Answer:

6:9

Step-by-step explanation:

Lets assume the relationship between the amount of blue and red marbles are proportional. If there are 6 red marbles , then we would need need to find out how much times you multiplied 2 by to get.

6/2 is 3, which means that you multiplied the red marbles by 3 to get 6 of them.

Since the relationship between red and blue marbles is equivalent, we just need to multiply the blue marbles by 3 as well, to even it out.

3x3=9

There are 9 blue marbles if there are 6 red marbles.

2. Each side of a pentagon is the same size.

4cm x 5 = 20cm or 4cm+4cm+4cm+4cm+4cm = 20cm

3. Each side of a square is the same size.

13yd x 4 = 52yd or 13yd+13yd+13yd+13yd = 52yd

4. Add all sides together.

12m+12m+30m+30m = 84m

5. Again add all sides together.

16yd+16yd+4yd+4yd = 40yd

6. Each side of a square is the same size.

7in x 4 = 28in. or 7in+7in+7in+7in = 28in

7. Add all sides together.

2cm+2cm+3cm+3cm = 10cm

8. Each side of a rhombus is the same size. A rhombus has 4 sides.

23in x 4 = 92in or 23in+23in+23in+23in = 92in

9. A regular octagon has 8 sides and each side is the same size.

9cm x 8 = 72cm

Solve for all values of x by factoring. x^2-5x=-2x

-Dominant- [34]

Answer:

x = 0

x = 3

Step-by-step explanation:

$x^2 - 5x = -2x\\x^2 - 5x + 2x = 0\\x^2 - 3x = 0\\x(x - 3) = 0\\x=0 , x-3=0\\x=0, x=3$

Please solve asap pls x

Answer:

$x=\frac{26}{5}$

Step-by-step explanation:

$\frac{10x+4}{7}=8$

Multiply both sides by 7:

$\longmapsto$ $\frac{7\left(10x+4\right)}{7}=8\times \:7$

$\longmapsto$ $10x+4=56$

Subtract 4 from both sides:

$\longmapsto$ $10x+4-4=56-4$

$\longmapsto$ $10x=52$

Divide both sides by 10:

$\longmapsto$ $\frac{10x}{10}=\frac{52}{10}$

$\longmapsto$ $x=\frac{26}{5}$
