The answer is B because it is the only one where the line intersects on the y - axis at -1/2 and 2/3, which are the y -intercepts

What is the answer to this somebody!!!
Galina-37 [17]

So with this, you'll be using a proportion to solve it. And here's what your equation will look like:


\frac{30}{x} =\frac{x}{24}


Firstly, you'll need to cross-multiply. Your equation will look like this: 720=x^2


For this, all you need to do is square root, and your answer is \sqrt{720} =x, however this answer can be simplified further.


\sqrt{720} =\sqrt{30*24} =\sqrt{5*6*6*4}=\sqrt{5*3*2*3*2*2*2} =4*3\sqrt{5} =12\sqrt{5}


In short, your answer is 12\sqrt{5}

A kindergarten teacher bought $21 worth of stickers and cardstock for his class. The stickers cost $1.50 a sheet and the cardsto
Georgia [21]

Answer:

Done

Step-by-step explanation:

Teacher bought $21 worth of stickers and cardstock for his class.

Cost of stickers = $1.50 per sheet

Cost of 's' sheets = $1.5s

Cost of cardstock = $3.50 per pack

Cost of 'c' packs = $3.5c

Equation representing the relationship between sheet of stickers and packs of cardstocks will be,

1.5s + 3.5c = 21

3.5c = -1.5s + 21

1).  

  y-intercept of the line → (0, 6)

  x-intercept of the line → (14, 0)

  Therefore, equation of the line represents the line on the graph.

2). Vertical intercept (0, 6) represents that he can purchase maximum 6 packs of cardstock with $21.

  Similarly, horizontal intercept (14, 0) represents that he can purchase maximum 14 sheets of stickers with $21.

22x+102x(5+23)8=(24+90)
zubka84 [21]

Answer:

Answer x= 57/ 11435

Step-by-step explanation:

Let's solve your equation step-by-step.

22x+102x(5+23)(8)=24+90

Step 1: Simplify both sides of the equation.

22x+102x(5+23)(8)=24+90

22x+22848x=24+90

(22x+22848x)=(24+90)(Combine Like Terms)

22870x=114

22870x=114

Step 2: Divide both sides by 22870.

22870x

22870

=

114

22870

x=

57/ 11435
