Let n = number
"3 times the sum of a number and 7" translates to 3(n + 7)
"2 less than five times the number" translates to 5n - 2
The word "is" becomes the equals sign.
3(n + 7) = 5n - 2
I think you already asked this one.
Answer: the slope is 2
Explanation:
The graph goes up 2 and over 1. When finding slope the formula is rise/run
Answer:
2^5
Step-by-step explanation:
2^4 × 2^6 ÷ 2^5
= 2^10 ÷ 2^5
=2^5
The two friends will be 150 miles apart, when the sum of the distances covered by the them is 150 miles.
distance = speed x time.
Let the time covered when they are 150 miles apart be x, then:
40x + 35x = 150
75x = 150
x = 150/75 = 2.
Therefore, the two friends will be 150 miles apart in 2 hours.
