If you are looking for the values of X, they are 2/3, 9/4

3x+2=0

3x=2

X=2/3

4x-9=0

4x=9

X=9/4

If you are looking for the multiplication, it is on this picture:

$3 for 6 bagels; $9 for 24 bagels.Determine if the rates or ratios are equivalent
Luba_88 [7]
No these are not equivelent.  24 is 4x6 so that would mean that you would have to pay $12 for those bagels and because 9 is not 3x4, 12 is making these two ratios not equivelent.

The measures of two supplementary angles are (4x + 8) and (6x + 3)º.
Illusion [34]

Step-by-step explanation:

A supplementary angle is an angle that is 180 degrees. We are given two angles that add up to 180, but we need to solve for x first.

The first step is to solve both angles. We know that both angles added together are supplementary, so they are equal to 180.

4x + 8 = unknown angle

6x + 3 = unknown angle

(4x + 8) + (6x + 3) = 180

Because we know a supplementary angle is 180 degrees, we can solve for x to find both angles.

Solve for x.

(4x + 8) + (6x + 3) = 180

10x + 11 = 180

10x = 169

x = 16.9

Now, we know the value of x, so we plug in x for both angles to determine which angle is smaller.

4x + 8

4(16.9) + 8

67.6 + 8 = 75.6 degrees

and the other angle

6x + 3

6(16.9) + 3

101.4 + 3 = 104.4 degrees

Now we know that the smaller angle is 75.6 degrees.

Also, to make sure the math is correct, when plugging in both numbers after finding x, they should add to 180.

75.6 + 104.4 = 180 so we know they are supplementary for sure.

Good luck!

lara31 [8.8K]
The possibilities are:

bbbb

bbbg

bbgg

bggg

This shows that there is a 1 in 4 chance of having three boys and one girl

So the answer could be 1/4 or a 25% chance
