14 mph
Step-by-step explanation:
13.636364
is what you get by doing
100/15 then you get 6.6666......7
after that you multiply that by 3600 because thats how many seconds in that hour.
Then you get 24000 and transfer it to miles and get 13.636364 and you round it and get 14mph
Y = 5/4x - 10
5x - 4y = 40
Let's rewrite the second equation to y = mx + b form
5x - 4y = 40
subtract 5x from both sides
-4y = -5x + 40
divide both sides by - 4
y = 5/4x - 10
<span>What can you conclude about the equations?
Well, it's the same thing just written in slope-intercept form and standard form.
Hope this helps</span>
Answer:
6.
Step-by-step explanation:
We can start by defining a couple things.
x = amount of nickels
y = amount of dimes
Since he has the same amount of each, we can say this.
x = y
And because we know it totals 0.90, we can say this.
0.05x + 0.10y = 0.90
then, we substitute and get this.
0.05x + 0.10x = 0.90
Simplify.
0.15x = 0.90
Divide both sides by 0.15.
x = 6
So we have 6 nickels, and they both are the same, so we have 6 dimes.
