$2.39 is 100%
$x is 7%
2.39 x 7 = 16,73
16,73/100 = 0,17
the total cost is $2,56
Answer:
Step-by-step explanation:
6)Let the number be x
Product of a number and -4 = x * -4 = -4x
Product of a number and -4 increase by 3 : -4x + 3
-4x +3 = 9
Subtract 3 from both sides
-4x + 3 - 3 = 9 - 3
-4x = 6
Divide both sides by (-4)
-4x/-4 = 6/-4
x = -3/2
x = -1 1/2
7)Let the number be x

Add 9 to both sides

Multiply both sides with 6

x = 120
Answer:
y=2x-1
Step-by-step explanation:
If you are supposed to write the equation in slope-intercept format, (y=mx+b), then y=2x-1 would be the answer. 2 is the slope(m), and -1 is the y-intercept(b). I hope thus helped :).
I think Its C because in the frequency table or table given if the heads are counted there are 6 of them and over all 10 which will make 6/10
