Answer:

The person can correct this error two ways.  The first is by multiplying every part of the right side by 8 instead of only the \frac{y}{8}:

8(4) = (\frac{y}{8} + 1)(8)\\32 = y + 8\\24 = y

Another way to fix it is to subtract 1 from both sides before multiplying both sides by 8.

4 - 1 = (\frac{y}{8} + 1) - 1\\3 = \frac{y}{8} \\8(3) = \frac{y}{8}(8)\\24 = y

Answer:

Step-by-step explanation:

4=y/8+1

rewrite equation

y/8 + 1 = 4

move all terms not containing y to the right of the equation

y/8 = 3

multiply both sides of the equation by 8

8 x y/8 = 8 x 3

simplify both sides of the equation.

y = 24

Help on this one please
kvv77 [185]

Answer:

d ≈ 1732 ft

Step-by-step explanation:

Angle of elevation = Angle of depression

Following this truth,

m∠PAQ (Angle of depression) = m∠APB (Angle of elevation) = 30°

By applying tangent rule in the given triangle ABP,

tan(30°) = \frac{AB}{PB}

\frac{1}{\sqrt{3}}=\frac{1000}{d}

d = 1000√3

d = 1732.05

d ≈ 1732 ft

I NEED HELP!!!!!! 4x+2x-5=7x-1
yan [13]

Let's solve your equation step-by-step.

4x+2x−5=7x−1

Step 1: Simplify both sides of the equation.

4x+2x−5=7x−1

4x+2x+−5=7x+−1

(4x+2x)+(−5)=7x−1(Combine Like Terms)

6x+−5=7x−1

6x−5=7x−1

Step 2: Subtract 7x from both sides.

6x−5−7x=7x−1−7x

−x−5=−1

Step 3: Add 5 to both sides.

−x−5+5=−1+5

−x=4

Step 4: Divide both sides by -1.

−x

−1

=

4

−1

x=−4

Answer:

x=−4
