Remember
anything times 1=same thing and
 
x/x=1 where x=x
so
mutliply both fractions by what makes the bottom numbers 40
1/5
5 times what=40?
answer is 8
multily by 1 or 8/8
1/5 times 8/8=8/40


7/8
8 is bottom
8 times what is 40? answer is 5
multiply by 1 or 5/5
7/8 times 5/5=35/40
1/5=8/40
7/8=35/40
they are not equal

No because you multiply 1/5 by 8 ans you will get 8/40 mean while you got 7/8 and multiply that by 5 and you get 35/40 so the answer is no

stealth61 [152]

Answer:

x = \frac{2}{3}

Step-by-step explanation:

Equate f(x) and g(x) , that is

- 3x + 4 = 2 ( subtract 4 from both sides )

- 3x = - 2 ( divide both sides by - 3 )

x = \frac{-2}{-3} = \frac{2}{3}

Multiple Representations Explain how to use a number line to find the
DaniilM [7]

Answer:

First, 3 units away from -7 could be, either -10 (when going to the left), or -4 (moving 3 to the right). Lastly, the opposite of the integer(s), (if opposite is meaning, if the third number is -10, then the "opposite" could be the positive number "10".? and/or the other third integer is -4, then the "opposite" could be its positive, or absolute value of the negative number, or just "4".  i.e. If given a " -4", then the absolute value of it is, +4.  Or, also can be written, |-4|, meaning, the absolute value of -4, equals +4, or 4.

Step-by-step explanation:

Draw a line straight across your paper (from left to right), then in the middle of the line, make a little mark straight up and down and label it 0 (zero).  To the right, each little mark made through the line, will be positive, and go up from zero "0" to 1, then 2, then 3, then 4, and so on... Usually making a standard size number line, mark and count up to about "10".

Next, from the middle "0", moving to the left, making small marks through the line, counting from "0", to 1, and 2 and 3 and so on, EXCEPT making all these numbers negative, until getting to "-10" on the number line.

A jar contains 8 red marbles and y white marbles. If Joan takes 2 random marbles from the jar, is it more likely that she will h
podryga [215]

Answer:

a) y </= 8 is not sufficient

b) y >/= 4 is sufficient (y is not less than 3.5)

Step-by-step explanation:

Number of Red marbles = 8

Number of white marbles = y

Total number of marbles in the jar = 8+ y

Let Pr(R) be the probability of picking red marbles

Let Pr(W) be the probability picking white marbles

Pr(R) = 8/ (8+y)

Pr(W) = 7/(7+y)

Pr(RR) = Pr(R1) * Pr( R2)

= 8/(8+y) * 7/(7+y)

Pr(RW) = Pr(R1) * Pr(W2) + Pr(W1) * Pr(R2)

= 2[Pr(R1) * Pr(W2)

= 2[8/(8+y) * y/(7+y)]

The probability of having 2 red is greater than one marble of each color.

Pr(RR) > Pr( RW)

8/(8+y) * 7/(7+y) > 2[8/(8+y) * y/(7+y)]

7/(7+y) > 2(y/(7+y)

7/y > 2

7/2 > y

3.5 > y

y < 3.5

Therefore;

a) y </= 8 is not sufficient

b) y >/= 4 is sufficient (y is not less than 3.5)

Semenov [28]

Answer:

the answer is a

Step-by-step explanation:

y = -2x +1

y = x + 5

-2x+1=x+5

-3x = 4

x= -4/3

y = -1 1/3 + 5= 3 2/3

In need of some help please.
Hatshy [7]
By the Pythagorean theorem
  50^2 = x^2 +(x +34)^2
  2500 = 2x^2 +68x + 1156
  x^2 +34x -672 = 0
  (x -14)(x +48) = 0
  x = 14 or -48

The distance from the wall to the base of the ladder is 14 ft.

7-24-25 is a Pythagorean triple. The dimensions here are double those values. It can be handy to know a few of the Pythagorean triples, as that can let you write down the answers to problems without having to go through the equations.
