Answer: $15
The original price of the mirror is unknown, so let's call it x.
The discount on the original price is a 20% discount, so it is 20% of x, or 0.2x.
We are told the discount is $3, so 0.2x = 3. Now we solve the equation for x.
0.2x = 3
Divide both sides by 0.2.
x = 3/0.2
x = 15
The regular price is $15.

PLS HELP... What value of x satisfies the equation below? 5(x - 3)= 10x + 5
Answer:
x = - 4
Step-by-step explanation:
First do distributive property
5x-15=10x+5
then add 15
5x=10x+20
-10x
-5x=20
divide 5
x=-4
Answer:
x = -4
Step-by-step explanation:
5(x−3) = 10x+5
5x−15 = 10x+5 (Simply both sides of the equation)
−5x−15 = 5 (Subtract 10x from both sides)
−5x = 20 (Add 15 to both sides)
−5x /−5 = 20 /−5 (Divide both sides by -5.)
x = -4

Ella has 0.5 lbs of sugar. How much water should she add to make the following concentrations? Tell Ella how much syrup she will have in each case.
75% syrup?
Answer:
Step-by-step explanation:
Let amount of water in lbs is x
so, mass of solution = mass of water + mass of sugar
= (x + 0.5) lbs
concentration of syrup = mass of sugar/mass of solution × 100
75 = 0.5/(x + 0.5) × 100
or, 75/100 = 0.5/(x + 0.5)
or, 3/4 = 0.5/(x + 0.5)
or, 3x + 3 × 0.5 = 4 × 0.5
or, 3x + 1.5 = 2
or, 3x = 0.5
or, x = 0.167 lbs
hence, amount of water is 0.167 lbs
Answer:
0.167lbs

On a fish tank 1/5 of the fish are guppies and 1/12of the fish are gold fish.Which equation most closely estimates the fraction of the fish that are guppies or goldfish in the fish tank
Answer: 17/60
Step-by-step explanation:
Suppose that whe have N fishes.
We know that 1/5 of these N fishes are guppies.
We also know that 1/12 of these N fishes are goldfish.
Now, what is the fraction of guppies and goldfish together?
We only need to add the fractions:
1/5 + 1/12
This may be hard because the denominators are different, then the first step will be to write both fractions with the same denominator.
We know that:
5*12 = 60
Then we can write:
1/5 = (12/12)*(1/5) = 12/(5*12) = 12/60
and
1/12 = (5/5)*(1/12) = 5/(5*12) = 5/60
Then our previous sum:
1/5 + 1/12
can be written as:
12/60 + 5/60
and this is easy to solve:
12/60 + 5/60 = (12 + 5)/60 = 17/60
This is the fraction of the fish that are guppies or goldfish.

A group of friends wants to go to the amusement park. They have $94.25 to spend on parking and admission. Parking is $14.75, and tickets cost $13.25 per person, including tax. Write and solve an equation which can be used to determine pp, the number of people who can go to the amusement park.
Answer: 6
Step-by-step explanation:
From the question, we are informed that a group of friends wants to go to the amusement park and that they have $94.25 to spend on parking and admission.
We are further told that Parking is $14.75, and tickets cost $13.25 per person, including tax. The equation that can be used to solve the number of people who can go to the amusement park would be:
= 14.75 + 13.25p
Since they've $94.25 to spend, the number of people that can go to the amusement park will be:
14.75 + 13.25p = 94.25
13.25p = 94.25 - 14.75
13.25p = 79.50
p = 79.50 / 13.25
p = 6
6 people can go to the amusement park
An expression that is equal to 28.3

The Hiking Club plans to go camping in a State park where the probability of rain on any given day is 2/3. What is the probability that it will rain on exactly four of the four days they are there? Round your answer to the nearest thousandth.
Answer:
19.75%
Step-by-step explanation:
Since we are trying to find the probability for a sequence of events then we need to multiply the probability of each event happening separately from each other. Since the probability of it raining on a single day is 2/3 we need to multiply this value with itself 4 times (one for each day).
2/3 * 2/3 * 2/3 * 2/3 = 16/81 or 0.1975 or 19.75%
Therefore the probability would be 16/81 or 0.1975 or 19.75%
On a loan of $32,000 at 7% interest for 6 months, how much do you wind up paying to pay off the loan?
$45,440
$33,120
$32,240
$38,720
Answer:
45440
Step-by-step explanation:
32,000*6*.07=13440
13440+32,000+45,440
The amount we have to pay at the end of the 6month period will be $33,120. The rate of interest on the loan is given as per annum and therefore; the interest is to be calculated for 6 months.
What is simple interest?Simple interest is a method of calculating the interest charge. Simple interest can be calculated as the product of principal amount, rate and time period.
Simple Interest = (Principal × Rate × Time) / 100
Calculation of settlement amount of loan:
Given:
Principle= $32,000
Rate= 7%
Tenure= 6 months
Interest is calculated from the following formula;
Interest= Principle x rate x tenure
Therefore the interest for the loan will be;
Interest = $32,000 x 7 x 6 months
= 32,000 x 7/100 x 6/12
= $1,120
The final payment for the loan will be the combination of principal and interest.
Therefore final payment = $32,000 +$1,120
= $33,120

what is the slope of this graph
Answer:
The slope of the line = m = 2
Step-by-step explanation:
Given
The points
(0, 0)(1, 2)To determine:
The slope of this graph
Determining the slope between (0, 0) and (1, 2)
(x₁, y₁) = (0, 0)(x₂, y₂) = (1, 2)Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [2 - 0] / [1 - 0]
= 2 / 1
Thus, the slope of the line = m = 2

Answer:
Step-by-step explanation:
3t−18=4(−3− 43 t)
can someone help me pls
Hey there! :)
3t - 18 = 4(-3 - 43t)
Let's start on the right side of the equal sign by multiplying "4" with everything inside of the parenthesis. Keep in mind that a negative times a negative is a positive & a negative times a positive is a negative.
4 × -3 = -124 × -43t = -172tLet's put this all together:
3t - 18 = -12 - 172t
Now, we need to isolate "t." We can do this by adding 18 to both sides along with adding "172t" to both sides.
3t - 18 + 18 + 172t = -12 - 172t + 172t + 18
Simplify.
3t + 172t = -12 + 18
Simplify - add like terms!
3t + 172t = 175t-12 + 18 = 6Let's put this all together:
175t = 6
Divide both sides by 175.
175t ÷ 175 = 6 ÷ 175
Simplify.
t = 6/175Hope this helped! :)

175t-18=-12
Step 4
175t-18=-12 Add 18 to sides
175t=6

175t=6 Divide sides by 175

Why is subtracting an expression similar to distributing a –1? Use the drop-down menus to explain your answer.
You each term inside the parentheses by –1 in order to subtract each term, since subtraction Is the additive inverse.
Answer:
When subtracting expressions, we are applying the distributive property, where a multiple of an expression in brackets is applied to to each term.
e.g.
a(x + y) = ax + ay
In the case of subtracting an expression, we're doing the same thing, but in the example above, "a" would be equal to -1.
(a + b) - (c + d) ≡ (a + b) + -1(c + d)
And so the negative one is distributed across the terms within the brackets.
