Can someone solve this? and tell me how?
maksim [4K]

Answer:

1/3

Step-by-step explanation:

When working with balanced expressions (stuff on both sides of the equal sign), "what you do to one side, you do to the other", which keeps it balanced.

The first thing we notice is the exponent 1/4, which is one both sides, so we can get rid of it on both sides by using the <u>reverse operation</u>.

The reverse of exponents is <u>square root</u>.

(4x + 10)^{\frac{1}{4}} = (9 + 7x)^{\frac{1}{4}}\\\sqrt[\frac{1}{4}]{(4x + 10)^{\frac{1}{4}}} = \sqrt[\frac{1}{4}]{(9 + 7x)^{\frac{1}{4}}}\\\\4x + 10 = 9 + 7x

Isolate x to solve. Separate the variables and non-variables.

4x + 10 = 9 + 7x

4x - 4x + 10 = 9 + 7x - 4x          Subtract 4x from both sides

10 = 9 + 3x                

10 - 9 = 9 - 9 + 3x            Subtract 9 from both sides

1 = 3x            Divide both sides by 3 to isolate x

x = 1/3           Answer

-5=5(d+4)<br> Please give step by step
bekas [8.4K]

Answer:

  1. first distribute the 5 to the d and 4
  2. 5(d+4) then becomes 5d+20
  3. then subtract 20 from both sides of the equation
  4. -5=5d+20 is now -25=5d
  5. lastly divide 5 from both sides
  6. -25=5d is now -5=d
  7. hope this helps!

4. Cross multiply (10•6) (15•n) 15n=60 you do the opposite operation so instead of multiply 15•n you divided 15 from n. And what u do on one side u do on both. So divide 15 from 60 and u get 4.

Julie has 50$ which is eight dollars more than twice what john has. How much does john have
nydimaria [60]

Answer:

John has $21.

Step-by-step explanation:

Let John's "wealth" be w.  Then 2w+8 = 50, or 2w = 42, or w = 21.

John has $21.  Eight more than twice this is 42+8 = 50, as expected.
