Answer:
x = -7
Step-by-step explanation:
3(x – 4) = 5x + 2
Distribute
3x-12 = 5x+2
Subtract 3x from each side
3x-12-3x = 5x-3x+2
-12 = 2x+2
Subtract 2 from each side
-12-2 = 2x+2-2
-14 = 2x
Divide by 2
-14/2 = 2x/2
-7 =x

Answer:
2676 yards
Step-by-step explanation:
12*223 is 2676
if each costume requires 223 yards then all you do is multiply the numbers
To solve this problem we use the z test. The formula for z
score is:
z = (x – u) / s
where,
x = sample value = 13 and below
u = mean value = 27
s = standard deviation = 14
z = (13 – 27) / 14 = -1
using the z table to get the standard normal probabilities,
the p value at z = -1 is:
P = 0.1587
