Please help me 2x-7/8+x=2x+7/2+5

Mathematics
1 answer:
Elina [12.6K]3 years ago
8 0

Answer:

x = \frac{75}{8}

Step-by-step explanation:

So we have this:

2x - \frac{7}{8} + x = 2x + \frac{7}{2} + 5

First, let's combine like terms:

3x - \frac{7}{8} = 2x + \frac{7}{2} + \frac{10}{2} \\3x - \frac{7}{8} = 2x + \frac{17}{2}

Next, let's move variables and numbers each onto their own sides to get our answer:

3x - \frac{7}{8} + \frac{7}{8}  = 2x + \frac{17}{2} + \frac{7}{8}\\ 3x = 2x + \frac{75}{8} \\3x - 2x = 2x + \frac{75}{8} - 2x\\\ x = \frac{75}{8}

How is the number five and two hundred three thousandths written in standard form?
Andru [333]

Answer:

0.05203*10 to the power 2

Step-by-step explanation:

To get the standard form you divide a number in order to multiply it by a power of 10 to get the same number. So 5.203 in standard form is o.o5203 * 10 to the power 2. The 10 to the power 2 comes from the number of palces you move the comma/ decimal point to the left

Four times a number added to 3 times a larger number is 31. Seven subtracted from the larger number is equal to twice the smalle
notka56 [123]

Answer:

Let x represent the smaller number and y represent the larger number

<u>For the first equation </u>

Four times a number added to 3 times a larger number is 31 is written as

4x + 3y = 31

Making y the subject we have

3y = - 4x + 31

Divide both sides by 3

That's

y =  -  \frac{4}{3} x +  \frac{31}{3}

<u>For the second equation</u>

Seven subtracted from the larger number is equal to twice the smaller number is written as

y - 7 = 2x

Making y the subject

We have

<h3>y = 2x + 7</h3>

Hope this helps you

Which function f (x) , graphed below, or g (x) , whose equation is g (x) = 3 cos 1/4 (x + x/3) + 2, has the largest maximum and
Leya [2.2K]

Answer:

g(x), and the maximum is 5

Step-by-step explanation:

for given function f(x), the maximum can be seen from the shown graph i.e. 2

But for the function g(x), maximum needs to be calculated.

Given function :

g (x) = 3 cos 1/4 (x + x/3) + 2

let x=0 (as cosine is a periodic function and has maximum value of 1 at 0 angle)

g(x)= 3 cos1/4(0 + 0) +2

    = 3cos0 +2

     = 3(1) +2

     = 3 +2

     = 5 !
