Answer:

70 adults

42 children

Step-by-step explanation:

A + C = 112

A = 112 - C

2.25A + 1.75C = 231

2.25(112 - C) + 1.75C = 231

252 - 2.25C + 1.75C = 231

21 = 0.5C

C = 42

A = 112 - C

A = 112 - 42

A = 70

Answer:

42 child and 70 adult

Step-by-step explanation:

Let a = number of adult tickets

c = number of child tickets

a+c = 112

2.25a + 1.75c = 231

Solve the first equation for a

a = 112-c

Substitute this into the second equation

2.25(112-c) + 1.75c = 231

Distribute

252 - 2.25c +1.75c = 231

Combine like terms

252 -.5c = 231

Subtract 252 from each side

252-252 -.5c = 231-252

-.5c = -21

Divide each side by -.5

-.5c/-.5 = -21/ -.5

c = 42

Now can find a

a = 112-c

a = 112-42

a = 70

Answer:

B

Step-by-step explanation:

Well you can get rid of c and d since 9^2 = 81. so 74 is less than 81 so it's definitely less than 9. Now, we know it's between 8 and 9. try multiplying 8.5 x 8.5 = 72.25. So our ranges are

A) 64 - 72.25

B) 72.25 - 81.

74 falls between 72.25 - 81. So it'll be B

Andy wrote the equation of a line that has a slope of Step 2: y plus 2 equals StartFraction 3 Over 4 EndFraction x minus StartFr
Archy [21]

Andy's equation is incorrect and the correct equation of the line is y + 2= 3/4(x - 3)

<h3>How to determine the equation of the line?</h3>

The given parameters are:

Slope, m = 3/4

Point, (x,y) = (3,-2)

The equation of the line is calculated using:

y - y1 = m(x - x1)

Substitute the known parameters

y + 2= 3/4(x - 3)

From the question;

Andy's equation is y + 2 = 3/4(x - 9/4)

The above equation is different from the actual equation y + 2= 3/4(x - 3)

Hence, Andy's equation is incorrect and the correct equation of the line is y + 2= 3/4(x - 3)
