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:
1/16
Events A+B are written (P) yellow : 1/4 * (P) green : 1/4
Ao event = (P) 1/4 * 1/4 = 1/16
Step-by-step explanation:
Answer:
16 is the range
Step-by-step explanation:
First, arrange the numbers from least to greatest.
21, 25, 25, 26, 28, 37
Then, subtract 21 (smallest number) from the 37 (biggest number).
37 - 21 = 16
So, the range is 16
Have a wonderful day!
Answer:
12 mouthpieces, 24 reeds, 6 neck straps
Step-by-step explanation:
42 objects - 12 mouthpieces
= 30 objects left consisting of reeds and neckstraps
4 times as many reeds as neckstraps
think of it as 5 groups, 4 are reeds and 1 of nexkstraps
so divide 30 by 5 to get 6 per part.
4 of those parts = 24
1 of the parts = 6
so reeds = 24
neckstraps is 6
mouthpieces = 12
