Answer:

D. 55, 55, 125, 125

Step-by-step explanation:

To solve this problem we first need to know what the total degrees of a 4 angle quadrilateral is. The answer to this is 360°. Knowing this, we need to figure out which combination of numbers adds up to 360. To do this, I go through the list and check all of the options.

A.) 10+10+125+125=270

B.) 15+15+25+125=180

C.) 15+15+115+125=270

D.) 55+55+125+125=360

95 divided into 4524

I hope you mean 4524 divided by 95. That would look like this:4524/95. In that case, your answer would be a long decimal but rounded it would be: 47.62
If you mean 95/4524, then your answer would be: 0.00994

Answer:

A (-2,8) B (-1,5) C (-6,2)

A(-2,-7) B(-5,-8) C(-8,-3)

Step-by-step explanation:

x,y x,y x,y

A(7,-2) , B(8,-5) , C(3,-8)

translation (7-9),(-2+10) (8-9),(-5+10) ( 3-9),(-8+10)

(x-9) and (y+10) (-2,8) (-1,5) (-6,2)

when rotation 270 degrees counterclockwise around the origin:

A(x,y ) Then A'(-y,x) means switch x and y and make x negative

A(7,-2 ) rotation 270 degrees counterclockwise (-2,-7)

B(8,-5) to (-5,-8)

C(3,-8) to (-8,-3)

What is the solution to 4 (m-3) + 19 = 8 (2m + 3) + 7?

Flauer [41]

Answer:

x=-2

Step-by-step explanation:

Let m=x

$4(x-3)+19=8(2x+3)+7\\$

Expand the parentheses:

$4x-12+19=16x+24+7\\4x+7=16x+31\\-31+7=16x-4x\\-24=12x\\x=-2$
