Solve for x: 18 over 10= x over 12 Prove your answer in the show your work box.<br> Pls hurry
alexandr1967 [171]

i'm doing cross-multiplication for this problem:

\frac{18}{10}=\frac{x}{12}     multiply 18 · 12, which is 216

\frac{216}{10}=x     divide 216 ÷ 10, which is 21.6

21.6 = x, is the final answer

Write the equation in standard form using integers y=4x+5
Taya2010 [7]
Unsure of what y ou want!  y = 4x + 5 is already in slope-intercept form.  If you want "standard form," which looks like Ax + By + C = 0, then identify A, B and C from the given equation y=4x+5.    Rewrite this as -4x + 1y - 5 = 0, so that A=-4, B=1 and C= -5.  This is the eqn in standard form.

How do you solve 8x+5=3x+15
sladkih [1.3K]
8x + 5 = 3x + 15

8x - 3x = 15 - 5   (put same kinds of number on one side and change the signs)

5x = 10 (simplify)

5x/5 = 10/5 (simplify)

x = 2 (answer)

hope this helps

6x+3(4x-2)=5(2x-8) the answer is -17/4 but can someone explain how to get that answer? plz help lol​
Sergeu [11.5K]

Answer:

<h2>x =  -  \frac{17}{4}</h2>

Step-by-step explanation:

6x + 3(4x - 2) = 5(2x - 8)

Expand the terms in the bracket and simplify

That's

6x + 12x  - 6 = 10x - 40 \\ 18x - 6 = 10x - 40

Using the subtraction property subtract 10x from both sides of the equation

18x - 10x - 6 = 10x - 10x - 40 \\ 8x - 6 =  - 40

<u>Add 6 to both sides of the equation</u>

8x + 6 - 6 =  - 40 + 6 \\ 8x =  - 34

<u>Divide both sides by 8</u>

\frac{8x}{8}  =  -  \frac{34}{8}

<u>Reduce the fraction with 2</u>

We have the final answer as

x =  -  \frac{17}{4}

Hope this helps you

A destroyer on patrol spots an aircraft at an altitude of 10,000 ft and an angle of elevation of 20⁰. How far is the aircraft fr
Reika [66]

sin= \frac{opp}{hyp} \\\\sin (20) = \frac{10000}{hyp}\\\\hyp= \frac{10000}{sin(20)} \\\\hyp= 29238 ft

The aircraft is 29238 ft from the ship

//

Note: this is based on my assumption that we are looking for the hypotenuse.

If we are looking for the adjacent side, then the answer would be 27475 ft.
