56 + 34 = n + 30

    90    = n + 30     <em>added like terms on the left side (56 + 34)</em>

<u>    -30    </u>  <u>     -30  </u>    <em>subtracted 30 from both sides to isolate n</em>

    60    =  n

You're on the right track. Start by combining like terms on the left side of the equation by adding 56 and 34.

90 = n + 30, now subtract 30 from both sides of the equation to isolate the variable n.

60 = n is the answer.

Please help with math

Answer:

2nd option, x > 1.10

Step-by-step explanation:

7e^{2x}-5 > 58

Add 5 to both sides,

7e^{2x}-5+5 > 58 +5\\7e^{2x} > 63

Divided both sides by 7,

\frac{7e^{2x}}{7} > \frac{63}{7}

e^{2x} > 9

Apply Exponent Rule,

2x > 2ln(3)

\frac{2x}{2} > \frac{2ln(3)}{2}

x > ln(3) or x > 1.09861

What is the solution to the equation 1/4x+2=-5/8x-5
Fed [463]

multiply everything by 8

2x+16 = -5x-40

-16 on both sides

2x = -5x-56

+5x on both sides

7x = -56

x=-8

so the first option

Answer:

112.065

Step-by-step explanation:

so divide the triangle in two from x to wy

and you get to triangles

then using the first right angled triangle you can apply tan=opposite/adjacent

to get height as 7.56 then apply 1/2bh to get first area as 58.59

first add all angles and subtract from 180=24

then use tan to get the height as 6.9

then apply 1/2bh to get second area as 53.48

then add the two areas to get total

(after getting first one don't multiply by two)
