Answer:

x=27

Step-by-step explanation:

simplify 1/4

(1/4*x)-7=0

7=7/1=7*4/4

x-(7*4)/4=x-28/4

x-28/4=0

x-28/4*4=0*4

x-28=0

add 28 to both sides of the equation

x=28

PLEASE HELPP MEE!!!! MATH!!! PLEASEEE HELP ME!!!!!
IRISSAK [1]

Answer:

The solution is (3,2)

Step-by-step explanation:

x - y = 1 →equation 1

-x + 3y = 3 →equation 2

by elimination method,

x - y = 1

-x + 3y = 3

-----------------

0 + 2y = 4

2y = 4

y = 4/2

y = 2

substitute y=2 in equation 1

x - y = 1

x - 2 = 1

x = 1 + 2

x = 3  

∴(3,2) is the solution

In the given figure find the value of x and y if AB parallel to CD
liberstina [14]

Answer:

x = 42

y = 38

Step-by-step explanation:

for y:

there is a corresponding angle at 58° so y + 20 must equal to 58. ∴y = 38°

for x :

first locate the straight angle at CD. The angle opposite 58° must also be 58° as it is vertically opposite. We have two values here.. 58° and 22°. Use your knowledge of straight angles and add 22 + 58, which equals to 80. Now subtract from 180 which = to 100°. We know that the angle sum of a Δ is 180° so add 38 and 100, which will give you 138°. Subtract from 180 to give you a total of 42°

Sorry if this was very lengthy haha

hope it helps:)
