Answer:

11x=1

Step-by-step explanation:

15x+4=5+3x+1x       Bring everything with an x in front of it to the left side

15x-3x-1x+4=5         Simplify the x values

11x+4=5                    Bring the 4 to the right side

11x=5-4

11x=1

Ganezh [65]

Answer:

1924.3

Step-by-step explanation:

Ok

You need to write an expression for the change in value

the change is linear, so you will get a line equation y = mx + b

y-axys : value

x-axys : years

New Hampshire:

Slope = \frac{133300-37600}{2000-1950} = 1914

the y-intercept will be 37600 because you can assume that 1950 = 0, and 2000 = 50

y = 1914*x + 37600

Massachussets:

Slope = \frac{185700-55400}{2000-1950} = 2606

Same as above, the y-intercept is 55400

y = 2606*x + 55400

Now you need to equal the value for both and find the year "x"

1914x + 37600 = 2606x + 55400

- 692x = 17800

x = -25.7

Since i considered x = 0 to be 1950; the actual year is 1950 - 25.7 = 1924.3

2x+2y=6<br><br>3x-5y=25 <br><br>oooooooooooooooooooooooooooooooooooooooooooooooooo
marta [7]

Solve for x in 2x + 2y = 6

x = 3 - y

Substitute x = 3 - y into 3x - 5y = 25

9 - 8y = 25

Solve for y in 9 - 8y = 25

y = -2

Substitute y = -2 into x = 3 - y

x = 5

Thus,

<u>y = 5</u>

<u>y = -2</u>
