two step equations 12=18-d
Answer:
In this exercise, you need to get d:
12 = 18 - d
What we can do is substracting 18 in both sides:
12 - 18 = 18 - 18 - d
-6 = -d
And then, we can say that d = 6..

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

3x-4y=11
3x+2y=2
please help, I need to find what the answer is for x and y
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.
Hope this helps, thank you !!

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.
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?
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)
d=0.48688
Luis wants to buy a skateboard that usually sells for $79.08. All merchandise is discounted by 12%. What is the total cost of the skateboard if Luis has to pay a state sales tax of 6.75%. Round your intermediate calculations and answer to the nearest cent.
Answer:
$74.96
Step-by-step explanation:
$79.80 × 0.12 = 9.576 (discount)
$79.80 - $9.576 = $70.224
$70.224 × 0.0675 = 4.74012 (add for sales tax)
$70.224 + $4.74012 = $74.96412

How many quarts will you get if you mix 5 gallons 5 quarts and 6 pints
Answer:
28
Step-by-step explanation:
There are 4 quarts in a gallon, and since we have 5 gallons that gives us 20 quarts. Then we add the 5 quarts to give us 25 quarts. Finally, there are 2 pints in quart, so that gives us 3 quarts. Add those last three quarts and we get 28 quarts in all.
Total quarts when you mix 5 gallons 5 quarts and 6 pints is, 28 quarts
We have to given that,
To find total quarts if you mix 5 gallons 5 quarts and 6 pints.
Since, 1 gallon = 4 quarts
Hence, 5 gallons = 5 x 4 = 20 quarts
And, 1 pints = 1/2 gallons
Hence, 6 pints = 6/2 gallons
= 3 gallons
So, Total quarts when you mix 5 gallons 5 quarts and 6 pints is,
20 + 5 + 3
28 quarts
Therefore, Total quarts when you mix 5 gallons 5 quarts and 6 pints is,

What is the opposite of this integer: 180,000
Answer:
-180000
Step-by-step explanation:
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?
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
