Answer:

$\boxed{x = -4}$

Step-by-step explanation:

This drawing illustrates the

equation: -3x – 7 = 5.

Since:

(-x + -x + -x) + (-1 + -1 + -1 + -1 + -1 + -1 + -1) =

(1 + 1 + 1 + 1 + 1) → (-3x) + (-7) = (5) →

-3x – 7 = 5.

To reduce the equation and find x:

[add 7 to both sides to isolate the constant term on the right side]

-3x – 7 + 7 = 5 + 7 →

-3x = 12 →

[divide both sides by -3 to cancel out the coefficient of -3 in -3x to get x]

-3x / -3 = 12 / -3 →

x = -4

Step-by-step explanation:

You are so smart. 5 - (-7) = 5+7 which = 12. 12/3 is 4.

This month, Chun’s office produced 690 pounds of garbage. Chun wants to reduce the weight of garbage produced to 85% of the weig

Effectus [21]

Chun wants to reduce the weight of garbage produced to 85% of the weight produced this month.
This means that, Chun's garbage weight next month should be equal to 85% of his garbage weight this month.

Translating this into an equation, we will find that:
garbage weight next month = 85% of garbage weight this month
garbage weight next month = 0.85 * garbage weight this month
garbage weight next month = 0.85*690
garbage weight next month = 586.5 pounds

Based on the above calculations, his target weight for the garbage next month is 586.5 pounds

Please helppp!! Find the missing side . Round to the nearest tenth

olga nikolaevna [1]

Answer:

7. 7.8

Step-by-step explanation:

We can use Tan of this angle to find the missing side (in this case, the side adjacent to the angle measuring 57°)

Tan A = (opposite side)/(adjacent side)

Tan 57° = 12/x

solve for x

x(Tan 57°) = 12
