Answer:
b = 5
Step-by-step explanation:
to get b, you see that is multiplied by 7. to get rid of the 7, you have to divide both sides by 7. this is because 7/7 = 1, so you would just have b. then, 35/7 equals 5, and it is on the other side of the equal sign, so you would have b = 5.
Answer:
The correct option is last one 77 degrees.
Therefore the measure angle W is 77 degrees.
Step-by-step explanation:
Given:
Exterior angle = 122°
∠W = (2x-13)°
∠Y= x°
To Find:
∠W = (2x-13)° = ?
Solution:
Exterior Angle Property:
An exterior angle of a triangle is equal to the sum of the opposite interior angles.
Angle W and Angle Y are the interior angles of Exterior angle 122°.
∴ 
Substituting the values we get

Now Substitute 'x' in angle W we get

Therefore the measure angle W is 77 degrees.
Answer: 130
Step-by-step explanation:
Let x be the original number of hip- hop CDs in the music store.
Given : A music store has sold 3/5 of their hip-hop CDs, but 10 were returned.
i.e. The number of hip- hop CDs in the store will be :
Original No. of CDs - CDs sold + CDs Returned

If the store has 62 Hip-Hop CDs now , then required euation will be :-

Subtract 10 from both sides , we get




Hence, the number of CDs they originally have = 130
Answer:
XY = 8 and YZ = 20
Step-by-step explanation:
If XY and YZ are on the one line, we can write
XY + YZ = 28
(2x+2) + (9x - 7) = 28
2x+2 + 9x - 7 = 28
11x - 5 = 28
11x = 33
x = 3
XY = 2x+2 = 2*3 + 2 = 8
YZ = 9x - 7 = 9*3 - 7 = 27 - 7 = 20
