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

Please be sure to mark brainliest if this satisfies your question.

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

If an investor invests $24,000 into two bonds, one that pays 4% in simple interest, and the other paying 2% simple
Anettt [7]

Answers:

2% bond: $11000

4% bond: $13000

========================================================

Explanation:

x = amount invested in the 4% bond

y = amount invested in the 2% bond

Amounts are in dollars

The two amounts add to $24,000 so

x+y = 24000

y = -x+24000 is one equation to set up

0.04x = interest earned from the 4% bond

0.02y = interest earned from the 2% bond

0.04x+0.02y = total interest earned = $700

0.04x+0.02y = 700 is another equation to set up

------------

The system of equations is

\begin{cases}y = -x+24000\\0.04x+0.02y = 700\end{cases}

Apply substitution. Solve for x.

0.04x+0.02y = 700

0.04x+0.02(-x+24000) = 700

0.04x-0.02x+480 = 700

0.02x= 700-480

0.02x= 220

x= 220/(0.02)

x = 11000

Use this to find y

y = -x+24000

y = -11000+24000

y = 13000

I needs help please, a step by step answer
trapecia [35]

Answer:

68

Step-by-step explanation:

Pythagorean theorem: a²+b²=c²  a²=32²   b²=60²   c²=hypotenuse²

32²+60²=c²

1024+3600= c²

4624=c²

Now, take the square root of both sides of the equation to find c

\sqrt{4624}=c

68=c
