Answer:
s= number of shirts
3/2= constant of proportionality
Step-by-step explanation:
Josh takes a load of dress shirts to the dry cleaners. The amount he pays for dry cleaning (
f. is given by the equation f=3/2s, where s is the number of shirts. What is the constant of proportionality in terms of the cost per shirt?
Given:
f= 3 / 2s
Where,
f= amount Josh paid for dry cleaning
s= number of shirts
3= constant of proportionality
2= amount paid per shirt
For example, if Josh took 3 shirts to the dry cleaner, the amount Josh will pay is
f= 3 / 2s
= 3 / 2(3)
= 3 / 6
= 1 / 2
f= 1 /2

Please help me with my homework my homework question
Answer:
(B) Subtract 3x from both sides of the equation, and then divide both sides by 2.
Can't read the second question fully.
(A) 0.53
Step-by-step explanation:
Number 1:
If we have the equation [tex]3x + 2 = 5x[/tex], our first goal is to get rid of the x term on one side.
To do this we can subtract 3x from both sides. This leaves our equation to [tex]2=2x[/tex]. To find x, we want to divide both sides by 2 since 2x divided by 2 is just x. Our goal is to isolate x. This leaves [tex]x=1[/tex].
I couldn't read Number 2 fully - I'm sorry :c
Number 3:
Given the equation [tex]3(x+0.2)=2.2[/tex], we want to isolate x on one side.
To do this, we first apply the distributive property to the left side.
[tex]3x + 0.6 = 2.2[/tex]
Now subtract 0.6 from both sides:
[tex]3x=1.6[/tex]
And divide both sides by 3.
[tex]x=0.5\overline{3}[/tex]
This rounds to 0.53.
Hope this helped!
Answer:
B
28.78
A
Step-by-step explanation:
Equation
3x + 2 = 5x
The first step is to subtract 3x from both sides.
3x - 3x + 2 = 5x - 3x
2 = 2x
The next step is to divide by two. That's the 2 in front of the two x.
2/2 = 2x/2
1 = x
So the answer must be B
The others are just not done in the right order and give wrong answers.

Sorry didn't see the other two.

carlos wants to buy some new video games. each game he buys costs $36. help carlos by writing an equation that represents his total price.
Answer:
36 × (how many games he buys) = (the price)
Step-by-step explanation:
36 dollars multiplied by the number of games he buys will equal the price.
Example:
Let's say he bought 3 games.
36 × 3 = 108
So, in this case, he bought three games using $108 .

Five times the sum of a number and 27 is greater than or equal to six times the sum of that num
solution set of this problem?
Question:
Five times the sum of a number and 27 is greater than or equal to six times the sum of that number and 26.
What is the solution set of this problem?
Answer:
[tex]x \leq -21[/tex]
Step-by-step explanation:
Given
Represent the number with x
So:
[tex]5 * (x + 27) \geq 6 * (x + 26)[/tex]
Required
Determine the solution set
[tex]5 * (x + 27) \geq 6 * (x + 26)[/tex]
Open Both Brackets
[tex]5 * x + 5 * 27 \geq 6 *x + 6 * 26[/tex]
[tex]5x + 135 \geq 6x + 156[/tex]
Collect Like Terms
[tex]5x - 6x \geq 156-135[/tex]
[tex]- x \geq 21[/tex]
Multiply both sides by -1
[tex]x \leq -21[/tex]
Hence, the solution set is [tex]x \leq -21[/tex]
Answer:
[tex]x\leq -21[/tex]

2/3c=18 what does c equal to
Answer: 27
Step-by-step explanation:
Answer:
c = 27
Step-by-step explanation:
Solve for c:
(2 c)/3 = 18
Hint: | Multiply both sides by a constant to simplify the equation.
Multiply both sides of (2 c)/3 = 18 by 3/2:
(3×2 c)/(2×3) = 3/2×18
Hint: | Express 3/2×2/3 as a single fraction.
3/2×2/3 = (3×2)/(2×3):
(3×2)/(2×3) c = 3/2×18
Hint: | Express 3/2×18 as a single fraction.
3/2×18 = (3×18)/2:
(3×2 c)/(2×3) = (3×18)/2
Hint: | Cancel common terms in the numerator and denominator of (3×2 c)/(2×3).
(3×2 c)/(2×3) = (2×3)/(2×3)×c = c:
c = (3×18)/2
Hint: | In (3×18)/2, divide 18 in the numerator by 2 in the denominator.
18/2 = (2×9)/2 = 9:
c = 3×9
Hint: | Multiply 3 and 9 together.
3×9 = 27:
Answer: c = 27
i dont unsterstand irrational numbers
An irrational number cannot be expressed as a ratio between two numbers and it cannot be written as a simple fraction because there is not a finite number of numbers when written as a decimal. Instead, the numbers in the decimal would go on forever, without repeating.
Answer:
Irrational number does not terminate and do not repeat. I hope this can make you understand what does irrational number is. Hope it helps you

