Answer:
2
Step-by-step explanation:
We can set up equation for this one.
Let's say the number is X.
the sum of X and 14 can be expressed as : X+14
five times the sum of X and 14 can be expressed as 5(x+14)
and 5(X+14) = 80
The number is 2
A:because Pi is an irrational number and so is C because it does not repeat nor does it terminate but if you multiple 222 by 0.5 you got a whole number which you know is a Rational Number
Answer:
it would be a
Step-by-step explanation:
The probability of selecting a black sock is 1/4.
<h3>What is the required probability?</h3>
The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty. It is more likely that an event will occur if its probability is higher.
Number of white socks=20
Number of black socks=10
Number of red socks=6
Number of purple socks=4
Total number of socks=20+10+6+4
=40
Probability of getting a black sock=Number of black socks/Total number of socks
=10/40
=1/4

We know that
AB = 10x + 4
BC = 4x - 3
AC = 12x + 16
We need to find x, AB and BC.
The solution of the question is based on the assumption that the point A, B and C are col-linear, i.e. they lie on the same line, and B lies between A and C
⇒ AB + BC = AC
Substituting the values of AB, BC and AC in terms of x in the above equation, and solving the linear equation.
⇒ 10x+4 + 4x-3 = 12x+16
⇒ 14x+1 = 12x+16
⇒ 2x = 15
⇒ x = 7.5
Substituting the value of x in 10x+4 to determine the length of AB
AB = 10x+4
⇒ AB = (10×7.5)+4
⇒ AB = 75+4
⇒ AB = 79
Hence, AB is 79 units
Substituting the value of x in 4x-3 to determine the length of BC
BC = 4x-3
⇒ BC = (4×7.5)-3
⇒ BC = 30-3
⇒ BC = 27
Hence, BC is 27 units
