A washer and a dryer cost $950 combined. The washer costs $ 100 more than the dryer. What is the cost of the dryer?
Answer:
$850
Step-by-step explanation:
washer + dryer = $950
if washer cost=>$100
Therefore; the value of the dryer should be x
$100+x=$950
x=$850
The dryer cost is =>$850
Answer:
The dryer is $425.
Step-by-step explanation:
Washer = 100 + Dryer
Set up an equation:
Variable x = dryer
x + x + 100 = 950
x + x = 850
2x = 850
x = 425
Dryer = 425
Bonus answer:
Washer = 100 + x
Washer = 100 + 425
Washer = 525
Check your work:
Washer + Dryer = 950
525 + 425 = 950
950 = 950
Correct!

[tex]x > 4[/tex]
Step-by-step explanation:
X is greater than 4
Find the value of x and y
Answer:
x = 10 and y = 15
Step-by-step explanation:
The arrows on lines AB and CD indicate that they are parallel. This means that we have to look for Z-angles (I don't know if they are called the same where you're from but I hope you recognise the term). This means that ∠ABC = ∠BCD
5x - 20° = x + 20°
4x = 40°
x = 10°, which gives us the first answer.
The angle formed by points ACE (a straight line) is 180 degrees. Lets refer to this as angle ACE. We also know this angle consists of angle ACB, BCD and DCE. This gives us the following equation:
angle ACE = angle ACB + x + 20° + y + 20° = 180°
angle ACB + x + y + 40° = 180°
angle ACB = -x - y + 140°
Inserting the x we found earlier this gives
∠ACB = - y + 130°
Now we can find a second equation to describe ACB by looking at the triangle it is inside. The angles in a triangle always add up to 180°, giving the following expression:
4y - 25° + 5x - 20° + ∠ACB = 180°
Substituting x again gives
4y - 25° + 50° - 20° + ACB = 180°
ACB = 180 - 4y - 5° = 175° -4y
Combining the two expressions for ACB gives the final equation to solve:
175° - 4y = -y + 130°
-3y = -45
y = 15

anyone know the answer??
Answer:
X (2, 1)
Y (2, 3)
W (5, 5)
Step-by-step explanation:
The current points are:
X (-2, -1)
Y (-2, -3)
W (-5, -5)
Now, after rotating 180 degrees around the origin, here is what points Y, Y, and W would look like:
X (2, 1)
Y (2, 3)
W (5, 5)
Plot these new points on the graph, and you'll have a new figure which will be rotated to 180 degrees.
I have also provided you with a graph, showing both, the original and the rotated version, below.

Find the measure of the missing angle of each
Answer:
? = 120, ? = 145, respectively
Step-by-step explanation:
? + 60 = 180
? (+ 60 - 60) = 180 - 60
? = 120
35 + ? = 180
(35 - 35) + ? = 180 - 35
? = 145

A cube made of an unknown material has a height of 9 cm. The mass of this cube is 3,645 grams. Calculate the density of this cube given this information. Hint: a cube has equal sides
Answer:
Step-by-step explanation:
Volume of the cube = s^3
s = 9cm
V = 9 * 9 * 9
V = 729 cm^3
d = mass / volume
d = 3645 / 729
d = 5 grams / cm^3

Answer:
Page 3 - the y-intercept would remain at 5 and the slope would be 3 times the upward slope.
Page 5 - the y-intercept would remain at -2 and the slope would be 1/4 instead of 5
Step-by-step explanation:
In point slope form the slope and y-intercept can be read directly from the equation.
y = mx + b where m is the slope and b is the y-intercept.

PLEASE
Answer:
r =√[3V/(π h)]
Step-by-step explanation:
V = ⅓ × π r²h
=> multiplied by 3
3V = π r² h
=> find r²
r² = 3V/(π h)
=> find r
r =√[3V/(π h)]
Answer:
[tex]r=\sqrt{\dfrac{3V}{\pi h}}[/tex]
Step-by-step explanation:
Given equation:
[tex]V=\dfrac{1}{3} \times \pi r^2 h[/tex]
To isolate [tex]r[/tex], multiply both sides by 3:
[tex]\implies V \times 3=\dfrac{1}{3} \times \pi r^2 h \times 3[/tex]
[tex]\implies 3V= \pi r^2 h[/tex]
Divide both sides by [tex]\pi h[/tex]:
[tex]\implies \dfrac{3V}{\pi h}= \dfrac{\pi r^2 h}{\pi h}[/tex]
[tex]\implies \dfrac{3V}{\pi h}=r^2[/tex]
Square root both sides:
[tex]\implies \sqrt{r^2}=\sqrt{\dfrac{3V}{\pi h}}[/tex]
As the radius is positive only:
[tex]\textsf{Apply radical rule} \quad \sqrt{a^2}=a, \quad a \geq 0[/tex]
[tex]\implies r=\sqrt{\dfrac{3V}{\pi h}}[/tex]
-16 + the quotient of a
number and -4 is -3
Answer:
76
Step-by-step explanation:
let the number be x
Then 16 + x/-4 = -3, so
x/-4 = -16-3 = -19 (add -16 on both sides)
x = -4*-19 = 76 (multiply by -4 on both sides)
Can anyone help? It’s not -312,44,nor 92
Answer:
60
Step-by-step explanation:
4a + 2b² -2(a-3b)
a = 2 and b = 4
4(2) + 2(4)² - 2(2-3(4))
8 + 32 -2(2-12)
40 - 2(-10)
40 +20
60
Therefore 60 is correct.
A, B & C form a triangle where Z BAC = 90°.
AB = 7.3 mm and CA = 4.6 mm.
Find the length of BC, giving your answer rounded to 1 DP.
Answer:
BC ≈ 8.6
Step-by-step explanation:
Using Pythagoras' identity in the right triangle , that is
BC² = AB² + AC² = 7.3² + 4.6² = 53.29 + 21.16 = 74.45 ( square root both sides )
BC = [tex]\sqrt{74.45}[/tex] ≈ 8.6 ( to 1 dec. place )
If Y is the midpoint of R and T. and RY = 3x - 2 and YT = 8x - 22. Find the
value of RT. *
Your answer
Answer:
11x-24
Step-by-step explanation:
All you have to do is add (3x-2)+(8x-22)=11x-24.
Answer:
RT = 20
Step-by-step explanation:
Since Y is the midpoint of RT , then
RY = YT , that is
3x - 2 = 8x - 22 ( subtract 8x from both sides )
- 5x - 2 = - 22 ( add 2 to both sides )
- 5x = - 20 ( divide both sides by - 5 )
x = 4
Then
RT = RY + YT = 3x - 2 + 8x - 22 = 11x - 24 , so
RT = 11(4) - 24 = 44 - 24 = 20
