Hey there!

g(x) = 3x - 2

y = 3x - 2

12 = 3x - 3

3x - 3 = 12

ADD 3 to BOTH SIDES

3x - 3 + 3 = 12 + 3

CANCEL out: -3 + 3 because it give you 0

KEEP: 12 + 3 because it give you the value of the x-value

NEW EQUATION: 3x = 12 + 3

SIMPLIFY IT!

3x = 15

DIVIDE 3 to BOTH SIDES

3x/3 = 15/3

CANCEL out: 3/3 because it give you 1

KEEP: 15/3 because it help solve for the x-value

NEW EQUATION: x = 15/3

SIMPLIFY IT!

x = 5

Good luck on your assignment and enjoy your day!

Overline MD cong overline LS additional information is necessary to show that triangle MTD cong triangle LGS by SSS?

aivan3 [116]

Answer:

$TD \cong GS$

Step-by-step explanation:

See comment for complete question

Given:

$TM \cong GL$

$MD \cong LS$

Required

The information that shows $\triangle MTD \cong \triangle LGS$ by SSS

By SSS implies that, the three sides of both triangles are congruent

Already, we have:

$TM \cong GL$

$MD \cong LS$

The third side of $\triangle MTD$ is $TD$

The third side of $\triangle LGS$ is $GS$

So, for both to be congruent by SSS, the third sides must be congruent

i.e.

$TD \cong GS$

A bottle holds exactly 2/3 pint of liquid. How many 2/3-pint bottles can be filled from a 24-pint container

kifflom [539]

Answer:

36 number of 2/3-pint bottles can be filled from a 24-pint container

Step-by-step explanation:

Volume of the container is 24 pint

Volume of the bottle is 2/3 pint

Number of 2/3 pint bottles that can be filled from 24 pint container is

$\frac{24}{\frac{2}{3} } \\= 24 * \frac{3}{2} \\= 12 * 3\\= 36$

36 number of 2/3-pint bottles can be filled from a 24-pint container

Math can anyone help me

dangina [55]

Answer:

C. $\frac{4}{10}$ and $\frac{10}{25}$

Step-by-step explanation:

The proportion between these fractions is true. Multiply 4/10 (numerator and denominator) by 2.5 to get 10/25. This is the only correct option.

Hope it helps!
