Answer:
In 23 hours they make 80.5 bagels. The unit rate is 3.5 bagels per hour
Step-by-step explanation:
Divide 10 hours by 10 hours to get 1 hour.
Divide 350 bagels by 10 to get the unit rate (which is 3.5)
Multiply the unit rate by 23, and you get 80.5 hours.
1. To solve this exercise, you must make a system of equations.
2. You have that f<span>our times a number minus twice another number is -8:
</span>
4x-2y=-8
3. And t<span>he sum of the two number is 19:
</span>
x+y=19
4. As you can see, you have two equations:
4x-2y=-8 (i)
x+y=19 (ii)
5. Let's clear the "x" from the equation (ii):
x=19-y
6. Now, you need to susbtitute x=19-y into the equation (i):
4x-2y=-8
4(19-y)-2y=-8
76-4y-2y=-8
76-6y=-8
-6y=-8-76
-6y=-84
y=-84/-6
y=14
7. You must susbstitute y=14 into the equation (ii) and clear "x":
x+y=19
x+14=19
x=19-14
x=5
The answer is: 5 and 14
Hi there
The answer is
b.) y=8,000(1.14)^x
Good luck!
