Answer:
C) 2/5×1/4
Step-by-step explanation:
Dividing by a number is the same by multiplying by the reciprocal of the number.
For Example:
1/2 divided by 3 would be the same as 1/2 x 1/3
So for this problem we are given that 2/5 is divided by 4 which would be the same as 2/5 multiplied by the reciprocal of 4 which is 1/4 and thus the answer is option C which is 2/5×1/4
System of Linear Equations entered :
[1] 5x - 6y = 7
[2] 6x - 7y = 8
Graphic Representation of the Equations :
-6y + 5x = 7 -7y + 6x = 8
Solve equation [2] for the variable x
[2] 6x = 7y + 8
[2] x = 7y/6 + 4/3
// Plug this in for variable x in equation [1]
[1] 5•(7y/6+4/3) - 6y = 7
[1] - y/6 = 1/3
[1] - y = 2
// Solve equation [1] for the variable y
[1] y = - 2
// By now we know this much :
x = 7y/6+4/3
y = -2
// Use the y value to solve for x
x = (7/6)(-2)+4/3 = -1
Answer:
$600
Step-by-step explanation:
subtract 45 from 75, you get 30. multiply 30 by 20, and there is your answer.
Answer:
35 + .2m
Step-by-step explanation:
The monthly fee of $35 is a base pay, and you don't change anything with it.
The "m" stands for minute, and since it costs $.20 for each minute, multiply the two together to get that part of the equation.
Answer:
Step-by-step explanation:
<u>Volume:</u>
<u>Given r = 5 cm and V = 110 cm³, find h:</u>
- 1100 = π(5²)h
- 1100/25 = πh
- 44 = πh
<u>Curved surface area:</u>
- S = 2πrh = 2*5*πh = 10*44 = 440 cm²
Correct choice is C
