Step-by-step explanation:
15t + 30 = 20t | -15t
30 = 5t
t = 30/5 = 6
20 + 5t = -6t + 86 | + 6t
20 + 11t = 86 | -20
11t = 66
t = 6
18t + 20 = 24t + 50 | -18t
20 = 6t + 50 | -50
-30 = 6t
t = -30/6 = -5
18t - 2 = 10t + 54 | -10t
8t - 2 = 54 | +2
8t = 56
t = 56/8 = 7
7t - 5 = 15t + 91 | -7t
-5 = 8t + 91 | -91
-96 = 8t
t = -96/8 = -12
Answer:
the answer would be 2187
Step-by-step explanation:
3 to the 6th would be 729 and times it by 3 you get 2187
Answer:
b=(13/4, -27/4, -4)
Step-by-step explanation:
A.x=b
x=(a, b, c)
a - b + 2c = 2
3a + b + 0 = 3
0 + 0 + c = -4
solving this system
c=-4
a-b=10, 3a+b=3
a=10+b, 3(10+b)+b=3
b=-27/4
a=10-27/4
a=13/4
Answer:
2x-64<108
One solution was found :
x < 86
Rearrange:
Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :
2*x-64-(108)<0
Step by step solution :
Step 1 :
Pulling out like terms :
1.1 Pull out like factors :
2x - 172 = 2 • (x - 86)
Equation at the end of step 1 :
Step 2 :
2.1 Divide both sides by 2
Solve Basic Inequality :
2.2 Add 86 to both sides
x < 86
Nicole rented the bike for 26.6 minutes.
43=15+57(x)
now because 57 is the hourly rate it needs to be divided by the number of minutes in one hour (60).
57/60=0.95cents
now put that aside for later use, the next step in the equation is to subtract the one time fee of $15 from the total spent.
$28 is what is left, now it's time to take that 0.95 and put it to use!
28*0.95=26.6
to double check that the math is correct take the 15+28 and make sure it adds up to 43
