8 divided by 2 is 4, so multiply 3/4 by 2, 6/8, than you have your answer, 6.
15/50 * 2/2 = 30/100
Now you can easily see decimal and percent form
Decimal: 0.30
Percent: 30 percent
Answer:
Step-by-step explanation:
Angles 153 and QRP are straight angles, and thus Angle QRP is
180 - 153, or 27 degrees.
The interior angles of the triangle must sum up to 180 degrees:
27 + (3y + 5) + (2y - 7) = 180.
combining like terms, we get:
5y - 25 = 180, or 5y = 155, or y = 31
Then Angle Q is 3(31) + 5, or 93
Angle P is 2(31) - 7, or 55, and
Angle QRP is 27 degrees (found earlier).
