The price of a pair of jeans was reduced from $20 to $15. By what
percentage was the price of the jeans reduced? *
Answers
Explanation:
1. Turn it into a fraction (15/20)
2. Divide the numerator (15) by the denominator (20). (15÷20=0.75)
3. Subtract 0.75 from 1 (1-0.75=0.25)
4. Turn 0.25 into a percentage by taking away the “0.” and adding a “%” at the end (25%)
Isaiah has $7.15 in Dimes and Nickels. He has a total of 91 coins. How many of each coin does he have? Group of answer choices dimes: 31 nickels 60 dimes: 60 nickels: 31 dimes: 52 nickels: 39 dimes: 39 nickels: 52
Answers
Answer:
Dimes = x = 52
Nickels = y = 39
Step-by-step explanation:
Let
Dimes = x
Nickels = y
x + y = 91 (1)
0.10x + 0.05y = 7.15 (2)
From (1)
x = 91 - y
Substitute x = 91 - y into (2)
0.10x + 0.05y = 7.15
0.10(91 - y) + 0.05y = 7.15
9.10 - 0.10y + 0.05y = 7.15
- 0.10y + 0.05y = 7.15 - 9.10
-0.05y = -1.95
y = -1.95 / 0.05
= 39
Substitute y = 39 into (1)
x + y = 91
x + 39 = 91
x = 91 - 39
x = 52
Dimes = x = 52
Nickels = y = 39

Step 2: Solve for b
Rewrite: -6 = 8bDivide 8 on both sides: -6/8 = bRewrite: b = -6/8[Fraction] Simplify: b = -3/4Step 3: Check
Plug in b into the original equation to verify it's a solution.
Substitute in b: -6 = (-3/4)8Multiply: -6 = -24/4Divide: -6 = -6Here we see that -6 does indeed equal -6.

Answers
Answer:
1.) The answer is b = 6
2.) The answer is t = 10
Step-by-step explanation:
For the first equation in order to fin out the answer we do.....
b + 8 = 14
b + 8 - 8 = 14 - 8
b = 6
For the second question we do....
25 - t = 15
25 - t + t = 15 + t
25 = 15 + t
25 - 15 = 15 + t -15
10 = t
A ladder 50 dm long when set against the wall of a house just reaches a window at a height of 48 dm. How far is the lower end of the ladder from the base of the wall?
Answers
Answer:
14dm
Step-by-step explanation:
To solve this question we can use the Pythogorean theorem
a^2 + b^2 = c^2
In this case, The ladder is the hypotenuse, the height is one of the leg of the right angle triangle
Let's keep the missing side as x
If we apply the theorem,
x^2 + 48^2 = 50^2
x^2 + 2304 = 2500
x^2 = 2500 - 2304
x^2 = 196
[tex]x = \sqrt{196} \\ x = 14[/tex]

Police chases a driver. The police is 1 mile behind the driver. The speed of the police is 90 mph, and the speed of the chased car is 85 mph. How long will it take for the police to catch up with the car?
Answers
Answer:
0.20 hour
Step-by-step explanation:
According to the problem, computation of the given data are as follows,
Speed of police = 90 mph
Speed of chased car = 85 mph
Distance to be chased = 1 mile
So, we can calculate the time to catch by using following formula:
Time required = Distance between two cars ÷ (Speed of Car A - Speed of Car B)
= 1 ÷ ( 90 - 85)
= 1 ÷ 5
= 0.20 hour

Answers
Answer:
[see below]
Step-by-step explanation:
Assuming that the equation is y = 10x + 1
(12, 4)
4 = 10(12) + 1
4 = 120 + 1
4 ≠ 121
(12, 4) is not a solution.
(1, 1.5)
1.5 = 10(1) + 1
1.5 = 10 + 1
1.5 ≠ 1
They are not solutions to the equation.

Step-by-step explanation:
Consider the provided equation.
[tex]2(6 - x) = x(x + 5)[/tex]
Remove the parenthesis and simplify.
[tex]12-2 x= x^2 + 5x[/tex]
[tex]x^2+7x-12=0[/tex]
Now use the quadratic formula [tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex].
Susbtitute a=1, b=7 and c=-12 in above formula.
[tex]x=\dfrac{-7\pm \sqrt{7^2-4(1)(-12)}}{2(1)}[/tex]
[tex]x=\dfrac{-7\pm \sqrt{49+48}}{2}[/tex]
[tex]x=\dfrac{-7\pm \sqrt{97}}{2}[/tex]

Cindy decided to shop online. She was buying books ($6 each) and candles ($4 each). She bought 15 items and spent $78. How many books did she buy?

Answer:
9 books
Step-by-step explanation:
78=b(6)+c(4)
78=9(6)+6(4)
78=54+24
78=78-True
As per linear equation, Cindy bought 9 books online.
What is a linear equation?"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation.
The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant. The standard form of a linear equation in two variables is of the form Ax + By = C. Here, x and y are variables, A and B are coefficients and C is a constant."
Given, Cindy was buying books ($6 each) and candles ($4 each).
She bought 15 items and spent $78.
Let, she bought 'x' books.
Therefore, she bought (15 - x) candles.
Now, the cost of the total 15 items is
= $[6x + 4(15 - x)]
= $[6x + 60 - 4x]
= $[2x + 60]
Therefore, 2x + 60 = 78
⇒ 2x = 78 - 60
⇒ 2x = 18
⇒ x = 9
Therefore, Cindy bought 9 books.
