No Links PleaseThe Sum Of Two Numbers Is 147. The Difference Of The Two Numbers Is 25.What Are The Two

Answers

Answer 1
86 and 61.

x + y = 147
x - y = 25

I always found second setting that second equation up was hardest. How do I know which one comes first? You just keep them in the same order as the first math equation.

So let’s solve for x in terms of y:
x - y = 25
x = 25 + y

Then substitute that into your first equation:
x + y = 147
(25 + y) + y = 147
2y = 122
y = 61

x = 25 + y = 25 + 61 = 86

Un parallélépipède rectangle posé sur une de ses faces carrées a un volume de 252cm cube, il a une hauteur de 7. Quelle est la longueur du coté de la base carré

Answers

Répondre:

6 cm

Explication étape par étape:

Volume du parallélépipède rectangle V = l²h

l est la longueur du carré basé

h est la hauteur

Étant donné

V = 252 cm³

h = 7 cm

Remplacer

252 = l² (7)

252 = 7l²

l² = 252/7

l² = 36

l = √36

l = 6 cm

D'où la longueur du côté de la base carrée est de 6 cm

Your salary is $105,000 per year
Each month, 16% of your income is deducted for taxes?

7. What is your after-tax monthly income?

Answers

9514 1404 393

Answer:

  $7350

Step-by-step explanation:

The tax deduction multiplies your income by 1 -16% = 84%. The expression of it as a monthly amount multiplies it by 1/12. So, your monthly take-home income is ...

  $105,000(0.84)(1/12) = $105,000(0.07) = $7,350

Your after-tax monthly income is $7350.

Isaac owes \$8,100$8,100 on his credit card. The bank charges an annual interest rate of 21.9%, compounded monthly. If Isaac wants to pay off his credit card using equal monthly payments over the next 16 months, what would the monthly payment be, to the nearest dollar?

Answers

Answer:

[tex]M=\$605.58[/tex]

Step-by-step explanation:

From the question we are told that:

Issac's Debit [tex]P=\$8100[/tex]

Annual interest rate  [tex]r=21.9\%[/tex]

Number of payments [tex]n=16[/tex]

 

Generally the equation for Monthly payment  is mathematically given by

 [tex]M=\frac{Pr}{1-(1+r)^-^n}[/tex]

 [tex]M=\frac{1800*0.0219}{1-(1+0.0219)^-^{16}}[/tex]

 [tex]M=\$605.58[/tex]

Therefore Payment for each month is given as

A new car sells for $34,500. If the car depreciates at a rate of seven and a half percent each year, how much will the car be worth in five years?

Answers

Answer:

$23356.5

Step-by-step explanation:

Given data

Cost =  $34,500

rate= 7.5%

Time= 5 years

The expression for the depreciation is

A= P(1-r)^t

substitute

A= 34500(1-0.075)^5

A= 34500(0.925)^5

A= 34500*0.677

A=$23356.5

Hence the worth will be $23356.5
