What is the first step in solving 2x=y X+y=30
Vanyuwa [196]

Answer: x = 10 y=20

Step-by-step explanation:

You can answer this question by plugging in each equation:

2x=y, x+y=30. Let us plug y as 2x in the second equation x+y=30

x+2x= 30

3x= 30

x=10

After we found x we can then find y by plugging the 10 for x.

2(10) = y

y =20

or you could plug in the other equation

10+y=30

subtract 10 from 30 and we get 20

to double check we can plug in both numbers

2(10) = 20 which is correct

and 10 + 20 = 30 which is correct

A line has this equation : y = 9/4x + 9 Write an equation for the parallel line that goes through (12, 7) .
faltersainse [42]

Answer:

y=9/4x-20

Step-by-step explanation:

Do the parallel line equation

7=9/4(12)+b

Solve for b

7=9×12÷4+b

7=27+b

subtract 27 to both sides

-20=b

Parallel lines have the same slope

y=9/4x-20

rusak2 [61]

Answer:

100 ft^2

Step-by-step explanation:

The large upper rectangle has dimensions 12 ft by 23 ft, and thus has area 276 ft^2.  The small lower rectangle is 15 ft by (12 - 7) ft,  or 15 t by 5 ft, and thus has area 75 ft^2.  The total area is

75 ft^2 + 25 ft^2, or 100 ft^2.
