The answer to the question
Answer:
B) 275n + 1000 = 2700
Step-by-step explanation:
n is just a placer holder for how many days the Carter family can vacate.
That being said, the question says that they will spend 275 per day, which is per n. You want to multiply 275 by n.
Then the question says it plans to spend $1000 on meals (that's a lot). Instead of substracting, you are going to add for this equation. You want the equation to match; you want both sides to equal 2700 so you can determine how many days you can spend there.
Answer:
x= - 3.5
y= - 6.5
Step-by-step explanation:
-3x+y = 4 equation 1
-9x + 5y = -1 equation 2
and
equation 1 can be written as
y = 4+ 3x
so put this in equation 2
-9x + 5 ( 4+ 3x) = -1
-9x +20 +15x = -1
6x = -21
X= -21 ÷ 6
X = - 3.5
so put this value of x in equation 1 to find value of y
-3 ( -3.5) + y = 4
10.5 + y = 4
y = 4 - 10.5
Y = - 6.5
Answer:
B
Step-by-step explanation:
its a number line, start at 3, move back -4, end at -1. the arrow above the line shows that its moving backwards/subtraction
