Answer:
see below
Step-by-step explanation:
Let N = how much Nellie spends
Let D = how much Debbie spends
Part A
Nellie spends $122 more than Debbie.
N= D +122
Their total expenses amount to $840.
N+D =840
The two equations are
N= D +122
N+D =840
Part B
We can substitute the first equation which is solved for N into the second equation. Every place we see an N in the second equation, we replace it with D+122
Part C
N= D +122
N+D =840
(D+122) +D = 840
Combine like terms
2D +122 = 840
Subtract 122 from each side
2D+122-122=840-122
2D =718
Divide by 2
2D/2= 718/2
D =359
Debbie spends 359

ANSWER
a. 6
EXPLANATION
On a dot plot , we use dots to represent frequencies.
The frequency 6, is represented by 6 dots.
The frequency 7, is represented by 7 dots.
The frequency 9, is represented by 9 dots.
The frequency 8, is represented by 8 dots.
The smallest number of dots is represented by 6.
You're given d = 10
10 = -1.5t<span>2 = 110

Answer:
29.187
Step-by-step explanation:
Cos38°= base/hypotenuse
Cos38°= 23/w
w= 23/Cos38°
w= 23/0.788
w= 29.187
Hope it helps :-)
