Answer:
There are 7 chairs in each row.
Step-by-step explanation:
Hue is arranging some number of chairs. If she arranges them in 6 rows of equal lengths then there will be 3 chairs leftover, or she arranges them in 8 rows of that same length then she requires 11 more chairs.
Let us assume that there are P numbers of chairs and there are x chairs in each row.
Therefore, we can write that
6x + 3 = P ....... (1) and
8x = P + 11
⇒ 8x - 11 = P ........ (2)
Now, from equations (1) and (2) we get,
6x + 3 = 8x - 11
⇒ 2x = 14
⇒ x = 7
Therefore, there are 7 chairs in each row. (Answer)
2t+3n=9 2(2)+3n=9
+5t-3n=5 (the 3n cancel out) 4+3n=9
7t=14 3n=5
t=2 n=5/3 or 1.67
Answer: Y=5x-3
Slope is 5/1
Y-int is (0,-3)
p = m v
Divide each side by 'm' : <em>p/m = v</em>
Answer: (-2,1)
Step-by-step explanation:
y=x+3
y=2x+5 substitute the y value in the first equation into the second equation
x+3 = 2x+5 now solve for x
-3 -3
x = 2x +2 subtract 2x from both sides
-2x -2x
-1x = 2 Divide both sides by -1
x= -2
The value of x is -2 to plot it into one of the equations to solve for y.
y= -2 + 3
y = 1
(-2,1)
