Can someone pls help find x and y

Mathematics

VLD [36.1K]2 years ago

Answer:

x = 9 & y = 29

Step-by-step explanation:

Since we know that 7x is next to 117, that area will be equal to 180*,

7x + 117 = 180

7x = 180-117

7x=63

x=9

to find y, you can use the same method, just by finding the other angle inside. 53+7(9) + z = 180

53+63 = 180

116+z = 180

z = 180-116

z = 64.

Then we do

4y + 64 = 180

4y = 180-64

4y=116

y = 29

HES<br> LO)<br> What is the solution to the equation -(5-(a+1)) = 9-(5-(2-3))?<br> TESI
diamong [38]

Solution for given equation -(5-(a+1)) = 9-(5-(2-3)) is a = 7

<u>Solution: </u>

Need to determine solution of following equation’

-(5-(a+1)) = 9-(5-(2-3))

Means need to solve the above equation for "a"

On solving operation in most internal bracket we get  

-(5-(a+1)) = 9- ( 5 – ( -1))  

On opening inside brackets we get,

-(5 – a – 1 ) = 9 – ( 5 +1 )  

On solving remaining brackets we get

-5 + a + 1 = 9 – 6

=> a – 4 = 3

=> a = 4 + 3 = 7

=> a = 7

Hence solution for given equation -(5-(a+1)) = 9-(5-(2-3)) is a = 7

Calculate The Constant of Proportionality (k) and Write an Equation for the line in the Graph Below:
S_A_V [24]

Answer:

k = ½

Equation => y = \frac{1}{2}x

Step-by-step explanation:

Constant of proportionality (k) = y/x

Using a point on the graph, (6, 3),

k = y/x = 3/6 = ½

k = ½

Equation of the line:

Plug in the value of k into y = kx (slope-intercept form of equation for proportional relationship)

Thus:

y = \frac{1}{2}x
