Beck add like terms so you get
4x^2 -4x-15
lucy factor our negative so you left with -4x^2 +5x -10 +8x^2 -9x -5
simplify 4x^2 -4x -15
therefore both students answers simplify to 4x^2 -4x -15

LenKa [72]

Answer:

v < -11

Step-by-step explanation:

  1. Combine like terms: 3v - 5v > 12 + 10
  2. Simplify: -2v > 22
  3. Divide each side by -2 to cancel out the -2 next to v. It should now look like this: v < -11

I hope this helps!

How many hours did I work if I worked 7 hours and 30 minutes a day, for 15 days?
baherus [9]

Answer:

112 hours and 50 mins

Step-by-step explanation:

Numbers of mins worked in a day = 7×60+30 =450 mins

Now number of mins worked in 15 days = 450×15

= 6750 mins

to convert mins into hours divide by 60

6750÷60 = 112.50

that means total number of hours worked in 15 days = 112 hours and 50 mins

vodomira [7]

Answer:

x = 25.8^{o} and y = 51.4^{o}

Step-by-step explanation:

Known that he sum of angles on a straight line is 180^{o}. From the diagram;

2y + x + y = 180^{o}

x + 3y = 180^{o} ................ 1

Also,

2x + x + 2y = 180^{o}

3x + 2y = 180^{o} .............. 2

Using the elimination method, multiply equation 1 by 3 and equation 2 by 1

3x + 9y = 540 ............ 3

3x + 2y = 180^{o} ............. 4

7y = 360

y = \frac{360}{7}

y = 51.4^{o}

substitute the value of y in equation 1,

x + 3y = 180^{o}

x + 3(51.4) = 180^{o}

x + 154.2 = 180^{o}

x = 180^{o} - 154.2

x = 25.8^{o}

Thus, x = 25.8^{o} and y = 51.4^{o}
