There are several information's already given in the question. Based on those information's the answer can be easily arrived at. Let us first write down the details given.
Cost of a box of 10 wings = $7.00
Cost of a tray of nachos = $4.00
Amount that Freddy can spend is less that $40.
Then the equation will be
7x + 4y < 40
I hope the procedure is clear enough for you to understand.
Let c represent the speed of the current.
time = distance/speed
Upriver, the current is subtracted from the canoe speed; downriver, it adds.
6 = 32/(12 -c) +32/(12 +c)
6(12² -c²) = 32(12 +c) +32(12 -c) . . . . . multiply by (12 +c)(12 -c)
0 = 6c² -96 . . . . . . . . . . . . . . . . . . . . . . subtract the left side
96/6 = c² . . . . . . . . . . . . . . . . . . . . . . . . add 96, divide by 6
4 = c . . . . . . . . . . . . . . . . . . . . . . . . . . . . take the square root
The rate of the current is 4 mph.
Answer:
1/3
Step-by-step explanation:
The equation given to you is in y=mx+b form.
m is the slope which in this case would be 2/9.
b is the y-intercept which in this case would be 1/3
Answer:
30 different ways
Step-by-step explanation:
Hi
for the first topping she can choose 1 of 6 items
so she has 6 choices
and then the second topping she has 5 choices as each topping can only be chosen once
so it comes 6 * 5 = 30
