57 plus what equals 86

adult ticket = 10

child ticket = 4

Step-by-step explanation:

for example…

so that we get a system of equations

9x + 5y = 110…Equation 1

x + y = 14…Equation 2

solve the system of equations, this time I will use the Elimination and Substitution method

9x + 5y = 110

x + y = 14 (multiplied by 5)

↓↓↓↓↓↓↓

9x + 5y = 110

5x + 5y = 70

___________ _

4x = 40

x = 10

to find value of y subtitute x to one of Equation. for example from second Equation…

x + y = 14

10 + y = 14

y = 14 - 10

y = 4

∴ So, the number of each ticket was she bought is 10 adult ticket and 4 child ticket.

Answer:

- 22

Step-by-step explanation:

3(-4) - 5(2)

-12 - 10

- 22

Answer:

-22

Step-by-step explanation:

3(-4) = -12

5(2) =  10

-12-10 =-22

Answer:

option B ................

is the correct answer

Answer: x = 7

Step-by-step explanation:

Subtract both sides by 3

X+3-3 = -4 - 3

X+0 = -7

X=-7

Answer:

-7

Step-by-step explanation:

x+3=-4

x=-4-3 (subtract 3 from both sides)

x=-7 (combine like terms)

Answer:

20 Pints

Step-by-step explanation:

If there are 8 pints in 1 gallon of water, then multiply 8 by 2.5 to get 20 pints of water.

Answer:

Your answer is ( -1, 3 ).

Hope this helps!

Step-by-step explanation:

y - 3 = 2 ( (-1) +1 )

y - 3 = 2 ( 0 )

y - 3 = 0

y = 3

if 9m away from deep point, m1 also away from 9m to radius line.

so if we draw 2 x 2y to 1 half side of circle, y is connected with 9m, x is connected to 6m.

2 x = 150 sec

if i say 1 x 6m 2x 12m

x =75 sec =12.5 sec

(2x +2y ).2 is whole circle round

12.5*15*2

Answer:

f(3) = 100

Step-by-step explanation:

Using the recursive formula and f(1) = 1 , then

f(2) = - 10 f(1) = - 10 × 1 = - 10

f(3) = - 10 f(2) = - 10 × - 10 = 100

Answer:

I got x = 20

Step-by-step explanation:

what i did was 8x - 25 = 7x -5, i then did  8x - 25 + 5 = 7x -5 +5 then you get 8x - 20 = 7x  I then did 8x - 20 -8 = 7x -8 you would get -20 = -1x or -x and -20/-1 = x = 20 I hope this works : )

Answer:

the formulaA= 12BH is use to know the surface area of the triangle prism

Answer:

D

Step-by-step explanation:

The range is all of the y values that make a function true. Our graph here starts at y=-2 and then goes up for infinity. This means the range is y ≥ -2. The domain is [0, ∞) because our x values start at 0 and go to infinity. This means the domain is restricted so A is not true, B is not true because the graph does not exist at x = -2.

Answer:

x=-8

Step-by-step explanation:

An undefined slope is a vertical line, and the equation for one is always x=(Whatever number x is at those points).

Therefore, with our point of (-8, 2), the equation must be x=-8
