Answer:
C. 5 miles
Step-by-step explanation:
Since we need to find how many miles they ran together, let us convert feet to miles. Sarah's length is already in miles so we'll leave it that way.
Jaime ran 15840 feet. We are given how many feet are there in one mile (5280), so we need to find how many miles are there in 15840 feet.
x = 15840 / 5280 = 3 miles.
So, Jaime ran 3 miles and Sarah ran 2 miles.
That means that together they ran 3 + 2 = 5 miles.
Answer:
Step-by-step explanation:
Factor each half of the expression separately:
Since both 4k² and 7 are being multiplied by (7k-6), we can combine them to get:
That is true because you are still dividing x by three either way
Answer: 240 people get the news from social media
Step-by-step explanation:
The ratio of the number of people who get their news from social media to the number of people who their news elsewhere is 3:7
Total ratio is the sum of the proportion of those that get their news from social media and those that got their news elsewhere.
It becomes 3+7 = 10
Total number of people in the town is 800
To determine the number of people that got their news from social media, we will divide the proportion of those that get their news from social media by the total ratio and multiply by the total number of people in the town. It becomes
3/10 × 800 = 240
There's nothing to multiply. However, you can factor it to get (x + 4)(x - 4).
