What is the value of y?
lord [1]

Answer:

15

Step-by-step explanation:

Angle c is 180 - 146 = 34

All 3 angles add to 180:

(5y + 3) + (4y + 8) + 34 = 180

9y + 45 = 180

9y = 135

y = 15

Can someone please help me?
Katyanochek1 [597]
The matrix represents the system:

-3x+5y=15

2x+3y=-10, which is choice c. 


We can see it more clearly from the way we multiply matrices, as follows:

\[
  \left[ {\begin{array}{cc}
   -3 & 5 \\
    \ 2  & 3 \\
  \end{array} } \right]
\] \cdot  \[
  \left[ {\begin{array}{c}
   x \\
    y \\
  \end{array} } \right]
\]= \left[ {\begin{array}{c}
   -3\cdot x+5\cdot y \\
    2\cdot x+3\cdot y \\
  \end{array} } \right]
\]= \[ \left[ {\begin{array}{c} 15 \\ -10 \\ \end{array} } \right] \]

Answer: C

Hannah can paint a room in 8 hours. Destiny can paint the same room in 6 hours. How long does it take for both Hannah and Destin
Ksivusya [100]

Answer:

3 hours 26 minutes

Step-by-step explanation:

1/8 + 1/6 = 1/t  where t is the required time in hours.

Multiply through by 24t:-

3t + 4t = 24

7t = 24

t = 3 3/7 hours

or  3 hours 26 minutes to the nearest minute.
