1 answer:

4 0

-1/3x < 48

Divide each side by -1/3. When you divide by a negative the sign flips...

x > 48 ÷ -1/3

divide fractions by multiplying the reciprocal of the divisor

x > 48 × -3
x > -144

yra solves the equation as shown. - 3(x+2) = 9 1. - 3x - 6 = 9 2. - 3x = 15 3. x = - 5 The property Tyra used in line 1 was the:

Molodets [167]

Answer:

Distributive property says that:

$a\cdot(b+c) = a\cdot b + a\cdot c$

Addition property of equality:

if x = y then x+z = y+z

Division property of equality:

if x = y then $\frac{x}{z}=\frac{y}{z}$

As per the statement:

Given the equation: $-3(x+2)=9$

Tyra solve this equation as shown below:

$-3x -6 = 9$ [Distributive property]

$-3x = 15$ [Addition property of equality]

$x = -5$ {Division property of equality]

Therefore, the property Tyra used in line 1 was : Distributive Property.

Answer:

Option C

The student's conclusion is correct because the solution to the system of equations $3x+2y=27$ and $2x+y=16$ is $(5,6)$

Step-by-step explanation:

Let

x------> the cost of each burger

y-----> the cost of each sandwich

we know that

$3x+2y=27$ -----> equation A

$2x+y=(27-11)$

$2x+y=16$ ----> equation B

Solve the system of equations

Multiply the equation B by $-2$

$-2(2x+y)=-2*16$ -----> $-4x-2y=-32$ ------> equation C

Adds equation A and equation C

$3x+2y=27 \\-4x-2y=-32\\ ----------\\ 3x-4x=27-32\\ -x=-5\\x=5$

Substitute the value of x in the equation B

$2(5)+y=16$

$10+y=16$

$y=6$

The solution of the system of equations is the point $(5,6)$

The price of each burger is $\$5$

The price of each sandwich is $\$6$
