We need to complete square
x²-2*3x+3²=7+3²
x²-6x+9 =7+9
(x-3)² = 16
√(x-3)²=+/-√16
x-3=+/-4
x-3=4 and x-3=-4
x=7,    Largest

-x=-24 <br> it’s for pre-algebra
labwork [276]
So -x can also represent -1

You want to divide both sides by -1 so you can get -x to be just x

-x divided by -1 = x
-24 divided by -1 = 24

Your answer is x=24

William buys two bags of peaches and three bags of apricots for $17. Sylvia buys four bags of peaches and two bags of apricots f
Rus_ich [418]

Answer: One bag of peaches : $22

Step-by-step explanation:

Hi, to answer this question we have to write an equation for William and Sylvia.

  • <em>William: 2 p + 3 a = 17 </em>
  • <em>Silvia: 4p + 2 a =22 </em>

Where:

p = price of one bag of peaches

a= price of one bag of apricots

Solving for "a" in William's equation:

2p +3a =17

3a = 17-2p

a = (17-2p)/3

a= 17/3 -2/3 p

Replacing "a" in Silvia's equation

4p + 2 a =22

4p + 2 (17/3 -2/3p) =22

4p +34/3-4/3p =22

4p-4/3p =22-34/3

8/3 p =32/3

p =32/3 ÷8/3

p=4

Please solve if you know no trolls please im desparate
IgorC [24]
The question isn’t equal to 90° it’s equal to 180° because the line is straight it’s not a right angle. so when u equal the whole equation to 180°, you get x=18.75. then plug in the number to find the degree of each.
so angle of department would be 139.25° and angle of gas station would be 40.75°
