Normally, you need to read the problem and understand it.
Let's look at the question again.
Although we do not have all the quantities, we can still show how to solve the problem.
Let x be the total number of flowers.
There are 4 vases.
Therefore, the number of flowers in each vase will be:
x/4
Flow the same rule for similar problems.
Answer:
one
Step-by-step explanation:
When a system of equations is graphed, the solution is the coordinate that is plotted at the intersection of the two lines.
If the two lines cross once, there is only one solution.
If the two lines are on top of each other then there are infinitely many solutions.
If the two lines are parallel ( and never touch ) then there are no solutions
By looking at the graph we notice the two lines intersect once. So we can conclude that there is only one solution.
