use cross products

5*(y-5) = 3*(y-7)

distribute

5y-25 = 3y-21

subtract 3y from each side

2y-25 = -21

add 25 to each side

2y = 4

divide by 2

y=2

Twice the sum of a number and 8 is the same aa the difference of 3 and the number. Find the equation that could be used to find
Nezavi [6.7K]

Answer:

f your number is x, then the difference between that number and 8 would be x-8. Twice that is 2(x-8)

 

Three times the sum of the number and 3 would be 3(x+3). So, you get the equation:

 

2(x-8)=3(x+3)

2x-16=3x+9

x=-25

Polygon ABCDEF has 6 sides. A is 170° C is 133° D is 102° he is 117° and F is 90°. What is the measure of b?
Zielflug [23.3K]

Answer:

B = 134^o

Step-by-step explanation:

n = 6 --- sides

A = 170^o

C = 107^o

D = 102^o

E = 117^o

F = 90^o

Required

The measure of B

The interior angles of a polygon is:

Angles = (n - 2) * 180

So, we have:

Angles = (6 - 2) * 180

Angles = 4 * 180

Angles = 720^o

The measure of B is calculated using:

A + B + C + D + E + F = 720

Substitute known values

107 + B + 170 + 102 + 117 + 90 = 720

Collect like terms

B + 107 + 170 + 102 + 117 + 90 = 720

B + 586 = 720

Collect like terms

B = 720 - 586

B = 134^o

How do you convert a mixed number 3 3/5 to an improper fraction?
oee [108]
Multiply 3 by the denominator, then add the numerator. Then we keep the original denominator. 
So we get:
3 x 5 = 15 + 3 = 18
we get:
18/5
