Answer:
-4/7
Step-by-step explanation:
The first step of this problem would be changing the format of the equation so that it fits into slope-intercept form.
-4x = 7y + 13
-4x -7y = 13 (subtract 7y from both sides)
-7y = 4x + 13 (add 4x to both sides)
7y = -4x -13 (divide both sides by -1)
y = -4/7x - 13/7 (divide both sides by 7)
Now that it is in slope-intercept form, finding the slope is simple as long as you know what to look for.
Remember that y is simply a variable, just because it is at the beginning of the equation does not mean -4/7x - 13/7 is the answer. The question is asking specifically for the slope of the line. Slope in this equation is m. If y = mx + b, then m = -4/7.
The slope of the line is -4/7.

an electric wire which is 0.12 m long is cut into 3 pieces of the same length.How long is each pieces?
Answer:
0.04m
Step-by-step explanation:
0.12/3=0.04
Answer:
Step-by-step explanation:
Total length of a wire = 0.12 m
If the wire is divided into 3 equal pieces then
Length of each piece
= 0.12 / 3
= 0.04 m

The angles of a triangle add up to 180 degrees.
The second angle is 20 degrees larger than the smallest angle.
The third angle is 3 times as big as the smallest angle.
Find the measure of the smallest angle (in degrees)
Answer: 32 degrees
Step-by-step explanation:
small angle : x
middle angle: x + 20
large angle: 3x
Form an equation: 5x + 20 = 180
5x = 180 - 20
5x = 160
x = 160/5
x = 32

Answer:
[tex]Opposite =- \frac{4}{5}[/tex]
Step-by-step explanation:
Given
[tex]Number = \frac{4}{5}[/tex]
Required
Determine its opposite
To get the opposite of a number, we simply subtract it from 0.
So, we have:
[tex]Opposite =0 - \frac{4}{5}[/tex]
[tex]Opposite =- \frac{4}{5}[/tex]
Hence, the opposite is -4/5

Answer:
12.3
Step-by-step explanation:
18% of the the students at a school are in year 8 and 16% of the students are in year 9. If the school has 126 tera 8 students, determine the number of year 9 students.
Answer:
112
Step-by-step explanation:
The general form of all percentage questions is: the chunk= (some percentage) (of the whole), or c=p*w
We know that 18% of students are 8th grade and that is 126 students, so p = 0.18 and c=126 (126 students are 18% of the whole school)
126 = (0.18)w, divide both sides by 0.18
126/(0.18) = w = 700
9th graders are 16% of the school or 16% of 700 students
c = (0.16) 700 = 112 students
What are the values of s and t?
Answer:
I think t is 72, because the angle looks equal to the known degree, which is 72. And since all the degrees have to add up to 180, 72+72 is 144 and 180-144 is 36. So angle s is 36 degrees.
m∠FDC=124°; m∠EAB=2x, m∠ACG=4x. Find: x, m∠ACD
Answer:
x=28 degrees
Step-by-step explanation:
4x = 28*4 = 112
180 degrees - 112 = 68
ACD = 68

3+(55-111)/25 equals what
Answer:
0.76
Step-by-step explanation:
3+(55-111)/25
=3+(-56)/25
=3+ (-2.24)
=0.76
Answer:
3+(55-111)/25= 0.76
Step-by-step explanation:
Using PEMDAS, you solve 55-111 which is -56
Then you divide -56 by 25 because it is the fourth step, you get -2.24
Add three to -2.24 to get 0.76
If you round UP to the nearest tenth, it will be 0.80
If you round DOWN to the nearest tenth, it will be 0.70
