Answer:
4 * 2y + 4 * 1
4(2y + 1)
Distributive property
Step-by-step explanation:
8y + 4
We can factor out a 4 out of both as both are divisible by 4
8y / 4 = 2y
4 / 4 = 1
So 8y + 4 is the same as saying 4 * 2y + 4 * 1
This can be written as 4(2y + 1) which is written using the distributive property
Answer:
5 miles
Step-by-step explanation:
There are 60 minutes in 1 hour, so to find how many miles he can walk, we simply multiply:
Other people (regular people) pay houses off over the years or write a check
We must solve for x. Let's simplify this equation by dividing both sides by 6:
|2x-14|=7, which is the same as 2|x-7|=7.
First, assume that x-7 is already positive, so that we don't need the absolute value operator. Then x-7=7/2. Adding 7 to both sides results in x = 21/2.
Next, find the other solution:
Assume that x-7 is negative. Then |x-7|=-(x-7). Then -(x-7) = 7,
and -x + 7 = 7. Thus, x = 0.
The solution set is {0, 21/2}.
