Answer:
470(32-n)
Step-by-step explanation:
We have such equation
1.25x=0.75x+50 /-0.75x (subtract 0.75 both sides)
1.25x-0.75x=0.75x-0.75x+50
0.5x=50 /*2 (multiply both sides times 2)
0.5x*2=50*2
x=100 - its the answer
Answer:
The diameter is 12
Step-by-step explanation:
37.68/3.14 = D π/ 3.14
D = 12 The diameter equals twelve.
Answer:
y = 2x + 12
Step-by-step explanation:
You can check this by plugging any of the values from the table into the equation. You can find the answer by finding the slope and then using that to find the y-intercept.
y2-y1/x2-x1
16-14/2-1 = 2/1 = 2. So our slope equals 2.
If we set x = 0 to find our y-intercept, and we know that we have a slope of 2 we can subtract 2 from 14 to get the y-intercept.
14-2 = 12. --> (0, 12) which is true because we know that the slope is 2.
Answer:
$454.5
Step-by-step explanation:
Current balance: -$25.50
Initial deposit: $120
Total deposit: $120 * 4 months = $480
