1. Solve the system by substitution.

zubka84 [21]

Answer:

The required solution is (0.128,13.82)

Step-by-step explanation:

Consider the provided system of equation.

$-2.5x+y=13.5$ ......(1)

$12.25x - y=-12.25$ ......(2)

We need to solve the system of equation by substitution method.

Consider the equation 1.

$-2.5x+y=13.5$

$y=13.5+2.5x$ ......(3)

Substitute the value of y in equation 2.

$12.25x - (13.5+2.5x)=-12.25$

$12.25x-13.5-2.5x=-12.25$

$9.75x-13.5=-12.25$

$9.75x=-12.25+13.5$

$9.75x=1.25$

$x\approx 0.128$

Now substitute the value of x in equation 3.

$y=13.5+2.5(0.128)$

$y\approx 13.82$

Hence, the required solution is (0.128, 13.82)

A local amusement park charges $21.50 per daily adult ticket and $14.75 per daily child's ticket. A group of 12 people paid $204

grandymaker [24]

Answer:

$x+y=12$

$21.50x+14.75y=204$

Step-by-step explanation:

Let x be the number of adult tickets and y be the number of children's tickets.

We are given that there are total 12 people. Therefore, we can set:

$x+y=12$

Moreover, we are given that an adult ticket costs $21.50 and a child's ticket costs $14.75, therefore, cost of x adult tickets will be $21.50x$ and cost of y children's ticket will be $14.75y$ . We can form the second equation by setting the total cost of tickets as:

$21.50x+14.75y=204$

Therefore, the required system of equations that could be used to find x and y will be:

$x+y=12$

$21.50x+14.75y=204$

In a fish tank, there are 3 orange fish, 5 blue fish and 6 yellow fish. In simplest form, what is the ratio of yellow

Lemur [1.5K]

Answer:

B. 2:1, for every two yellow fish there is one orange fish

Step-by-step explanation:

So you have 6 yellow fish and 3 orange fish.

You can divide both these values by 3 to get:

2 yellow fish: 1 orange fish

Therefore, the simplified version of the ratio is 2:1

In context this means for every 2 yellow fish there is 1 orange fish.

The answer is then B.
