Answer:
d = 5
Step-by-step explanation:
The common difference d of an arithmetic sequence is
d = a₂ - a₁ = a₃ - a₂ = 
- 
Given
= 5n - 3
Generate the first 2 terms of the sequence by substituting n = 1, n = 2
a₁ = 5(1) - 3 = 5 - 3 = 2
a₂ = 5(2) - 3 = 10 - 3 = 7
d = 7 - 2 = 5
You are 16 or 16 and a half about to be 17
Answer:
x=-33/5 y=29/5
Step-by-step explanation:
Let's solve your system by substitution.
3x+y=−14;2x−y=−19
Solve
3x+y=−14 for y:
3x+y=−14
3x+y+−3x=−14+−3x(Add-3x to both sides)
y=−3x−14
Next is to substitute −3x−14 in for y 2x−y=−19:
2x−y=−19
2x−(−3x−14)=−19
5x+14=−19(Simplify both sides of the equation)
5x+14+−14=−19+−14(Add -14 to both sides)
5x=−33 Dived both sides by 5
5x/5=-33/3
x=−33/5 since you can't dived and a fraction is another form of division you keep it this way.
Step: Substitute -33/5 for x in y=−3x−14:
y=−3x−14
y=−3(-33/5)-14
y=29/5
(Simplify both sides of the equation)(since you can't dived and a fraction is another form of division you keep it this way.)
So
x=-33/5 and y=29/5
Pls mark brailest this took me a long time to write out lol. Hope this truly helps! Send a heart if so, so I can keep spreading the help!
Answer:
3 meters
Step-by-step explanation:
We are told that ...
the radius of circle P is half the radius of circle Q.
The same relation applies to any corresponding linear measures of these circles, so we can also say ...
the diameter of circle P is half the diameter of circle Q
the diameter of circle P is half of 6 meters, so is 3 meters
Answer:
0.954
Step-by-step explanation: 1 KG is 1,000 grams. So, if his geography book is 954 grams, it’s less than 1,000, so it would be a decimal, as 0.954.
