\text{Number of Votes Cast for Each Candidate:}
Number of Votes Cast for Each Candidate:
Candidate Votes
Candidate A 35
Candidate B 49
Candidate C 28
For every (blank)
votes cast for Candidate B, there were (blank )
votes cast for Candidate A.
Answer:
For every 7 votes cast for Candidate B, there were 5 votes cast for Candidate A.
Step-by-step explanation:
Given:
Candidate Votes
Candidate A 35
Candidate B 49
Candidate C 28
To find:
For every (blank) votes cast for Candidate B, there were (blank ) votes cast for Candidate A
Solution:
First we have to find the ratio of B and A
B : A
49 : 35
Now lets simplify the above ratio:
reduce the ratio using greatest common factor (GCF).
Use factorization method:
Write the numbers 35 and 49 as the product of their divisors.
The factors of 35 are: 1, 5, 7, 35
This means 35 is divided by 1, 5, 7 and 35 itself
The factors of 49 are: 1, 7, 49
This means 49 is divided by 1, 7 and 49 itself
Both have 7 common in them
Hence the greatest common factor is 7.
Next, divide both terms i.e. 35 and 49 by the greatest common factor, 7
49 / 7 = 7
35 / 7 = 5
The ratio 49 : 35 can be reduced to lowest terms by dividing both terms by the greatest common factor GCF = 7
So,
49 : 35 = 7 : 5
Hence
For every 7 votes cast for Candidate B, there were 5 votes cast for Candidate A.

If P(-9, -4), Q(-7, -1), R(-2, 5), S(-6, -1) are the coordinates of the points, what is the slope of line PQ?
Given :
P(-9, -4), Q(-7, -1), R(-2, 5), S(-6, -1).
To Find :
The slope of line PQ.
Solution :
We know , slope is given by :
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}\\\\m=\dfrac{-9-(-7)}{-4-(-1)}\\\\m=\dfrac{2}{3}[/tex]
Therefore, the slope of line PQ is 2/3.
Hence, this is the required solution.

pls ansswer the below question
Answer:
7 and 3
Step-by-step explanation:
Numbers are x and y, where x > y
Half the difference = 2
(x - y)/2 = 2 ⇒ x - y = 4The sum of the greeter number and the twice the smaller number is 13
x + 2y = 13Considering x = y+4 in the second equation
y + 4 + 2y = 133y = 13 - 43y = 9y = 3Then
x = y + 4x = 3 + 4 = 7The numbers are 7 and 3
Answer:7 and 3
Step-by-step explanation:
X-y=2×2
X-y=4
2x+y=13
2x+y-x-y=9
2x-x+y-y=9
X=3
3-y=4
3+4=7
Y=7

If you take 10^3/10^5 x 10^4 and simplify it, you would get 1/10^ x 10^4. Then you reduce the expression to 10^2, or in alternate form, 100.
How many cubic feet is the volume of a room with dimensions
10% ft x 102ft x 8ft?
Answer:
882 cubic ft.
Step-by-step explanation:
10.5 x 10.5 = 110.25
110.25 x 8 = 882 ft
Answer:
the volume of a room = 882 ft³
Step-by-step explanation:
given;
dimensions of a room 10 1/2 ft. x 10 1/2 ft. x 8 ft.
find:
volume
volume = L x W x H
let L = 10 1/2 ft.
W = 10 1/2 ft.
H = 8 ft.
plugin values into the formula:
V = 10.5 x 10.5 x 8
V = 882 ft³
therefore,
the volume of a room = 882 ft³

What is the solution to the system of linear equations?
-8x-7y=96
-3x+5y=-25
Enter your answer in the boxes
Answer:
[tex]x = -5[/tex]
[tex]y = -8[/tex]
Step-by-step explanation:
Given
[tex]-8x - 7y = 96[/tex]
[tex]-3x + 5y = -25[/tex]
Required
Determine x and y
Make y the subject of formula in the second equation
[tex]-3x + 5y = -25[/tex]
[tex]5y = 3x - 25[/tex]
[tex]y = \frac{3}{5}x - \frac{25}{5}[/tex]
[tex]y = \frac{3}{5}x - 5[/tex]
Substitute this value in the first equation
[tex]-8x - 7(\frac{3}{5}x - 5) = 96[/tex]
[tex]-8x - 7*\frac{3}{5}x + 7 * 5 = 96[/tex]
[tex]-8x - \frac{21}{5}x + 35 = 96[/tex]
Collect Like Terms
[tex]-8x - \frac{21}{5}x = 96 - 35[/tex]
[tex]\frac{-61}{5}x = 61[/tex]
[tex]x = 61 * \frac{-5}{61}[/tex]
[tex]x = -5[/tex]
Recall that
[tex]y = \frac{3}{5}x - 5[/tex]
This gives
[tex]y = \frac{3}{5} * -5 - 5[/tex]
[tex]y = -3 - 5[/tex]
[tex]y = -8[/tex]
