-2.097+0.1069x+0.2466*62=32 = x=(188078/1069)

Try converting decimals into fractions

I won't give you the exact answers, but I will give you hints that you should use to EASILY solve them.

Remember:                 (ex: Sin(D)=\(\frac{9}{15}\Rightarrow\boxed{\frac{3}{5}}\))

Sine Ratio is \(\frac{Opposite}{Hypotenuse}\)

Cosine Ratio is \(\frac{Adjacent}{Hypotenuse}\)

Tangent Ratio is \(\frac{Opposite}{Adjacent}\)

Also remember:              (ex: Csc(D)=\(\frac{1}{\frac{3}{5}}\Rightarrow\boxed{\frac{5}{3}}\)

Secant is \(\frac{1}{Cosine}\)

Cosecant is \(\frac{1}{Sine}\)

Cotangent is \(\frac{1}{Tangent}\)

Lets say x=1

So now the question is : "What percent of 5 is equal to 1/5"

Multiply 5 by 20 so it is 100, it is easier to find the percentage when it is 100. Also multiply 1/5 by 100 too.

Now what percent of 100 is 4? 

The answer is obviosuly 4%

You incorrectly multiplied by lw,

it should be lw+w^2=l^2

You also CAN'T subtract l^2

That is pretty ingenious and is better than what I did!

Based on my past answer of 54 (you posted the same question earlier and I incorrectly answered 54), I noticed that there are only 2 cases that don't fit.

So 54 - 2 = 52

So 52 is the answer?

1. Simple pattern recognizing.

Remainder of when divided by 5- 

7^1=2

7^2=4

7^3=3

7^4=1

7^5=2

and so on

This means the remainder pattern is 2, 4, 3, 1,

To find the remainder of 7^2019, we find the remainder of 2019 divided by 4 because there are 4 terms in the pattern.

Since the remainder is 3, we count up 3 times in the pattern.

So the remainder of 7^2019 divided by 5 is 3.

x can represent the total gallons of gasoline.

This means that when it was \(\frac{1}{8}\)full, it is \(\frac{1}{8}\)x.

So this means \(\frac{1}{8}x+15=\frac{3}{4}x\)

Solving we get 24 gallons in the entire tank.

It is currently three-quarters full, which is 18 gallons out of a total of 24 gallons.

This means we need \(\boxed{6}\) more gallons to fill the tank.
