The length of a rectangle is 4 inches longer than it is wide. If the perimeter is 52 inches, what are the
dimensions of the rectangle?
Answers
Answer:
L = 15
W = 11
Step-by-step explanation:
P = 2L + 2W
2L + 2W = 52 Divide each term by 2
2L/2 + 2W/2 = 52/2
L + W = 26 Substitute the value for L
W + 4 + W = 26
2W + 4 = 26
2W = 26 - 4 Subtract 4 from both sides
2W = 22 Divide by 2
W = 22 /2
W = 11
L = W + 4
L = 11 + 4
L = 15

Simplify the expression 2(10) + 2(x-4)
Answers
Answer:
Hello! :) have a good day!
2x + 12
Answer:
First: Multiply the numbers
2 x 10 + 2 (x -4)
20+2(x-4)
Secondly: Distribute
20+2(x-4)=
20 + 2x - 8
Thirdly: Subtract the numbers
20 + 2x - 8=
12 + 2x
Lastly: Rearrange terms
12 + 2x
2x + 12
And that would leave us with our answer 2x + 12!

Answers
Answer:
I have attached a picture of me solving the equation.
Now you must be wondering how I got the answer, well first simplify the expression in y = mx + b. Then graph it on demos. Do the same thing for the other expression. Pick any point that lies on the line. That is your solution to the equation.
The green line is the expression of 3x - 4y = 11. I simplify the equation in y = mx + b giving me y = 3/4x - 11/4.
The orange line is the expression of 3x + 2y = 2. I simplify the equation in y = mx + b giving me y = -3/2x + 1.

There are 510 calories in 100 g of Twix.
There are 45 calories in 100 g of Coca Cola.
Lionel has 60 g of Twix and 140 g of Coca Cola for a morning snack
Work out the total number of calories in this morning snack.
Answers
Answer:
Amount of calories in 60g of Twix and 140g of Coca cola = 1020 calories
Step-by-step explanation:
Given:
Amount of calories in 100 g of Twix = 510 calories
Amount of calories in 100 g of Coca cola = 45 calories
Find:
Amount of calories in 60g of Twix and 140g of Coca cola
Computation:
Amount of calories in 60g of Twix = 60[510/100]
Amount of calories in 60g of Twix = 306 calories
Amount of calories in 140g of Coca cola = 140[510/100]
Amount of calories in 140g of Coca cola = 714 calories
Amount of calories in 60g of Twix and 140g of Coca cola = 306 + 714
Amount of calories in 60g of Twix and 140g of Coca cola = 1020 calories

For the equation: D = -0.306c + 0.9979, what is the value of D when c= 1.67? Express answer with the correct number of sig figs?
Answers
Answer:
0.48688Step-by-step explanation:
Let's solve your equation step-by-step.
d=(−0.306)(1.67)+0.9979
Step 1: Simplify both sides of the equation.
d=(−0.306)(1.67)+0.9979
d=−0.51102+0.9979
d=(−0.51102+0.9979) (Combine Like Terms)

Answer:
its $63.96
Step-by-step explanation:
Using the formula (b) and replacing the given values:
Sale Price = Original Price - Amount Saved. So,
Sale Price = 79.95 - 15.99
Sale Price = $63.96 (answer).
This means the cost of the item to you is $63.96.
You will pay $63.96 for a item with original price of $79.95 when discounted 20%.
In this example, if you buy an item at $79.95 with 20% discount, you will pay 79.95 - 15.99 = 63.96 dollars.
Answer:
$63.96
Step-by-step explanation:
$79.95 = 100%
The jacket is on sale for 20% off, therefore it is 100% - 20% = 80% or 0.8
0.8 x $79.95 = $63.96

A store sells hardcover books for $8 and paperback books for $5. You buy 9 books, represented by the equation x+y=9, where x is the number of hardcover books and y is the number of paperback books. The equation 8x+5y=51 represents the total cost. How many of each type of book did you buy?
Answers
Answer:
Step-by-step explanation:
x+y = 9
y = 9-x
8x + 5y = 51
8x + 5(9-x) = 51
8x + 45 - 5x = 51
3x = 6
x = 2
y = 9-x = 7

Answers
Answer:
$74.96
Step-by-step explanation:
$79.80 × 0.12 = 9.576 (discount)
$79.80 - $9.576 = $70.224
