A small number of cards has been lost from a complete pack. If I deal among four people, three cards remain. If I deal among three people, two remain and if I deal among five people, two cards remain. How many cards are there?
Answer:
1) The first filter to use is that if dealt between 5 people, there are 2 cards left over:
=> the number of cards must end in 2 or 7.
2) But if dealt between 4 people, 3 cards remain:
=> it is not possible for the number of cards to end in 2 as there cannot be a remainder of 3 with any even number, hence number must end in 7.
3) If the cards are dealt between 3 people to give n cards each, then 2 cards remain:
If 3n+remainder 2 ends in 7
=>3n ends in 5.
4) If 3n < 50 then the only possible numbers for 3n are 15 and 45.
We are told that a small number of cards are lost, so check 3n=45:
3n+ remainder 2= 47, and we are told that dealing between 4 leaves remainder 3:
47/4+= 11 remainder 3.
Hence the number of cards is 47.
the number of cards lost are 5 and the cards left are 47.
Step-by-step explanation:
We are given that certain number of cards are lost.
When divided among the four people, 3 cards are remaining. This implies that the number of cards lost may be 1,5 or 9 then only we will get the 3 cards left. Going by this approach, the number of cards available should be 52–1=51; 52–5=47; 52–9=43
Case 1: when one card is lost (available cards will be 51)
When 51 cards are divided among four people will give 3 remainders (48+3) which satisfies the given condition.
When 51 cards are divided among three people will give no remainder. But we expect the remainder to be 2. So, this case cannot be true.
Case 2: When 5 cards are lost (available cards will be 47)
When 47 cards are divided among four people will give 3 as remainder (44+3) which satisfies the given condition.
When 47 cards are divided among three people will give 2 as remainder (45+2) which satisfies the given condition.
When 47 cards are divided among five people will give 2 as remainder (45+2) which satisfies the given condition.

Kevin was accepted to college and is making plans for next year's budget. He anticipates getting a part-time job and making about $80 a week. In addition, his federal grants will be about $3,000 per semester. What is his income expected to be during the 36-week school year?
Answer:
Kevin's income is expected to be:
$8,880.
Step-by-step explanation:
Income from part-time job = $80 a week
For 36 weeks, he will earn $2,880 ($80 * 36)
Federal grants = $3,000 per semester
For semesters = $6,000 ($3,000 * 2)
Total income = income from part-time job plus the Federal grants
= $8,880 ($2,880 + $6,000)
The implication is that Kevin cannot spend above $8,880 towards his college education, unless he has another source of support during the year. Otherwise, he may resort to borrowing, via college loans.

10x+28−3x=7x+38 Does this equation have one solution, infinitely many solutions, or no solutions? Explain your answer.
Answer:
No solution
Step-by-step explanation:
First we have to solve the equation;
10x + 28 - 3x = 7x + 38
Collect like terms;
7x + 28 = 7x + 38
Subtract 7x from both sides;
28 ≠ 38
No solution, because the number does not equal each other.

Darcy and Jordan each had 1/2 of a single candy bar. Darcy ate 1/2 of her portion. How much of the candy bar did Darcy ingest?
Answer:
1/4
Step-by-step explanation:
The fraction 1/2 of 1/2 is 1/4 so Darcy ingests 1/4 part of a candy bar.
What is a fraction?The fraction is the division of the two numbers but the division is not wholly complete.
If we divide two numbers by each other then the upper word is called the numerator, and a lower word is called the denominator.
It represents the number of pieces removed from the whole. The denominator of a fraction is the numerical value that comes before the brings together various.
Amount of candy Darcy and Jordan have = 1/2
Amount of candy bar Darcy ate = 1/2 of 1/2
⇒ 1/2 (1/2) = 1/4
Hence "The fraction 1/2 of 1/2 is 1/4 so Darcy ingests 1/4 part of a candy bar".

The average of Landry’s test scores must be at least 92 for her to make an A in Algebra class. She got a 95 on her first test. What grade can Landry get on her second test to make an A in the class?
Average is determined by the sum of test scores divided by total number of tests. This can be represented in this equation:
95 + X / 2 = 92 ⇒ Multiply both sides by 2 to get of the divided by 2
95 + X /2 (2) = 92 (2)
95 + X = 184 ⇒ Subtract 95 from both sides to isolate x
95 -95 + X = 184 -95
X = 89
Therefore, they must get at least 89% to maintain an A.
A root beer factory produces 132,554 cases in 100 days. About how many cases does the factory produce in one day? Round your answer to the nearest tenth of a case. Show you thinking on a number line.
Answer:
1325.50 casesStep-by-step explanation:
In this problem, we want to calculate the number of cases made in one day,
let the number of cases that can be produced in a day be x
given that the factory produces 132,554 cases in 100 days
it can produce x cases in 1 day
cross multiply we have
100x=132,554
divide both sides by x we have
x=132,554/100
x=1325.54
Approximately 1325.50 cases

Identify the slope and y-intercept of the line. Then write the equation in slope form.
Answer:
The slope is -4, and the y-intercept is 1. The equation is y=-4x+1.
Step-by-step explanation:
To find slope use this equation:
(y2-y1)/(x2-x1)= slope (m)
And the y-intercept is b and you can find that just by looking at the graph.
y= -2/5X - 2
slope=
y-intercept=
9514 1404 393
Answer:
slope = -2/5y-intercept = -2Step-by-step explanation:
Compare your equation ...
y = (-2/5)x +(-2)
to the slope-intercept form ...
y = mx + b . . . . where m is the slope and b is the y-intercept.
Matching these patterns, you should be able to see that ...
m = -2/5 = slope
b = -2 = y-intercept
