Answer: I would say B would be the answer Because....
Step-by-step explanation:
if about 20 to 23 cars pass through every 26 minutes, and haw many cars pass by in 156 minutes...
26 x 6 = 156
6 x 20 = 120
6 x 21 = 126
6 x 22 = 132
6x 23 = 138
all thoes numbers are around B.

The value of the factorial is 5!4!/7!2! = 2/7
<h3>What is factorial?</h3>
The product of all positive integers less than or equal to a given positive integer and denoted by that integer and an exclamation point.
Given:
5!4!/7!2!
= 5!* 4*3*2!/7*6*5!*2!
=4*3/7*6
=12/42
=4/14

Step-by-step explanation:
If x is the volume of the first tank, and y is the volume of the second tank, then:
x + y = 55
x = 2y + 4
Solve the system of equations using either substitution or elimination. Using substitution:
2y + 4 + y = 55
3y + 4 = 55
3y = 51
y = 17
Solve for x using either equation.
x + 17 = 55
x = 38
The first tank holds 38 gallons, and the second tank holds 17 gallons.
