5/8x + 2 = 57/16 hurryy

Mathematics
1 answer:
Shtirlitz [24]3 years ago
5 0

Answer:

x = \frac{5}{2}

Step-by-step explanation:

Given

\frac{5}{8} x + 2 = \frac{57}{16}

Multiply through by 16 to clear the fractions

10x + 32 = 57 ( subtract 32 from both sides )

10x = 25 ( divide both sides by 10 )

x = \frac{25}{10} = \frac{5}{2}

anzhelika [568]

Answer:

N*B*x/100

Step-by-step explanation:

To determine an equation of the total number of dollars, it is necessary to review the variables that influence

The most important, N that would be the number of shares of A.

The other variable is B, since it would be the price of the shares that were purchased.

Lastly, we have x, since he originally had was A's shares, therefore his increase occurred in A's shares, that is, x.

Therefore, the equation would be:

N * B * x / 100

It is divided by 100 since x is a percentage.

23. The letters of the alphabet are written on
Alla [95]

Answer:

21/676

Step-by-step explanation:

The total number of letters of the alphabet will be the total outcome which is 26 alphabets.

If consonant numbers are drawn out, the probability of drawing a consonant will be total consonants/total alphabets

Total consonants in the alphabet is 21.

Probability of drawing consonants = 21/26.

Since all the consonants are replaced before drawing a Z, our total outcome will not change i.e it will still be 26.

Probability of drawing a letter Z will be 1/26.

Therefore, the probability of drawing a consonant,replacing it, and then drawing a Z will be;

21/26×1/26

= 21/676

When all the variables cancel out in an equation, how do you know if there are no solutions or infinite solutions?
Ivahew [28]
If a number equals the same number, there are infinite solutions
Example: 5=5, which is true, so there are infinite solutions
If a number equals a different number, there are no solutions
Example: 5=2, which isn’t true

PLZ help picture included
cupoosta [38]

Answer:

4 miles

Step-by-step explanation:

Let

x ----> the time to returned back biking in hours

d ---> the distance in miles

s ---> speed in miles per hour

Remember that

The speed or rate is equal to divide the distance by the time

s=\frac{d}{t}

The distance is equal to multiply the speed by the time

d=st

we know that

18\ min=\frac{18}{60}\ hours

The distance to his friend's house and the distance of return is the same

so

10x=4(x+\frac{18}{60})

solve for x

10x=4x+\frac{18}{15}

subtract 4x both sides

10x-4x=\frac{18}{15}

6x=\frac{18}{15}

x=\frac{1}{5}\ hours

The total distance of the round trip is

y=10x+4x+\frac{18}{15}

substitute the value of x

y=10(\frac{1}{5})+4(\frac{1}{5})+\frac{18}{15}

y=2+2=4\ miles
