Answers

Answer:

awijd iawjd aw

Step-by-step explanation:

dwa dawd awgw

well it’s not a or b because that’s cutting 1/2 to an even smaller number;

1/2x4/5= 0.4, less than 1/2 or 0.5
1/2x1/2= 0.25 also less than 1/2 or 0.5

it’s not c either because 1/2x1/1 is just multiplying it by itself still being 1/2.

so d is the only answer because 1/2x5/4= 0.625 which is more than 0.5 or 1/2

Furniture at IKEA is on sale for 35% off of the original price. If the original price of a sofa is $500, how much will you pay at the discounted price?

SHOW YOUR WORK FOR FULL CREDIT.

Answers

Answer:

$175

Step-by-step explanation:

10% of 500 you know is 50

so if you add 10% 3 times you know that that's 30% and its easy to add.

50+50+50= $150

than you add the 5% and how you get 5% if you split the 10% in half. Half of 50 is 25 so therefor if you add 10+10+10+5= 35% and if you add 50+50+50+25= $175

-2(x+7)= x-34+2x i need the steps

Answers

♡ The Question ♡

・-2 (x + 7) = x -34 + 2x

*୨୧ ┈┈┈┈┈┈┈┈┈┈┈┈ ୨୧*

* ♡ The Answer ♡

・x = 4

*୨୧ ┈┈┈┈┈┈┈┈┈┈┈┈ ୨୧*

♡ The Explanation/Step-By-Step ♡

・-2 (x + 7) = x -34 + 2x

-2 (x + 7) = x + 2x - 34

-2 (x + 7) = 3x - 34

-2 (x + 7) : -2x - 14

-2 (x + 7)

Apply the distributive law! : a(b + c) = ab + ac

a = -2, b = x, c = 7

= -2 + (-2) x 7

Apply minus (-) plus rules!

+ (-a) = -a

= -2x - 2 x 7

Multiply the numbers! : 2 x 7 = 14

= -2x - 14

-2x - 14 = 3x - 34

Add 14 to both sides!

-2x - 14 + 14 = 3x - 34 + 14

Simplify!

-2x = 3x - 20

Subtract 3x from both sides!

-2x - 3x = 3x - 30 - 3x

Simplify!

-5x = -20

Divide both sides by -5!

-5x/-5 = -20/-5

Simplify! : -5x/-5 : x

Apply the fraction rule! : -a/-b = a/b

= 5x/5

Divide the numbers! : 5/5 = 1

= x

Simplify! : -20/-5 : 4

-20/-5

Apply the fraction rule! : -a/-b = a/b

= 20/5

Divide the numbers! 20/5 = 4

= 4

x = 4

Larry invests $100 in a savings plan. The plan pays 5 1/2% interest each year on
his $100 account balance. The following chart shows the balance on his account
after each year for the next 5 years. He did not make any deposits or
withdrawals during this time.

Answers

Answer:

100*1.055^5 = $130.70

Step-by-step explanation:

the simple way to work this out is to think about how much the savings increase by each year.

Balance * (1+interest)^years

So convert the interest rate to decimals and add it to one. This is the amount the balance is multiplied by each year. Raise it to the power of the years of interest and you get the result.

For 5 years it is

100*1.055^5 = $130.70
