x-7/4 =-2 I need helpp

Answer:

(x,y)=(-1,-4)

Step-by-step explanation:

-4x + y = 0

+4x         +4x

y=4x

-5x - 2y = 13

+5x          +5x

-2y = 5x+13

-2(4x) = 5x+13

-8x=5x+13

-5x -5x

-13x/-13=13/-13

x=-1

Thus:

y=4x

y=4(-1)

y=-4

The answer would be -7/12

Step-by-step explanation:

What you would do is

a/b×c/d=ac/bd

this would be the formula

so what you would do is -7 (which is the numerator X the other numerator which equals -7 times 1= -7

then you would do 2 X6= which is 12 so the answer would be 7/12 because you can't simplify it anymore

Answer:

[tex]a=\frac{K}{4+9b}[/tex]

Step-by-step explanation:

[tex]K=4a+9ab[/tex]

Switch sides:

[tex]4a+9ab=K[/tex]

Factor out a:

[tex]a\left(4+9b\right)=K[/tex]

Divide both sides by: [tex](4+9b)[/tex]

[tex]\frac{a\left(4+9b\right)}{4+9b}=\frac{K}{4+9b}[/tex]

[tex]a=\frac{K}{4+9b}[/tex]

add up all the numbers which equals 300 then divide but the amount of numbers in this is 6 so that gives you 50

Answer:

50 is the mean

Step-by-step explanation:

When it ask for mean it ask you to add up all the numbers and divide by how many numbers their are. Their 6 numbers added together to make the total of 300.

49+51+49+51+51+49 = 300

300 / 6 = 50

Answer:

False

Answer:

PQ = 1 ft

QR = 4 ft

Step-by-step explanation:

From the picture attached,

Segment PR has been divided into two parts by a point Q.

Length of segment PR = 5 feet

Length of segment PQ = (15x - 2) ft

Length of segment QR = (5x + 3) ft

Since, PR = PQ + QR

5 = (15x - 2) + (5x + 3)

5 = 20x + 1

20x = 4

x = [tex]\frac{4}{20}[/tex]

x = 0.2

PQ = 15x - 2

     = 15(0.2) - 2

     = 3 - 2

     = 1 ft

QR = 5x + 3

     = 5(0.2) + 3

     = 1 + 3

     = 4 ft

Answer:

Step-by-step explanation:

If an elephant charged 13.3 meters in 15 seconds, to calculate the distance charged by the elephant in one minute, the following steps will be arried out.

15 seconds = 13.3 meters

1minute (60 seconds) = x

cross multiply

15 * x = 13.3 * 60

15x = 798

Divide both sides by 15

15x/15 = 798/15

x = 53.2metres

Hence the elephant will charge 53.2 meters for 1 minute

Answer:

.125 of a mile

Step-by-step explanation:

If the total distance was 3/8 of a mile and there were 3 runners, then each runner ran ___________________.

Change the 3/8 to a decimal

3/8 = 0.375 of a mile

Since there were 3 runners divide the total distance by 3

0.375/3 = 0.125

Each runner ran 1/8 of a mile or 0.125 of a mile.
