Answer:
13 and 44
Step-by-step explanation:
let x and y be the 2 numbers with y < x , then
x - y = 31 ( add y to both sides )
x = y + 31 ( subtract 31 from both sides )
x - 31 = y → (1)
4y = x + 8 → (2)
substitute y = x - 31 into (2)
4(x - 31) = x + 8
4x - 124 = x + 8 ( subtract x from both sides )
3x - 124 = 8 ( add 124 to both sides )
3x = 132 ( divide both sides by 3 )
x = 44
substitute x = 44 into (1)
44 - 31 = y , then
y = 13
the 2 numbers are 13 and 44
Answer:
First blank on top of 4 is x.
Second blank under 5x is 8.
Step-by-step explanation:
We want to find the common denominator so we can combine the fractions on the left.
The common denominator we will go for is 8 since 4(2) is 8 and 8(1)=8.
So I'm going to multiply second fraction by 2/2 giving me:
Now that the denominators are the same we can write the sum as one fraction:
So 3x+2?=5x if ?=x since 3+2=5.
Now *=8 so both sides can have the same denominator.

Multiply second fraction by 2/2:
Answer: If Gregg colored none of the numbers blue, then obviously the chance the of his coloring being factorific would be zero.
If Gregg colored all of his cards blue, then again the chance would be 100%. This is because at least one of the cards is blue and all the divisors are blue.
On the other hand if only some of the cards are blue, then are numerous possibilities for the probability. You would have to create a chart and analyze each option to make sure the divisors were also blue.
