A handful of coins has the value of 1 dollar and 79 cents. There are three times as many dimes as quarters, and five more pennies than dimes. If there are only three types of coins, how many coins of each type are there?
Answer: There are 3 quarters , 9 dimes and 14 pennies.
Step-by-step explanation:
Let x= Number of quarters
Then, Number of dimes = 3x
Number of pennies = 3x+5
1 quarter = $ 0.25
1 dime = $0.10
1 penny = $ 0.01
So, Total amount = 0.25x+ 0.10(3x) + 0.01(3x+5)
= 0.25x+0.30x+ 0.03x+0.05
= 0.58x+0.05
Since Total amount = 1 dollar and 79 cents = $ 1.79 [1 cent = $ 0.01]
So,
[tex]0.58x+0.05=1.79\\\\\Rightarrow\ 0.58x= 1.74\\\\\Rightarrow x=\dfrac{1.74}{0.58}\\\\\Rightarrow x=3[/tex]
Thus, there are 3 quarters , 9 dimes , 14 pennies.
Answer:
Step-by-step explanation:
there are 3 quarters , 9 dimes , 14 pennies.

Someone help plz I need some help I don’t like slope!!!
Answer:
slope = 5
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 4, - 3) and (x₂, y₂ ) = (- 3, 2) ← 2 points on the line
m = [tex]\frac{2-(-3)}{-3-(-4)}[/tex] = [tex]\frac{2+3}{-3+4}[/tex] = [tex]\frac{5}{1}[/tex] = 5

B because that is how you do substitution and all of the other ones do not make sense
Find the inverse of y = - 1/2x - 5
9514 1404 393
Answer:
f^-1(x) = -2(x +5)
Step-by-step explanation:
Solve for x.
y +5 = -1/2x . . . . . add 5
-2(y +5) = x . . . . . multiply by -2
If you want this in "functional form", you can write it as ...
f^-1(x) = -2(x +5) . . . . . swap x and y, then use f^-1(x) for y
Find the intersection point for the following linear functions.

C.
(-5,-10)
D.
(-5,-7)
Answer:
(-5,-7)
Step-by-step explanation:
To find points of intersection, first set the two equations equal and then solve for x. Then substitute that x back into either equation for the complete point of intersection.
2x + 3 = -4x - 27
6x = -30
x = -5

What product is shown by the model. (15 Points)
Answer:
100
Step-by-step explanation:
So in this problem, we have 5 base 10 blocks and 50 ones.
To find out the product we have to count by tens:
10, 20, 30, 40, 50
So 5 base 10 blocks = 50
Now we add the base ten blocks and the ones together:
50 + 50 = 100
So the answer is 100
consider the steps for determining the quotient of 12/x-4 / 4/x-4
Answer:
Quotient = 3
Step-by-step explanation:
We need to solve the given expression :
[tex]\dfrac{\dfrac{12}{x-4}}{\dfrac{4}{x-4}}[/tex]
It can be done as follows :
As, [tex]\dfrac{\dfrac{a}{b}}{\dfrac{c}{d}}=\dfrac{a}{b}\times \dfrac{d}{c}[/tex]
So,
[tex]\dfrac{\dfrac{12}{x-4}}{\dfrac{4}{x-4}}=\dfrac{12}{x-4}\times \dfrac{x-4}{4}\\\\=\dfrac{12}{4}\\\\=3[/tex]
Hence, the required quotient is 3.

find values of x and y??
9514 1404 393
Answer:
x = 80y = 122Step-by-step explanation:
The angles marked with x-expressions are complementary, so ...
(3/4x -2) + (2/5x) = 90
x(3/4+2/5) = 92 . . . . . . . add 2
x(23/20) = 92 . . . . . . . . combine the fractions
x = 92(20/23) . . . . . . . . multiply by 20/23
x = 80
__
The angle marked y° is a vertical angle with the angle that is the sum of 90° and (2/5x)°. So, the value of y is ...
y = 90 + 2/5(x) = 90 +2/5(80) = 90 +32
y = 122
The cost for 25 square yards of carpet is $650 including delivery and installation. The cost for 40 square yards of installed carpet is $950. Write an equation in slope-intercept form (y = mx + b) for the cost of the installed carpet
Answer:
The equation is;
y = 20x + 150
Step-by-step explanation:
Firstly, let us identify the coordinates
(area, cost of area)
We start by getting the points;
(25,650) and (40,950)
The slope will be;
m = (y2-y2)/(x2-x1)
m = (950-650)/(40-25)
m = 300/15 = 20
So the partial equation is;
y = 20x + c
To get the value of c which is the y-intercept, we make use of any of the two points
650 = 20(25) + c
650 = 500 + c
c = 650-500
c = 150
5) Rory sold T-shirts at a festival for $15 each. He paid $100 in materials and fees.
Rory's profit after the festival was $350. He wants to know how many shirts he sold,
6) Which quantity is unknown?
6) the number of shirts sold
• Let s equal the number of shirts sold. Which equation represents the situation?
15(8 – 100) = 350
158 = 350
8 - 100 = 350
158 - 100 = 350
Answer:
We need to find the number of shirts he sold using: 15s - 100 = 350
s = 30
So, Rory sold 30 shirts :)
The required expression that defines the scenario is 15s - 100 = 350 and the number of t-shirts sold is 30. Option D is correct.
Given that,
Rory sold T-shirts at a festival for $15 each. He paid $100 in materials and fees. Rory's profit after the festival was $350. He wants to know how many shirts he sold.
According to the assertions, it deals with a number of operations in mathematics. Addition, subtraction, multiplication, and division are the four main arithmetic operators.
Here,
Let the number of the t-shirts be s,
According to the question,
Total cost of s t-shirts = 15s
He spends $100 on materials,
Profit = 15s - 100
15s - 100 = 350
Thus, the required expression that defines the scenario is 15s - 100 = 350 and the number of t-shirts sold is 30. Option D is correct.

Answer:
down 2, right 1
Step-by-step explanation:
Here, we want to know what -2 means for the slope
The following conventions are necessary to be known;
down is negative
left is negative
up is positive
right is positive
Thus;
Since the slope is actually vertical change/ horizontal;
The 2 value must be in respect to the y-axis
Hence;
up 2 right 1 is positive
down 2 left 1 is positive since both are negatives
The correct answer is thus;
down 2, right 1
