Answer:
B) 40 necklaces with 25 left over
Step-by-step explanation:
To do this, we must allow this hidden number to be x.
2x + 4 = 8
Now we will solve by first subtracting 4 from each side:
2x = 4
Now we will divide each side by 2 to isolate the variable:
x = 2
Therefore, the mystery number is 2.
Answer:
x=4.375
Step-by-step explanation:
-3(2x-7)+5=2x-9
-6x+21+5=2x-9
-6x+26=2x-9
-6x-2x+26=2x-2x-9
-8x+26=-9
-8x+26-26=-9-26
-8x=-35
-8x/-8=-35/-8
x=4.375
Answer:
y = 5-x
Step-by-step explanation:
Given the data:
x -2 1 3 6
y 7 4 2 -1
Linear equation :
y = 5 - x
Y = mx + b is the equation
m = slope, or 3
b = y-intercept, or 1
y = 3x + 1
is your equation
