I need someone to explain on how to do this problem.

weqwewe [10]

Answer:

I think it's x=-12 for the buttom one

Step-by-step explanation:

I think when you get open equations like these you would asume 1 is there so rewrite it as 2x + 25 = 1

so take the 25 away from 1. to do that we need to do the opisite of +

2x + 25 = 1

1 - 25 = -24

rewrite

2x = -24

take the 2 away. oppisite of mulitplication is division. so divide 2 by -24

-24 divided by 2 = -12

Hope this helps! Please mark as brainliest! Thanks! If you need me to solve the top one too, I'll do it! Just comment bellow. :D

PLEASE HELP ASAAAAPPPPPPP

Distribute ^4 to both 2 and q^5

2^4 = 2 x 2 x 2 x 2 = 16
(q^5)^4 = q^20

16(q^20) = 16q^20

16q^20 is your answer

hope this helps

On a coordinate plane, 2 quadrilaterals are shown. The first figure has points A (negative 2, 1), B (negative 4, 1), C (negative

The rule of reflection is ry-axis (x , y) → (-x , y) ⇒ 2nd answer

Step-by-step explanation:

Let us revise some transformation

If point (x , y) reflected across the x-axis , then its image is (x , -y) , the rule of reflection is rx-axis (x , y) → (x , -y)
If point (x , y) reflected across the y-axis , then its image is (-x , y) , the rule of reflection is ry-axis (x , y) → (-x , y)

∵ The first quadrilateral has vertices

A (-2 , 1) , B (-4 , 1) , C (-4 , 5) , D (-2 , 4)

∵ The second quadrilateral has vertices

A' (2 , 1) , B' (4 , 1) , C' (4 , 5) , D' (2 , 4)

- The x-coordinates of point A' , B' , C' , D' have the same values

and opposite signs of the x-coordinates of points A , B , C , D

∴ A' , B' , C' , D' are the images of A , B , C , D after reflection

across the y-axis

∴ The rule of reflection is ry-axis (x , y) → (-x , y)

The rule of reflection is ry-axis (x , y) → (-x , y)

mayflies can live at the bottom of lakes for 2 to 3 years before they become winged adults.Mayflies are between 4/10 inches and

Airida [17]

To simplify any fraction, look for a common factor in the top number
and the bottom number. If you find one, divide the top and bottom
both by their common factor. Eventually, you reach the point where
their only common factor is ' 1 ' ... that's when it's in simplest form.

4 and 10 both have 2 as a factor.

When you divide top and bottom both by 2, you have 2/5 .
This is the simplest form of 4/10 .

None of this has anything to do with mayflies. You can use the same
process to simplify fractions in ANY situation where fractions arise.
