Answer:
14n - 29
Step-by-step explanation:
First you'd distribute in the parentheses by -5. -5 × -2.4n and -5 × 4 which you would get 12 and -20.
Then, bring everything down and combine like terms. 2n + 12n = 14n || -9 - 20 or -9 - (-20) = -29. 14n - 29 is the lowest you can simplify because you can subtract a variable and a constant together.
Answer:
Simultaneous equations
Step-by-step explanation:
4a + 7m = 17.75
2a + 5m = 10.75
Double the 2nd equation and then subtract the two equations to cancel the 4a out
Work with the 'm' terms and find the value of m
After finding the value of 'm', substitute it into one of the original equations (the ones given in the question) and solve to find the value of 'a'

The answer is 15 i believe
Answer:
The answer is option D
Step-by-step explanation:
Circumference of a circle is πd
where d is the diameter
From the question
d = 6½ feet = 13/2 feet
Circumference is
π × 13/2
= 22/7 × 13/2
= 143/7
![= 20 \frac{3}{7}](https://tex.z-dn.net/?f=%20%3D%2020%20%20%5Cfrac%7B3%7D%7B7%7D%20)
