Answer:

Solve for the first variable in one of the equations, then substitute the result into the other equation.

2x+y=20

6x-5y=12

First get y by its self

2x+y=20

y= -2x+20

Now plug into second equation for y

6x-5(-2x+20)=12

6x+10x-100

16x-100=12

16x=112

x=7

now plug in x value into first equation and solve for y

2(7)+y=20

14+y=20

y= 6

Now check by plugging x and y values back into equation

2(7)+6=20

6(7)-5(6)=12

They both work so x=7 and y =6

There were 436 tickets purchased for a major league baseball game. The general admission tickets cost ​$6.50 and the upper reser
Nataly [62]

Answer:

How many general admission tickets were​ purchased? __<u>136</u>__

How many upper reserved tickets we purchased? _<u>300</u>_

Step-by-step explanation:

Let the number of general tickets = g.

Let the number of reserved tickets = r.

6.5g + 8r = 3284

g + r = 436

     6.5g + 8r = 3284

(+)   -8g + -8r = -3488

--------------------------------

     -1.5g         = -204

g = 136

g + r = 436

136 + r = 436

r = 300

Answer:

How many general admission tickets were​ purchased? __<u>136</u>__

How many upper reserved tickets we purchased? _<u>300</u>_

A man throws a ball into the air with a velocity of 96 ft/s. Use the formula h=−16 t 2 + v 0 t to determine when the height of t
Ann [662]

Answer:

Assuming that v0 represents the initial velocity, then v0 = 96 ft/s. Substitute this value into h(t) and set the equation equal to 48. Then, write this quadratic equation in standard form, which is ax² + bx+ c = 0, where a, b, and c are constants. Either use factoring or the Quadratic Function to solve the equation for t. Remember that t must be positive, because it represents a unit of time.
