<h3>Answer: Choice B)
</h3>
===========================
Explanation:
n = first number
n+2 = second number
Consecutive odd integers are odd numbers that follow one after another. Eg: {3, 5, 7, 9}
Note how I add 2 each time to get the next number. So that explains the "n+2"
Add up n and n+2, then set that sum equal to or larger than 84 like so
We could simplify or solve for n, but I'll stop here since this is what answer choice B is saying.
side note: "at least" means "that value or more". So if I said "at least 10", then I mean "10 or more".
Answer:
C
Step-by-step explanation:
Given the 2 equations
3x + 4y = 8 → (1)
y - 5x = 2 ← rewrite as
- 5x + y = 2 → (2)
Multiplying (2) by - 4 and adding to (1) will eliminate the y- term
20x - 4y = - 8 → (3)
Add (1) and (3) term by term to eliminate y
23x + 0 = 0
23x = 0 , then
x = 0
Substitute x = 0 into either of the 2 equations and solve for y
Substituting into (1)
3(0) + 4y = 8
4y = 8 ( divide both sides by 4 )
y = 2
solution is (0, 2 )
That is the lines intersect once at (0, 2 )
Answer: the total length of the string is 9 meters.
Step-by-step explanation:
The total number of strings that Emily measured is 3.
The length of the first piece of string measures 642 cm.
The length of the second piece of string measures 124 cm.
The length of the third piece of string measures 134 cm.
Therefore, the total length of the 3 pieces of string would be
642 + 124 + 134 = 900 cm.
100 cm = 1 m,
Converting 900 centimeters to meters, it becomes
900/1100 = 9 meters
Algebra I believe but I suck at math so don't take my word for it
