Answer:

Step 3

Step-by-step explanation:

Ernesto was doing well until he got to Step 3.

Its a little mistake but that chabges up the entire problem.

Let me explain-

In Step 2: 3(y+7)-2y is showing that you must distribute the 3 to the y and the 7 however Ernesto only did that for the y.

That would be the answer, hopw this helps.

What is the sum of a-1/abc^3 + 3-b/abc^3
Lyrx [107]
The answer is\frac{a-b+2}{abc^{3} }

The expression is \frac{a-1}{abc^{3} } + \frac{3-b}{abc^{3} }

Since \frac{a}{x} + \frac{b}{x} = \frac{a+b}{x}, then:

\frac{a-1}{abc^{3} } + \frac{3-b}{abc^{3} } = \frac{a-1+3-b}{abc^{3} }= \frac{a-b-1+3}{abc^{3} }=\frac{a-b+2}{abc^{3} }

Find the amount of each payment to be made into a sinking fund which earns 5% compounded quarterly and produces S47,000 at the e
Allushta [10]

Answer:

$8,355.555

Step-by-step explanation:

Hello,

This question relates to compound interest and to solve it, we'll need to use the right formula.

C.P = P(1 + r/n)^nt

C.P = compound interest

P = principal

R = rate

N = number of times compounded

T = time

C.P = $47,000

P = ?

R = 5% = 0.05

N = 4

T = 35 years

Substituting the variables into the equation,

47,000 = P (1 + 0.05 / 4) ^ (4 × 35)

47,000 = P (1.0125) ^ 140

47,000 = P × 5.625

Divide both sides by 5.625 and solve for P

P = 47,000 / 5.625

P = $8,355.555

The initial investment was $8,355.555

How many moles of hydrogen, H2, are needed to react with 2.0 moles of nitrogen, N2
Ber [7]
The coefficients DO NOT represent mass. Moles to mole ratios in a balanced chemical reaction are equivalents. Example 1: 3 H2 (g) + N2 (g) → 2 NH3 (g) tells us that 1 mole of nitrogen will stoichiometrically react with 3 moles of hydrogen to theoretically (ideally) produce 2 moles of ammonia.

Find the slope of the line that passes through (80, 300) and (70, 500).
Paladinen [302]
Slope = (y-y)/(x-x)
= 500 - 300 / 70 - 80
= 200 / -10
= 20 / -1
= -20
