A line that includes the points (s, -9) and (5, -6) has a slope of -3. What is the value of s?
Answer:
s=6
Step-by-step explanation:
slope(m) = (y2-y1)/(x2-x1)
or, -3 = (-6+9)/(5-s)
or, -3(5-s) = 3
or, -15+3s = 3
or, 3s = 18
so, s = 6

Answer:
→Loss=Rs100
Step-by-step explanation:
Solution,
→CP of a quintal of potatoes=Rs4000
→Sp of a quintal of potatoes=Rs390 per 10kg
→SP of 1 kg of potatoes=rs390/10=Rs39
→SP of 100kg(a quintal)=Rs39 x 100=Rs3900
Here,
→SP<CP=Loss
→Loss=CP-SP
→Loss=Rs4000-Rs3900
→Loss=Rs100

A game charges $0.99 for custom skins and a $9.99 membership fee. Write and expression that gives the
total cost in dollars for c number of skins and a membership.
Answer:
y=0.99c+9.99
Step-by-step explanation:
its 0.99 so you got to times it by the number since we have no number we are using the letter c as a substitute then add the membership fee
Answer:
0.99c + 9.99
Step-by-step explanation:
We know one part of the expression is going to be $0.99c, since it's $0.99 per custom skin, and c is the number of custom skins were getting.
Then we must add on the 9.99 on top of that, since that is the one-time membership fee. This is what the equation looks like :
0.99c + 9.99

The value of y is equal to 2 when x is equal to - 10.
What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
Assuming x = ky.
When y = - 5, x = 25.
25 = - 5k.
k = - 5.
Now, x = - 10 and k = - 5.
∴ - 10 = - 5y.
y = 2.

(10.) The sum of the 6th and 8th terms of an
arithmetic progression is 142. If the fourth
term is 49, find the first term, the common
difference and the sum of the first seven
terms of the progression.
Answer:
first term: 27common difference: 7 1/3sum of 7 terms: 343Step-by-step explanation:
The general term of an arithmetic sequence is ...
an = a1 + d(n -1)
Using the given information, we can write two equations in a1 and d:
a6 +a8 = 142 = (a1 +d(6 -1)) +(a1 +d(8 -1)) = 2a1 +12d
a4 = 49 = a1 +d(4 -1) = a1 +3d
__
Subtracting twice the second equation from the first, we get ...
(2a1 +12d) -2(a1 +3d) = (142) -2(49)
6d = 44
d = 44/6 = 22/3 = 7 1/3 . . . the common difference
Subtracting the first equation from 4 times the second gives ...
4(a1 +3d) -(2a1 +12d) = 4(49) -142
2a1 = 54
a1 = 54/2 = 27 . . . the first term
_____
The sum of the first n terms of the progression is ...
Sn = (2·a1 +d(n -1))(n/2)
The sum of the first 7 terms is ...
S7 = (2·27 +22/3(7 -1))(7/2) = (54 +44)(7/2) = 343 . . . sum of 7 terms

Find the value of x.
The value of x is ____
Answer: 26.5°
Step-by-step explanation:
First angle: 180 - (x + 16) = 180 - x - 16 = (164 + x)°
Second angle: 180 - (3x - 1) = 180 - 3x + 1 = (181 - 3x)°
Third angle: (180 - 5x)°
Fourth angle: (180 - 6x)°
Seeing that the sum of angles in any given quadrilateral is 360°,
(164 + x) + (181 - 3x) + (180 - 5x) + (180 - 6x) = 360
164 + x + 181 - 3x + 180 - 5x + 180 - 6x = 360
705 - 13x = 360
345 = 13x
x = [tex]26\frac{7}{13}^{o}[/tex]
x = 26.5° (1dp)
EL 25% DE 75 ES 20 DIGANME POR FABOR
Answer:

Cuanto es 25% de 75?
Para calcular este tanto por ciento, sugerimos usar esta fórmula:
% / 100 = Parte / Total
Sustituyendo los valores proporcionados:
25 / 100 = Parte / 75
Realizando la Multiplicación en cruz:
25 x 75 = 100 x Parte, o

Parte = 1875 / 100 = 18.75
Which ratio is equivalent to 2:1?
A: 1:2
B: 10:5
C: 1:3
D: 2:1
Answer:
B: 10:5.
Step-by-step explanation:
To find equivalent ratios, multiply both sides by the same number.
Equivalent ratios:
Multiplied by 2: 4:2
Multiplied by 3: 6:3
Multiplied by 4: 8:4
Multiplied by 5: 10:5
Multiplied by 6: 12:6
Multiplied by 7: 14:7
Option A is incorrect, the ratio is the opposite of 2:1.
Option C is incorrect, the ratio isn't equivalent to 2:1.
Option D is incorrect, it's the same ratio as 2:1. Not a different, equivalent ratio.
Option B is correct, it's one of the equivalent ratios supported above.
