Answer:
Step-by-step explanation:
You aren't able to figure out an exact number of either footballs or basketballs because you don't have enough information for that, but you do have enough to get an expression for one in terms of the other, which I imagine is the point here. We know that for every 1 basketball sold, we sold 2.5 footballs, so the algebraic expression for that is
1 bball = 2.5 fballs
This gives us the number of bballs in terms of fballs but we want the number of fballs in terms of bballs, so solve that expression for fballs:
1 fball = 1/2.5 bballs
or, in words, for every single football sold, 2/5 of a basketball was sold. Sounds silly, but I think your teacher is trying to get you to figure out how to express one thing in terms of another so you can use the expressions in solving story problems.

Answer:
The probability that a randomly selected woman has red/green color blindness is 0.9914
Step-by-step explanation:
Given that the proportion of women having red/green color blindness is 0.86%
Represent that with p
Convert proportion from percentage to decimal;
In probability; opposite probabilities add up to 1;
Let the probability that a woman selected have red/green color blindness be represented with q;
Subtract p from both sides
Substitute 0.0086 for p
<em>Hence, the probability that a randomly selected woman has red/green color blindness is 0.9914</em>
Answer:
20
Step-by-step explanation:
cause 2/3 * 6 is 4 then 4*5 is 20
Answer:
one solution
Step-by-step explanation:
7x - 3 = 5x + 5 ( subtract 5x from both sides )
2x - 3 = 5 ( add 3 to both sides )
2x = 8 ( divide both sides by 2 )
x = 4
3 2/3 or three and two thirds
