Create 2 eq’n, let V = vans and B= buses

1. 150 = 8v + 14b
2. b + v = 15

isolate one variable and substitute it in to an equation:

b = 15 - v

sub “b” into first equation above:

150 = 8v + 14 ( 15 - v)
150 = 8v + 210 - 14v
-60 = -6v
10 = v

sub “v” into equation 2

b = 15 - v
b = 15 - (10)
b= 5

there will be 5 buses and 10 vans to hold 150 students.

How do i solve this because I need some help. I'm studying for my test.

At Gino's you pay $16 plus $8 per pizza.
At Venetian's you pay $24 plus $6 per pizza.
Let the number of pizzas be x.

At Gino's you pay 16 + 8x
At Venetian's you pay 24 + 6x

Set the two costs equal and solve for x to find out the number of pizzas for which both costs are the same.

16 + 8x = 24 + 6x
16 + 2x = 24
2x = 8
x = 4
Each place gives you a free pizza.
4 pizzas plus the free pizza equals 5 pizzas.

If you need 5 pizzas (including the free one), both parlors cost the same.

If you need fewer than 5 pizzas, use Gino's.
If you need more than 5 pizzas, use Venetian's.

6) What happens to the diameter of the field of view as the magnification increases?
Diano4ka-milaya [45]

Answer:

There is an inverse relationship between the total magnification and the diameter of the field of view – i.e., as magnifications increases the diameter of the field decreases in proportion, so the diameter of field of view at different magnification can be calculated mathematically, using the formula.
