Answer:
n, h = Naomi's and Hudson's work hours, respectively
n + h = 13
35n +20h = 395
Step-by-step explanation:
We are asked for the number of work hours of Naomi and Hudson. It is convenient to define the variables n and h to represent those hours, respectively. Then the system of equations is ...
n + h = 13 . . . . . . . . . . . . total work hours
35n +20h = 395 . . . . . . total shirts ironed
_____
The solution is Naomi worked 9 hours; Hudson worked 4 hours.
Answer:
70°
Step-by-step explanation:
All triangles' angles are added up to 180°
30 + 80 + x = 180
110 + x = 180
x = 180 - 110
x = 70
Answer: B. (2,1)
Step-by-step explanation:
its not c because if you look at R you see that it is going 4,3 not 3,4 because when you doing ratios on a number line it goes x-axis then y-axis next not y-axis then the x-axis.
It's not D because if you look at Q you see that it is going 3,5 not 5,3 because when you doing ratios on a number line it goes x-axis then y-axis next not y-axis then x-axis.
That's the same thing for A so your answer is b.
