ss7ja [257]2 years ago
5 0

Answer:

Step-by-step explanation:

Both parts of the ratio can be divided by 9

81/9 = 9

72/9 = 8

The ratio is 9:8

54/48 is also 9:8

54 / 6 = 9

48/6 = 8

The ratio is 9:8

63:56 is also an answer

63 / 7 = 9

56/7 = 8

The ratio  is 9:8

The others don't work. You can just look at them to see why.

Answer:

  x = 16

Step-by-step explanation:

The angle bisector divides the sides proportionally.

  (x -4)/9 = x/12

  4(x -4) = 3x . . . . . . . multiply by 36

  x = 16 . . . . . . . . . . . . add 16-3x to both sides, simplify

Please help me ASAP it’s times THANK U

Answer:

Only choices C and D are solutions

Step-by-step explanation:

6x + 3y = -15

y = -2x - 5

6x + 3y = -15

6x + 3(-2x - 5) = -15

6x - 6x - 15 = -15

0 = 0

Since 0 = 0 is a true statement, both equations of this system are the same equation and represent a single line on the coordinate plane.

We need to check each choice in just one equation.

Let's use the second equation.

y = -2x - 5

A.

(2, 7)

7 = -2(2) - 5

7 = -4 - 5

7 = -9   False

Not a solution

B.

(5, 0)

0 = -2(5) - 5

0 = -10 - 5

0 = -15     False

Not a solution

C.

(-3, 1)

1 = -2(-3) - 5

1 = 6 - 5

1 = 1   True

Solution

D.

-13 = -2(4) - 5

-13 = -8 - 5

-13 = -13    True

Solution

Answer: Only choices C and D are solutions

How do I solve 3x+17 greater than or equal to (you can’t do the sign on a phone but it would be _>) 5
Kobotan [32]
<h3><u>The value of x is greater than or equal to -4.</u></h3>

(3x + 17) ≥ 5

Subtract 17 from both sides.

3x ≥ -12

Divide both sides by 3.

x  ≥ -4
