Answer:

First option: 2

Step-by-step explanation:

Check each answer:

8 < x(7-x)

8 < 2(7-2)

8 < 2(5)

8 < 10

True

8 < x(7-x)

8 < 8(7-8)

8 < 8(-1)

8 < -8

False

8 < x(7-x)

8 < -1(7-(-1))

8 < -1(7+1)

8 < -1(8)

8 < -8

False

8 < x(7-x)

8 < 0(7-0)

8 < 0

False

Therefore, 2 is the only correct solution out of the given answer choices.

Answer:

Step-by-step explanation:

Ratio=3:4

so,the pair of adjacent sides are 3x,4x

Pythagorean theorem,

$(3x)^{2}+(4x)^{2}=20^{2}\\9x^{2}+16x^{2}=400\\\\25x^{2}=400\\\\x^{2}=\frac{400}{25}\\\\ x^{2}=16\\\\x=\sqrt{16}\\\\x=4\\\\length=4x=4*4=16cm\\\\breadth=3x=3*4=12cm\\\\Perimeter=2*(l+b)\\\\=2*(16+12)=2*28\\\\=56cm$

Annabelle the ant and Archibald the ant are on a large coordinate grid. Annabelle is at (3,4) and Archibald is at (33,44). If bo

kvasek [131]

Part a) If both ants skate directly towards each other, starting at the same time and skating the same speed, what will be the coordinates of their meeting place?

Let

A(3,4) B(33.44)

we know that

If both ants skate directly towards each other, starting at the same time and skating the same speed

then

the coordinates of their meeting place is the midpoint AB

Find the midpoint AB

in the x-coordinate

(3+33)/2=18

in the y-coordinate

(4+44)/2=24

the midpoint AB is (18,24)

therefore

the answer Part a) is

the coordinates of their meeting place is (18,24)

Part b) How far will each ant skate?

Find the distance AB

$d=\sqrt{(x2-x1)^{2}+(y2-y1)^{2}}$

substitute the values

$dAB=\sqrt{(33-3)^{2}+(44-4)^{2}}$

$dAB=\sqrt{2,500}$ units

$dAB=50$ units

Find the half distance AB

50/2=25 units

therefore

the answer part b) is

Each ant will skate 25 units

How do I find what x equals

Jobisdone [24]

Answer:

basically, you get x to one side and the number to another side, then simplify. For example, 3x-2=x+6. The steps are:

2x-2=6, here we brought the x to the other side by subtracting an x from each side. Since the x was positive (adding) we subtract x from each side.

2x=8, we did the same thing but added 2 to each side since -2+2=0, and now it is on the other side.

x=4, 2x means x times 2, so you would divide each side by 2.

In short, put x on one side and number on the other by doing the opposite of what something says, remove multiplication or division by doing the opposite. You must always do it on both sides, or it is not an equation.
