A) 5x - 30x² = 0<br> Solve each equation by factoring
Fynjy0 [20]

Answer:

x=0     x = 1/6

Step-by-step explanation:

5x  -30x^2 = 0

Factor out the greatest common factor which is 5x

5x(1 -6x) =0

Use the zero product property

5x =0  and 1-6x =0

x =0                -6x = -1

                           x = -1/-6

                         x = 1/6

Find the value of x and y. Triangle MNP = triangle TUS
xenn [34]

Answer:

x = 32, y = 51

Step-by-step explanation:

Since the triangles are congruent then corresponding sides and angles are congruent, that is

∠ U = ∠ N

∠ N = 180° - (142 + 24)° = 180° - 166° = 14° , then

2x - 50 = 14 ( add 50 to both sides )

2x = 64 ( divide both sides by 2 )

x = 32

and

NP = US

2x - y = 13

2(32) - y = 13

64 - y = 13 ( subtract 64 from both sides )

- y = - 51 ( multiply both sides by - 1 )

y = 51

6 - 3x = 5x - 10x + 8
Jet001 [13]

Answer:

x=1

Step-by-step explanation:

6-3x=5x-10x+8=

move all terms to the left:

6-3x-(5x-10x+8)=0

add all the numbers together, and all the variables

-3x-(-5x+8)+6=0

get rid of parentheses

-3x+5x-8+6=0

add all the numbers together, and all the variables

2x-2=0

move all terms containing x to the left, all other terms to the right

2x=2

x=2/2

x=1
