Answer:
80 grapes
Step-by-step explanation:
6 pounds x 40 = 240
240 / 3 = 80
or you can do:
6 / 3 = 2
2 x 40 = 80
M = 44
b = 48
Equation: y = 44x + 48
Proportional
Positive slope
Answer:
30.5 hours
Step-by-step explanation:
If he were to average 8 hours PER week for 4 weeks, his total sum would have been:
8 * 4 = 32 hours
But he fell short of it. By how much?
By
hours!
So, he practiced 1 1/2 hours LESS THAN 32 hours, so his practice time is:

So, <u>he practiced 30.5 hours in the 4 weeks</u>
Hello!
Let's write some important information contained in the exercise:
• hotdogs: $2.59 (,x,)
,
• hamburgers: $5.29 (,y,)
He needs 11 packages. Let's write it:
• x + y = 11
He spent a total of $39.29. We can write it as:
• 2.59x + 5.29y = 39.29
Now, let's solve these two equations as a linear system:

First, let's isolate x in equation A:

Now, we will replace where's x by 11-y in equation B:

As I called the hamburgers as 'y', we know that he bought 4 packages of hamburgers.
