Okay so lets look at what it says.

Opposite in the case of math almost always means negative.  So (2(-n)+5)*2.  This can be simplified to (-2n+5)*2 = 22 + n

Again, simplify it and its -4n+10 = 22 + n

Subtract 10 from both sides and its -4n = 12 + n

Add 4n to both sides and you get 0 = 12 + 5n

Subtract 12 from both sides and its 5n = -12.

Divided both sides by five and you have n = -12/5

Choices are... <br> A)1120<br> B)2275<br> C)3500<br> D)2345<br> It's Side Splitter Theorem
sergiy2304 [10]

Answer:

B

Step-by-step explanation:

The sections of the parallel roads split by the transversals are in proportion, that is

\frac{350}{300} = \frac{first}{1650} ( cross- multiply )

300 first = 577500 ( divide both sides by 300 )

first = 1925 ft

Thus

Elm st → Maple st = 1925 + 350 = 2275 ft → B

HELP......................................
djyliett [7]

Answer:

The equation's result: 32,000 (Rounded)

Goal: Find the closest or equivalent result in another expression

Step-by-step explanation:

<h3>A)</h3>

(1.5^{15})/(0.7^{12})\\(1.5^{15})/(0.7^{12}) = (437.894)/(0.7^{12})\\437.894/(0.014)\\31636.79

How we got to 31,636 was by dividing from left to right.

Remember: When dividing decimals, it's like multiplying whole numbers in a way. The number(the quotient, also) ends up bigger instead of being smaller like when dividing whole numbers. If you multiply decimals, they(the product) end up smaller.

Therefore, A is the correct answer.

What is the value of x?
blsea [12.9K]
Since these are supplementary angles  (two angles which sum to 180°) we can say:

4x+x=180  combine like terms on left side

5x=180  divide both sides by 5

x=36°
