Answer:

Step-by-step explanation:

I chose C because it depends how much money the school has. So it wouldn’t be 5 or 12, because we don’t know how much money the school has to buy how many basketballs. Tell me if I’m wrong.

Fed [463]

The answer should be 4.

Divide 20 by 2. Thus then you subtract 6.

Your final answer is 4.
$20 \div 2 - 6$

(y + 5)(y – 9) = 0<br> need help asap!!

OLEGan [10]

Set each equation equal to zero.

y + 5 = 0

Subtract 5 from both sides.
y = 0 - 5
y = - 5

y - 9 = 0

Add 9 to both sides
y = 0 + 9
y = 9

y = - 5, 9

27x823 do the math and explain give brainleast

Step2247 [10]

Answer:

22221

Step-by-step explanation:

I set up the problem like this

823

x27

Then I multiplied 7 by 3 and carried over the one and then multiplied 7 by 2 and added one and carried the one over... I then multiplied 7 by 8 and added the one!

Then I put a zero where the 7 I first multiplied would be... I then multiplied 2 by 3 and then multiplied 2 by 2 and finally multiplied 2 by 8!

I then added up the two values! (Sorry this probably sounds confusing!)

For what values are 2x^2=10x

BARSIC [14]

$\\ \sf\longmapsto 2x^2=10x$

Take to to right

$\\ \sf\longmapsto x^2=\dfrac{10x}{2}$

$\\ \sf\longmapsto x^2=5x$

Cancel a x from both sides

$\\ \sf\longmapsto x=5$

Which expression is equivalent to 1/2x+(−7)−2 1/4x−(−2

Lynna [10]

The equivalent expression to the given expression is $\mathbf{=-(\dfrac{7}{4}x+5)}$

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

Algebraic expressions are mathematical expressions. They usually consist of one or more variables with their coefficients and arithmetic operators such as: (division, multiplication, addition, and subtraction).

From the given expression, we are to determine an expression that is equivalent to:

$=\dfrac{1}{2}x + (-7) -2 \dfrac{1}{4}x -(-2)$

To do this, we are going to simplify the above-given expression to its lowest term since we are not given any options to choose equivalent expressions from.

By doing so, we have:

$=\dfrac{1}{2}x -7 -\dfrac{9}{4}x +2$
