Given 2x - 9y - 12 = 0, express 5x - 4y + 7 = 0 in terms of x only

olga2289 [7]

Answer:

$4 \frac{1}{9}x$ + $12\frac{1}{3}$ = 0

Step-by-step explanation:

Based on 2x - 9y - 12 = 0

-9y = 12 - 2x

9y = -12 + 2x

y = $-1\frac{1}{3} + \frac{2}{9} x$

Therefore...

5x - 4y + 7 = 0

5x - 4( $-1\frac{1}{3} + \frac{2}{9} x$ ) + 7 = 0

5x + $5\frac{1}{3}$ - $\frac{8}{9} x$ + 7 = 0

$4 \frac{1}{9}x$ + $12\frac{1}{3}$ = 0

The sum of three consecutive even integers is 36. Let x represent the least consecutive integer.

lubasha [3.4K]

The integers are x, x + 2 and x + 4

x + x + 2 + x + 4 = 36
3x + 6 = 72
3x = 36 - 6 = 30
x = 30/3 = 10

The least numbers is 10
Therefore, the numbers are 10, 12 and 14

Quick it is due in 30 mins plz do quick

Answer:

1. 69°

2. 97°

3. 145°

4. 150°

5. 128°

6. 74°

Step-by-step explanation:

To find the angle measure of the missing angle, we have to note that the angle measures of a quadrilateral will all equal up to be 360°.

If we know 3 out of the 4 angles and the sum of the angles, we can add up the angles we know then subtract that from 360.

Number 1:

$87+112+92=291$

$360-291=69$

Number 2:

$124+71+68=263$

$360-263=97$

Number 3:

$95+46+74=215$

$360-215=145$

Number 4:

$72+49+89=210$

$360-210=150$

Number 5:

$69+65+98=232$

$360-232=128$

Number 6:

$77+123+86=286$

$360-286=74$

Hope this helped!
