Let’s let the number of nickels be x. Then the number of dime must be 33-x.then 5x+10(33-x)=240 5x+330-10x=240 330 5x=240 x5=90x=18
Answer:
x = - 6
Step-by-step explanation:
Given
x + 5 = 1 ( subtract 5 from both sides )
x = - 4
Multiply both sides by 3 to clear the fraction
2x = - 12 ( divide both sides by 2 )
x = - 6
Using it's concept, it is found that there is a 0.8 = 80% probability that the learner is a senior or a male.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, there is a total of 6 + 4 + 5 = 15 students. Of those, there are 6 seniors, and 6 male non-seniors, hence there are 12 desired outcomes, and the probability is given by:
p = 12/15 = 0.8 = 80%.

The symbol is ">" (not "≥") so the line is dashed, not solid.
A solid line is used to indicate the boundary line is part of the solution, as it is in the "or equal to" case.

Step-by-step explanation:
Sunny earns $22.75 per week delivering. delivery boy for 3 weeks.
That means $22.75 x 3 not $22.75 + 3
He can correct his mistake by doing this:
<em>Step 1: [($22.75 * 3) + $32.75 - $14.25] * 1/ 5
</em>
<em>
