Abriana claims that the solution to the system of linear equations y = 2x – 1 and –12x + 3y = 9 is (–2, –5). Select all methods
EleoNora [17]

Answer:

Substitution method can be used

Step-by-step explanation:

Given the system of equations

y = 2x-1 ....1

-12x + 3y = 9 ....2

The best method to use id the substitution method

Substitute equation 1 into 2;

From 2;

-12x + 3y = 9

-4x + y = 3

-4x + 2x-1 = 3

-2x -1 = 3

-2x = 3+1

-2X = 4

x = -4/2

x = -2

Substitute x = -2 into 1

y = 2x - 1

y = 2(-2)-1

y = -4-1

y = -5

Hence the solution to the system of equation is (-2, -5)

There are (4^2)^3 ⋅ 40 horses on a stud farm. What is the total number of horses on the farm?
Colt1911 [192]

If this is for real, the answer is 163,840 horses on the farm, because 4^2 is 16, and 16^3 is 4,096, and 4,096 times 40 is 163,840.

Tickets to the school musical are $5.00 for adults and $2.50 for students. If the total value of the tickets sold was $687.50 an
Masja [62]

Answer:

Your answers should be a = 135 adult tickets and s = 186 student tickets.

Step-by-step explanation:

1. Solving for variable s by manipulating variable a:

a + s = 321

a = 321 - s (subtract s to the other side to get a by itself)

$3.50(321-s) + $2.50s = $937.50 (substitution from step 2)

$1123.50 - $3.50s + $2.50s = $937.50 (distributive property)

$1123.50 - $1.50s = $937.50 (combine like terms)

-$1.00s = -$186 (subtraction property of equality)

s = 186 student tickets.

2. Solving for variable a by manipulating variable s:

a + s = 321

s = 321 - a

$3.50a + $2.50(321-a) = $937.50

$3.50a + $802.50 - $2.50 a = $937.50

$1.00a = $135

a = 135 adult tickets.

If you plug both numbers into the original equations, they should come out to be true equations. 135 + 186 = 321 and $472.5 + $465 = $937.5, so these two numbers are your answers for a and s accordingly.

Using the elimination method, we need to eliminate one of the variables by a process of subtraction or addition depending on the case. We can use multiplication or division before eliminating in order to eliminate.

a + s = 321

3.50a + 3.50s = 1123.50 (multiply entire equation by 3.50 in order to eliminate variable a by subtraction)

Now, we can use elimination:

3.50a + 3.50s = 1123.50

3.50a + 2.50s = 937.50

0a + 1s = 186, or s = 186 student tickets.

The same process can be used to solve for variable a. Your answers should be a = 135 adult tickets and s = 186 student tickets.
