she has $7.85 in quarters and dimes
quarters = 25c
dimes = 10c
she has 12 more
so, we know she has AT LEAST 12 quarters
25 x 12 = 300 = $3.00
but we also know its not possible for her to have more dimes quarters
( im not rlly sure what to do, bc you havent given me multiple choices, but i hope this helps )
What is the equation of a line with a slope of 1/2
that passes through the point, (-2,5) ?
The equation of a line is written as y = mx + b where m is the slope.
Replace M with the slope to get:
y = 1/2x + b
Now replace x and y with the given point to solve for b:
5 = 1/2(-2) + b
SImplify:
5 = -1 + b
Add 1 to both sides:
b = 6
The equation of the line is y = 1/2x + 6
Which inequality describes all the solutions to 5(3-x)<-2x+6
Answer:
x < 3
Step-by-step explanation:
5(3 - x) < -2x + 6
Distribute;
15 - 5x < -2x + 6
Add 2x to both sides;
15 - 3x < 6
Subtract 15 from both sides;
-3x < -9
Divide both sides by -3
x < 3

per pot
Answer:
13.75
Step-by-step explanation:
You would do 18.75 divided by 5 to get the cost of each pot.
18.75 / 5 = 13.75

Mathematics question
8y=48? as a one step equation-integer.
Answer:
the answer is 6y
Step-by-step explanation:
you just divide by 8 and get 6 and add the variable for 6y
The solution of the equation 8y = 48 by combining like terms with the use of operations addition, division, etc is y = 6.
Used the concept of an equation that states that,
An equation is a group of numerical variables and functions that have been combined using operations like addition, subtraction, multiplication, and division.
Given that the expression is,
8y = 48
Now simplify the expression by combining like terms with the use of operations addition, division, etc.
The expression is,
8y = 48
Divide both sides by 8,
y = 48/8
y = 6
Therefore, the solution is y = 6.

Step-by-step explanation:
The monthly cost (in dollars) of water use is a linear function of the amount of water used (in hundreds of cubic feet, HCF). The cost for using 14 HCF of water is $33.79, and the cost for using 27 HCF is $55.24. What is the cost for using 18 HCF of water?
Answer:
The cost of using 18 HCF = $40.39
Step-by-step explanation:
A linear function is one that has a constant rate of change for all the values within the distribution. For a linear function, there is a constant, and that constant is known as the slope or gradient of the linear function.
Let us first calculate this constant (slope).
Let:
X₁ = 14 HCF, Y₁ = $33.79, X₂ = 27 HCF, Y₂ = $55.24, m = slope
[tex]m = \frac{Y_2-Y_1}{X_2 - X_1} \\m = \frac{55.24 - 33.79}{27-14} \\m = \frac{21.45}{13} \\m = 1.65[/tex]
at any two points on the linear function, the rate of change of the cost to HCF = 1.65
Now, Let X₃ = 18 HCF, Y₃ = cost for using 18 HCF
[tex]m = \frac{Y_3 - Y_1}{X_3-X_1} \\where\ m= 1.65\\1.65 = \frac{Y_3-33.79}{18-14}\\1.65 = \frac{Y_3 - 33.79}{4} \\6.6 = Y_3 - 33.79\\Y_3 =6.6+33.79\\Y_3 = 40.39[/tex]
Therefore, the cost of using 18 HCF = $40.39
N:B X₂ and Y₂ can also be used with X₃ and Y₃ to find Y₃. You can try it out, you should get the same result

Find 4 solutions (in radians) of sine = 0.18.
9514 1404 393
Answer:
0.180986, 2.96061, 6.46417, 9.24379
Step-by-step explanation:
The first solution to ...
sin(x) = 0.18
is found by using the arcsine function:
x = arcsin(0.18) ≈ 0.180986
Additional positive values can be found by subtracting this angle from π, and by adding multiples of 2π to either of the values obtained so far.
π - 0.180986 ≈ 2.96061
Adding 2π to these gives two more values:
0.180986 +2π ≈ 6.46417
2.96061 +2π ≈ 9.24379

Kite
Trapezoid
Isosceles Trapezoid
Answer:
Rhombus
Step-by-step explanation:
Another quadrilateral that you might see is called a rhombus. All four sides of a rhombus are congruent. Its properties include that each pair of opposite sides is parallel, also making it a parallelogram. In summary, all squares are rectangles, but not all rectangles are squares.
