8 * 2 * 10 = 160 * 10 = 1600
Answer:
Blank 1: 40
Blank 2: 10
Step-by-step explanation:
You can start by representing the speed of the water as x and the speed of the dolphin as y, and writing an equation.
y+x=50
y-x=30
Adding these two equations together, you get:
2y=80
y=40 for the speed of the dolphin in still water. Now, you an use one of the previous equations to find the speed of the current.
40-x=30
x=10
Hope this helps!
3 x 30
It cost 30 pesos per dozen and they are buying 3 dozen
3 x 30 = 90
Answer:
An inequality often covers an infinite area. Depending on the problem, any area either below or above the function is included in the set of solutions.
For example, see the attached photo.
y < x is graphed here.
When you substitute x = 0 into the function, y will equal 0 and this point is a solution to the problem. However, if any point under this line, such as (1, 0), (-9, 0), or even (1000000000, 0), was chosen, these are still solutions to the inequality, but not the problem.
