Multiply both sides by 4
subtract 24r from both sides
simplify r - 24r to -23r
divide both sides by -23
two negatives make a positive
simplify 14/5/23 to 14/5 x 23
simplify 5 x 23 to 115
switch sides
Answer: r = 14/115.
D, because there are several students that are in your school. There would be many different answers.
Answer: C is correct, No solution
Step-by-step explanation:
Let’s simplify the second equation,
8x-4y=-20
We can divide the whole equation by 4...
8x/4-4y/4=-20/4
Which becomes....
2x-y=-5
Now let’s move things around to see if it’s the same equation as the one on top...
-y=-2x-5
y=2x+5
Now we need to solve the systems...
y=2x-5
y=2x+5
Since their slopes are both 2 and their y-intercepts are not identical, the answer is no solution. The two lines will continue on without ever crossing because they have the same slope.
Step-by-step explanation:
apply Pythagorean theorem. if a^2 + b^2 = c^2 then
b = √(15^2 - 9^2) = 12.
12 is answer
Answer:
They should in crease budget.
Step-by-step explanation:
divide each number by 2 to see how often they go equally/use the data table you have available of the two climbers.
