Answer:

<h2>x = - 1.106</h2>

Step-by-step explanation:

0.3(10-5x)=31.5(8x+9)

<u>Expand the terms in the bracket</u>

That's

3 - 1.5x = 252x + 283.5

<u>Subtract 3 from both sides</u>

3-3 - 1.5x = 252x + 283.5 - 3

-1.5x = 252x + 280.5

<u>Subtract 252x from both sides</u>

That's

- 1.5x - 252x = 252x - 252x + 280.5

- 253.5x = 280.5

<u>Divide both sides by -253.5</u>

We have the final answer as

x = - 1.106

Help plz only one question and the ans will come 100 ,100 ,80 of each angle

salantis [7]

z° = 80° (Being corresponding angles)

y° + 80° = 180° (Being linear pair of angles)

=> y° = 180° - 80°

=> y° = 100°

x° = y° (Being interior opposite angles)

=> x° = 100°

Help I need to get this done I have 15 questions

Answer:

8 cm

Step-by-step explanation:

(See the image attached for details)

The blue segment measures 15 cm
The green segment measures 7 cm
The green and yellow segment when added form the blue segment
So: ? + 7 = 15

Solve:

? + 7 = 15

Subtract 7 on both sides:

? + 7 = 15

-7 -7

? = 8 cm

Therefore, the yellow segment, or the missing side length, measures 8 cm.
