Answer:
20x+4.99=y
Step-by-step explanation:
Each sweatshirt cost $20, but we don't know how many sweatshirts someone will buy so we use X, representing the amount of sweatshirts. There is a shipping charge of $4.99, so we have to add that to the cost of the sweatshirts. 20x+4.99. Y is the total cost.

A shelf is 36 inches long. How many DVD’s can I place on it if each one is 5/8 inches thick?
You can place approximately 57 DVDs on the shelf if each DVD is 5/8 inches thick. To determine the number of DVDs that can fit on a shelf, we need to divide the length of the shelf by the thickness of each DVD.
The shelf is 36 inches long, and each DVD is 5/8 inches thick.
Dividing the length of the shelf by the thickness of each DVD:
36 inches / (5/8) inches
To divide by a fraction, we multiply by its reciprocal:
36 inches * (8/5 inches)
Simplifying the multiplication:
288 inches / 5 inches
Now we can divide:
288 inches / 5 inches = 57.6
Therefore, you can place approximately 57 DVDs on the shelf if each DVD is 5/8 inches thick.

a store is having a sale on trail mix and jelly beans. For 5 pounds of trail mix and 6 pounds of jelly beans, the total cost is $23. For 3 pounds of trail kix and 2 pounds of jelly beans, the total cost is $11. Find the cost for each pound of traol mix and each pound of jelly beans
Answer:
j=$1.75/lb
t=$2.5/lb
Step-by-step explanation:
(1) 5t+6j=23
(2) 3t+2j=11, t=11/3 - 2j/3
sub t into (1):
5(11/3 - 2j/3) +6j = 23
55/3 -10j/3 +6j =23
8j/3=14/3
8j=14
j=7/4
sub j into t:
t=11/3 -2(7/4)/3
t=5/2
Make r the subject - picture underneath
Answer:
The answer is r = 6a / (5m² - 1).
Step-by-step explanation:
The steps are :
[tex]m = \sqrt{ \frac{6a + r}{5r} } [/tex]
[tex] {m}^{2} = \frac{6a + r}{5r} [/tex]
[tex]5r {m}^{2} = 6a + r[/tex]
[tex]5r {m}^{2} - r = 6a[/tex]
[tex]r(5 {m}^{2} - 1) = 6a[/tex]
[tex]r = \frac{6a}{5 {m}^{2} - 1 } [/tex]
Answer:
r = [tex]\frac{6a}{5m^2-1}[/tex]
Step-by-step explanation:
Given
m = [tex]\sqrt{\frac{6a+r}{5r} }[/tex] ( square both sides )
m² = [tex]\frac{6a+r}{5r}[/tex] ( multiply both sides by 5r )
5rm² = 6a + r ( subtract r from both sides )
5rm² - r = 6a ← factor out r from each term on the left side
r(5m² - 1) = 6a ← divide both sides by (5m² - 1)
r = [tex]\frac{6a}{5m^2-1}[/tex]

Harold cut 1812 inches off a rope that was 60 inches long. How is the length of the remaining rope in inches written in decimal form
Answer:
0.42
Step-by-step explanation:
The computation of the length of the remaining rope in inches is shown below:
Length Remaining = Length - the piece he cut off
Length Remaining = 60 - 18
60 - 18 = 42
To turn 42 into a decimal, you have to divide by 100 ↓
42 ÷ 100 = 0.42
The length of rope remaining is 0.42 inches long

A teacher gave a 3-question multiple choice quiz. Each question had 4 choices to select from. If the a student completely guessed on every problem, what is the probability that they will have 2 or less correct answers?
Answer:
0.9844
Step-by-step explanation:
This is a binomial probability problem.
Probability of getting a correct answer: p = 1/4
Probability of getting an incorrect answer: q = 3/4
Number of questions; n = 3
Thus;
probability of 2 or less correct answers is; P(x ≤ 2) = P(X = 2) + P(X = 1) + P(X = 0)
From binomial probability the formula is;
P(X = x) = C(n, x) × p^(x) × q^(n - x)
P(X = 2) = C(3, 2) × (¼)² × (¾)¹
P(X = 2) = 3 × 0.0625 × 0.75
P(X = 2) = 0.1406
P(X = 1) = C(3, 1) × (¼)¹ × (¾)²
P(X = 1) = 3 × 0.25 × 0.5625
P(X = 1) = 0.4219
P(X = 0) = C(3, 0) × (¼)^(0) × (¾)³
P(X = 0) = 0.4219
P(x ≤ 2) = 0.1406 + 0.4219 + 0.4219
P(x ≤ 2) = 0.9844
