-6x + 3y = 910x + 4y = -6​

Mathematics
1 answer:
Stells [14]3 years ago
8 0

Step-by-step explanation:

(-6x +3y=9 )×4

( 10x+4y)×3

-24x +12y =36

30x+12y= -18

-24x+12y- (30x+12y)= 36-(-18)

-54x = 54

x= -1

by using 10x +4y = -6

apply x= -1

-10+4y= -6

4y= -6 +10

4y=4

y=1

so the answer is x=-1 and y= 1

The sum of three consecutive numbers is 72 what is the smallest of the numbers
mylen [45]

Answer:

23

Step-by-step explanation:

Suppose,

the first number = x

the second number = x+1

the third number = x+1+1 = x+2

Question wise,

x+x+1+x+2 = 72

3x+3 = 72

3x = 72-3 = 69

x = 69/3 = 23

so the numbers are,

23,(23+1)=24 and (23+2)=25

The perimeter of a rectangle is 44 inches. If the width of the rectangle is four more than half the length, find the length of t
Mars2501 [29]

Answer: the length of the rectangle is 12 inches

Step-by-step explanation:

Let the length of the rectangle is x inches

Hence, the width is (x/2)+4 inches

Thus,

\displaystyle\\2(x+(\frac{x}{2} +4))=44\\\\2x+x+8=44\\\\3x+8=44\\\\3x+8-8=44-8\\\\3x=36\\

Divide both parts of the equation by 3:

x=12\ inches
