Rob has 40 coins, all dimes and quarters, worth $7.60. Write the system needed to determine the
number of dimes and quarters.
WILL GIVE BRAINLIEST
Answer:d + q = 40 -----> d = 40 - q
10d + 25q = 760
Substitute!
10(40 - q) + 25q = 760
400 - 10q + 25q = 760
15q = 360
q = 24
d = 40 - 24
d = 16

what's the answer to this quadratic equation
(x - 18)^2 = 1
Answer:
x=17 or x=19
Step-by-step explanation:
(x−18)^2=1
First, simplify both sides of the equation.
x*2−36x+324=1
Then subtract 1 from both sides.
x^2−36x+324−1=1−1
x^2−36x+323=0
Factor left side of equation.
(x−17)(x−19)=0
Then set factors equal to 0.
x−17=0 or x−19=0
x=17 or x=19
Answer:
Its either x=17 or x=19

Triangle CEN is congruent to Triangle CED. What property is shown by line segment CE being congruent to line segment CE?
Answer:
C. Reflexive property
Step-by-step explanation:
When a line segment is congruent or the same as itself, it is considered to have a property known as reflexive property.
This means line segment CE is a mirror image of itself. Therefore, line segment CE is congruent to line segment CE.
Line segment CE is what divides the figure given into two equal halves, making both parts congruent to each other.

solve the inequality 3x-3<9
Answer:
x < 4
General Formulas and Concepts:
Pre-Algebra
Equality PropertiesStep-by-step explanation:
Step 1: Define inequality
3x - 3 < 9
Step 2: Solve for x
Add 3 to both sides: 3x < 12Divide 3 on both sides: x < 4Here we see that any number x smaller than 4 would work as a solution.
Answer:
x < 4 is the answer.
Step-by-step explanation:
3x - 3 < 9 <----- This is the original question.
3x - 3 + 3 < 9 + 3 <----- Add 3 to both sides.
3x < 12 <-----Simplify
3x/3 < 12/3 <----- Divide both sides by 3.
x < 4 = x is less than 4

what is the slope of a line with endpoints (-11,5) and (5,-7)
Answer:
-6/8
Step-by-step explanation:
Slope=y1-y2/x1-x2
Where (X1,y1) is (-11,5) and (X2,y2) is(5,-7)
Slope=5+7/-11-5
=-12/16
= -6/8
So the slope is -6/8

YW is the perpendicular bisector of ZT.
If TW = 3, YW = 8, and XZ = 12. Find XY.
Answer:
XY = 17 UNIT
Step-by-step explanation:
Given:
TW = 3
YW = 8
XZ = 12
Find:
XY
Computation:
TW = ZW = 3
So,
XW = 12 + 3
XW = 15
So
XY = √XW²+YW²
XY = √15²+8²
XY = √289
XY = 17 UNIT
Applying the definition of perpendicular bisector and the Pythagorean Theorem, the value of XY is calculated as: 17 units.
Recall:
A perpendicular bisector of a line divides a line segment into two equal halves.Also, it forms two opposite right angles on the point of bisection.Considering the diagram attached below, we are given that:
[tex]TW = 3\\\\YW = 8\\\\XZ = 12[/tex]
We need to find the length of XY.Applying the Pythagorean theorem:
[tex]XY = \sqrt{XW^2 + YW^2}[/tex]
XW = XZ + WZ
XZ = 12 (given)
WZ = TW = 3 (congruent segments)
Thus:XW = 12 + 3
XW = 15
Plug in the values of XW and YW into [tex]XY = \sqrt{XW^2 + YW^2}[/tex]
Thus:[tex]XY = \sqrt{15^2 + 8^2}\\\\\mathbf{XY = 17}[/tex]

Your subtotal at the store was $58.89. You have a 30% off coupon. If the sales tax rate is 5.5%, what is the total price for your shopping trip?
Answer:
$43.48
Step-by-step explanation:
58.89x.30=17.68
58.89-17.68=41.21
41.21x.055=2.27
41.21+2.27= $43.48
Answer:
$43.49
Step-by-step explanation:
When you take of 30%, multiply by 0.7
When you add 5.5%, multiply by 1.055
Start with $58.89
Take off 30%: 0.7 * $58.89 = $41.22
Add 5.5%: 1.055 * $41.22 = $43.49

Find angle YWX using the perpendicular or angle bisector method.
Answer:
x = 5
Step-by-step explanation:
9x - 28 = 5x - 8 (because Y and X are equal, and XZ and YZ are equal)
add 8 to both sides
9x - 20 = 5x
subtract 9x from both sides
-20 = -4x
divide 4x from both sides
5 = x
x = 5

Cassie and her friend Molly played the balloon-pop game at the Belltown County Carnival. Cassie threw a total of 10 darts, 7 of which popped balloons. Molly threw a total of 5 darts, 4 of which popped balloons. Who had a greater ratio of darts that popped balloons to total darts?
Answer:
Molly had a greater ratio.
Step-by-step explanation:
If I were to multiply Molly's ratio by two it would give us 10:8 which is now comparable to 10:7 and 10:8 is greater than 10:7, therefore, Molly had the greater ratio. Hope this helps! Have a great day!
Question 3 40 pts
An object is attached to a spring that is stretched and released. The equation d = a (cos(bt)) models the distance, d, of the object in inches above or below the rest position as a function of time, t, in seconds. If a = 5 and b = 5 Approximately when will the object be 2 inches above the rest position? Round to the nearest hundredth, if necessary.
Answer:
The object will be 2 inches above the rest position when at approximately 0.23 seconds
Step-by-step explanation:
The given parameters are;
The equation that models the distance, d, of the object in inches above or below the rest position = a×(cos(b·t))
If a = 5 and b = 5, we have;
d = 5 × (cos(5 × t))
When the object is approximately 2 inches above the ground, we have;
d = 2 = 5 × (cos(5 × t))
cos(5 × t) = 2/5
5 × t = cos⁻¹(2/5) ≈ 1.16
t = (cos⁻¹(2/5))/5 ≈ 1.16/5
t ≈ 0.23 s
The object will be 2 inches above the rest position when t ≈ 0.23 s.
