Bad White [126]3 years ago
5 0

Answer:

a = -8

Step-by-step explanation:

you can solve this proportion by cross-multiplying:

4(a + 9) = -1(a + 4)

now distribute to eliminate parentheses

4a + 36 = -1a - 4

5a + 36 = -4

5a = -40

a = -8

Solve: 3 x ≤ 6 how do I do this plz help
timama [110]

Answer:

  x ≤ 2

Step-by-step explanation:

Most of the properties of equality also apply to inequalities. The exception is multiplication (or division) by a negative number. An equation can be multiplied or divided by any number you like (except division by 0) and it will remain true. <em>An inequality must have the relation symbol reversed when multiplying or dividing by a negative number</em>.

Here, we don't run into that issue, because we can solve this by dividing both sides by the coefficient of x, which is +3.

  (3x)/3 ≤ 6/3

  x ≤ 2 . . . . . . . simplify

Following from greatest to least 5 * 10 ^ 3 3.2 * 10 ^ 8 1.2 * 10 ^ 8 7 * 10 ^ 5
Zina [86]

Answer:

3.2*10^8>1.2*10^8>7*10^5>5*10^3

Step-by-step explanation:

5*10^3 = 5000

3.2*10^8=320000000

1.2*10^8=120000000

7*10^5=700000

320000000>120000000>700000>5000

therefor

3.2*10^8>1.2*10^8>7*10^5>5*10^3