Answer:
21). WX = 10
22). VW = 22
23). WY = 20
24). VX = 32
25). WZ = 30
26). VY = 42
Step-by-step explanation:
In the figure attached,
V, W, X, Y and Z are collinear.
VZ = 52, XZ = 20 and WX = XY = YZ
21). Since XZ = 20
XY + YZ = 20
WX + WX = 20 [Since, XY = WX = YZ]
2(WX) = 20
WX = 10
22). VZ = VW + WX + XY + YZ = 52
VW + 3(YZ) = 52 [Since, WX = XY = YZ]
VW + [tex]3(\frac{XZ}{2})[/tex] = 52
VW + [tex]\frac{3}{2}\times 20[/tex] = 52
VW = 52 - 30 = 22
23). WY = WX + XY
= 2(WX)
= 20
24). VX = VW + WX
= 22 + 10
= 32
25). WZ = 3(WX)
= 30
26). VY = VZ - YZ
= 52 - 10
= 42

First solve for x, then find ∡RQW. ∡WQP=139+x, ∡RQW=31+x & ∡RQP=152°
Answer:
[tex]x = -9[/tex]
[tex]RQW = 22[/tex]
Step-by-step explanation:
Given
[tex]WQP = 139 + x[/tex]
[tex]RQW = 31 + x[/tex]
[tex]RQP = 152[/tex]
Required
Determine x and WQP
From the attachment;
[tex]RQP = RQW + WQP[/tex]
Substitute 152 for RQP, 31 + x for RQW, 139 + x for WQP
[tex]152 = 31 + x + 139 + x[/tex]
Collect Like Terms
[tex]152 - 31 - 139 = x + x[/tex]
[tex]-18 = 2x[/tex]
Divide both sides by 2
[tex]\frac{-18}{2} = x[/tex]
[tex]x = -9[/tex]
To solve for RQW; substitute -9 for x in RQW = 31 + x
[tex]RQW = 31 + (-9)[/tex]
[tex]RQW = 31 -9[/tex]
[tex]RQW = 22[/tex]

Answer:
[tex]\Large \boxed{\mathrm{Point \ C}}[/tex]
Step-by-step explanation:
Point C is located 5 units from points M.
Point C : (-1, 6)
Point M : (-6, 6)
Distance between two points:
[tex]d=\sqrt{(x_2-x_1)^2 +(y_2-y_1)^2 }[/tex]
[tex]d=\sqrt{(-6-(-1))^2 +(6-6)^2 }[/tex]
[tex]d=\sqrt{(-5)^2 +(0)^2 }[/tex]

Answer:
1a. A
1b. C
2 and 3 you have to draw
4a. 90 degree angle
4b. 180 degree angle
5a. 112 degrees
5b. 145 degrees
Step-by-step explanation:
for 5 you just subtract the given values from 360
Answer:
1a) A
(both B and C intersect at A)
1b) not sure
2a) draw 270 degree angle
360/4 = 90
90+90+90 = 270 = 3/4
2b) draw an angle less than 90 degree to get an acute angle
3a) first draw a 90 degree angle then divide the angle into two half and you ll get an angle of 45 degrees
90/2 = 45
but since you re not allowed to use compass or protactor so you might not get exact 45 but near to it
3b) draw a 90 degree angle facing downward and thats 270 degree
hope you get what im trying to say if not you can ask me again
4a) acute angle (90 degree)
4b) reflex angle (180 degree)
5a) 112 degree
118 + 130 + x = 360
248 + x = 360
x = 360 - 248
x = 112
5b) 145 degree
360 - 215 = 145
im posting the solutions and the answers of your previous questions here
6a) a = 60 degree
6b) b = 27 degree
because sum of interior angles of a triangle is 180
7a) b = 60 degree and a = 30 degree
7b) x = 36 degree and x = 36 degree
isosceles triangle has 2 same angles and 1 different
x + x + 108 = 180
2x + 108 = 180
2x = 180 - 108
2x = 72
x = 72/2
x = 36
8a) x = 95 degree
8b) a = 100 degree
9) steps;
draw a line segment QR
draw 120 degree angle at point Q
now open the compass of 2cm (or of your own choice) and draw a small arc from point Q such that it intersects line PQ and QR and name that point between QR as O
now from point O, open your compass of same measurement and draw an arc that cuts the previous arc
now draw a line from point Q to join the new formed arc
now using a protactor measure both the newly formed angles
Step-by-step explanation:

Samantha conjectures that for x < -1, it is true that x5 - 2 > x. Is her conjecture correct? Why or why not?
Answer:
The conjecture cannot work for any negative numbers, It works for x > 1.3.
Step-by-step explanation:
An odd power preserves the sign. For |x| > 1, the power increases the magnitude. For x < 0, adding -2 only increases the magnitude more. A negative number of larger magnitude will not be "greater than" the reference. It will be "less than."
It only takes a counterexample to show the conjecture is incorrect.
x^5 -2 ?? x
(-2)^5 -2 ?? (-2)
-32 -2 ?? -2
-34 < -2 . . . . . . not greater than
