malfutka [58]
Find the common denominator for 3 and 10 which is 30 now the denominator is 30 and what you do with one side you do to the other so 6 7/10 turns into
6 21/30 and 2 1/3 turns into 2 10/30 now subtract them so 6 21/30-2 10/30=

Which expression is equivalent to this expression? x(2x 3) Question 1 options: 2x2 3 2x2 3x 2x2−3x 3x 3.
mash [69]

The expression is equivalent to this expression is  2x^2+3x.

The correct option is A.

Given

The expression is;

= x(2x + 3)

<h3>What is the algebraic expression?</h3>

Algebraic expressions consist of numbers and variables along with operational signs.

The equivalent expression is found by multiplying x and simplifying.

Therefore,

The expression is equivalent to this expression is;

\rm = x(2x + 3) \\\\= 2x\times x+ 3 \times x\\\\= 2x^2+3x

Hence, the expression is equivalent to this expression is  2x^2+3x.

If x=(10-3i) and y=(3-10i), then xy=? and x/y=?
Solnce55 [7]

Answer:

xy=-109i

\frac{x}{y}=\frac{60}{109}+\frac{91}{109}i

Step-by-step explanation:

xy=(10-3i)(3-10i)

To compute x times y must use foil on the right hand side.

First:  10(3)=30

Outer: 10(-10i)=-100i

Inner: -3i(3)=-9i

Last: -3i(-10i)=30i^2=-30

------------------------------------Add like terms:

-109i

----------------

\frac{x}{y}

\frac{10-3i}{3-10i}

Multiply top and bottom by bottom's conjugate:

\frac{(10-3i)(3+10i)}{(3-10i)(3+10i)}

Foil the top and just do first and last of Foil for the bottom since the bottom contains multiplying conjugates:

\frac{30+100i-9i-30i^2}{9-100i^2}

Replace i^2 with -1:

\frac{30+91i+30}{9+100}

\frac{60+91i}{109}

\frac{60}{109}+\frac{91}{109}i

A pitcher contains 40 fluid ounces of tea Shelby pour 3 cups of tea how many pints are left
Nastasia [14]

Answer:

1 pint of tea left in the pitcher.

Step-by-step explanation:

A pitcher contains 40 fluid ounces

1 cup = 8 fluid ounces

3 cups = 3*8 = 24 fluid ounces

After pouring tea in 3 cups,

tea left in pitcher = 40 - 24 = 16 fluid ounces

1 pint = 16 ounces

Therefore, 1 pint left.

Hope this will helpful.

Thank you.
