Answer:
Identity property of multiplication
Step-by-step explanation:
From step 5:
Here, to solve for x so that the variable x stands alone, Alberto uses the identity property of multiplication, which justifies what he has in step 6.
Step 6:
According to the identity property of multiplication, any value you multiply by 1 gives you that same value.
Therefore, 1x = 1 × x = x.
The variable x multiplied by 1 will give you x.
This is one of the photos I used to answer, I’m going to send the second one
There are a few ways you can go about solving this question. One way is to use the given information to find how many tons of flour can be processed in one hour. If 27 tons can be processed in 3 hours, we can do 27 divided by 3 to find that 9 tons of flour can be processed per hour. Then, if we want to see how many tons of flour can be processed in 8 hours, we can multiply 9 tons by 8 hours to get a total of 72 tons of flour.
I hope this helps.
Answer:
c. (2, -18)
Step-by-step explanation:
y = -5x - 8
y = 3x - 24
3x - 24 = -5x - 8
8x = 16
x = 2
y = 3x - 24
y = 3(2) - 24
y = 6 - 24
y = -18
Answer: c. (2, -18)
