Answer:
4 1/2 hours
Step-by-step explanation:
To find how long, multiply the length of time in hours by the number of cakes. 1 cake takes 3/4 of a an hour so 6 cakes will take
3/4 * 6 = 18/4 = 4 2/4
4 2/4 simplifies to 4 1/2 hours.
Answer: You bought 7 books and you also bought 4 magazines
Explanation:
x = # of books purchased
y = # of magazines purchased
System of equations:
8x + 5y = 76
x + y = 11
Let’s use elimination in this case, but substitution can also work.
8x + 5y = 76
Multiply the (x + y = 11) by -8
We get:
8x + 5y = 76
-8x - 8y = -88
The xs cancel.
Add like terms.
-3y = -12
Divide by -3 on both sides
y = 4
Now plug in 4 into the (x + y = 11) equation to get x.
x + (4) = 11
Subtract 4 on both sides
x = 7
Answer:
the factor is x=1/2 or x=1
