Write out the subtraction in the proper order.  You subtract -3n-7 FROM n+4.  Thus, you must write n+4 FIRST.  Next, insert a subtraction sign (-), followed by (-3n-7).  MUST include those parentheses!

Here's what you should get:  n + 4 - (-3n-7).  Now remove the parentheses, changing signs where necessary:

n+4+3n+7.  combine like terms (that is, combine the "n" terms and then combine the two numerals 4 and 7.

Write out your final result below.

A 10-ft vertical post casts a 14-inch shadow at the same time a nearby cell phone tower cast a 119-ft shadow. How tall is the ce
Yakvenalex [24]

Answer:

The cellphone towers height is 1020 ft.

Step-by-step explanation:

This question is solved using proportions, by a rule of three.

A 10-ft post casts a 14-inch shadow.

Each feet has 12 inches, which means that a post with 10 feet will cast a 14/12 = 1.167 ft shadow. How tall is the cell-phone tower with a 119-feet shadow?

10 feet post - 1.167 ft shadow

x feet tower - 119 feet shadow

Applying cross multiplication:

1.167x = 10*119

x = \frac{1190}{1.167}

x = 1020

The cellphone towers height is 1020 ft.

What is 500000 and 60000000 as a decimal
Juliette [100K]

The only way to make a decimal out of either of those numbers is to write a decimal point with some zeros after it.

500,000  =  500,000.000

60,000,000  =  60,000,000.00000

etc.
