What is the value of y in the equation 4y – 2(1 – y) = –44?
Sergio039 [100]

Answer:

-7

Step-by-step explanation:

To find y, follow these steps:

4y - 2 (1 - y) = -44

First, distribute the -2 into the parenthesis:

4y - 2 + 2y = -44

The reason the 2y is positive is due to the fact that negative and negative cancel each other out and form a positive.

Now, combine like terms:

6y - 2 = -44

To get y, you need to isolate it from the constants. In order to do so, do the inverse relationship for the constant -2. To do this, add 2 to -44:

6y = -42

Now, divide six on both sides. You divide because six is currently being multiplied with y. Keep in mind that the 42 is still negative!

y = -7

Hope this helps!

Help me solve # 15 & 16
makkiz [27]

Answer:

15) C=frac{5}{9}(F-32)

16) 12 hours

Step-by-step explanation:

15) F=\frac{9}{5}C+32 \\F-32 = \frac{9}{5}C\\\frac{5}{9}(F-32)=C

16) If Jim drove 168 mi in 4 hours, this means it takes him

\frac{4 hours }{168 mi}

this many hours to drive 1 mile. So if we multiply this by 504 mi:

\frac{4 hours }{168 mi} 504 mi = 4 \cdot 3 hours = 12 hours
