Answer:

Lrge number is 8, Small number is 5

Step-by-step explanation:

Lets use two variables, g and t

$G-T=3\\G+T=13\\$

Lets find G and subsitute the equation

$G-T=3\\G=3+T$

SOlve

$(3+T)+T=13\\3+2T=13\\2T=10\\T=5\\G=8$

CHECK:

$8-5=3\\3=3\\8+5=13\\13=13$

Which values from the set {−6,−4,−3,−1,0,2} satisfy this inequality?

Vladimir [108]

-12x+3 greater than or equal to 5
-12x greater than or equal to to 2
To turn the negative sign of -12x into positive, we multiply both sides by minus, which shifts the inequality sign.
So, 12x less than or equal to 2
x is less than or equal to 1/6
Therefore, 0, -1, -3, -4 and -6 satisfy this inequality.

Answer:

There was a 1.93% probability of having multiples (twins or more) in 1980.

Step-by-step explanation:

There were 3,612,258 births in the US in 1980.

Of those,

68339 + 1337 = 69676 were multiplies.

What was the probability of having multiples (twins or more) in 1980?

$P = \frac{69676}{3612258} = 0.0193$

There was a 1.93% probability of having multiples (twins or more) in 1980.
