Answer:

1. w = 15

2. b = 4.8

3. s = 9.7

4. p =15

5. m = -3.2

Step-by-step explanation:

1.w + 10 = 25

we have to find the value of w, so moving 10 from left side to right side

w= 25 - 10

w = 15

2. 7.2 + b = 12

we have to find the value of w, so moving 7.2 from left side to right side

b= 12 - 7.2

b= 4.8

3. 5.3 + s = 15

s= 15 - 5.3

s= 9.7

4.p + (-25) = -10

p-25 = -10

p= -10 + 25

p= 15

3. m + (-1.6) = -4.8

m - 1.6 = -4.8

m = -4.8 + 1.6

m= -3.2

Answer:

1. w=15

2. b=4.8

3. s=9.7

4. p=15

5. m=-3.2

Step-by-step explanation:

1. For the equation w + 10 = 25, subtract 10 from both sides:

w + 10 -10= 25-10\\w=15

2. For the equation 7.2 + b = 12 subtract 7.2 from both sides:

7.2 + b -7.2= 12-7.2

b=4.8

3. For the equation 5.3 + s = 15  subtract 5.3 from both sides:

5.3 + s-5.3 = 15-5.3\\s=9.7

4. For the equation p + (-25) = -10, multiply signs and then add 25 to both sides of the equation:

p -25= -10\\p - 25 +25= -10+25\\p=15

5. For the equation  m + (-1.6) = -4.8,  multiply signs and then add 1.6 to both sides of the equation:

m -1.6+1.6 = -4.8+1.6\\m=-3.2

Anit [1.1K]
Let 0.25x is the price increase. Therefore, the number of attendees will be 350-10x and the revenue R=(350-10x)*(5+0.25x)=1750+37.5x-2.5x^2. This parabola has maximum at x=10, meaning the price=7.5
