Answer 1

Answer:

(7) n = ⁴/₃

(8) x = -5

(9) d = ³/₂

(10) v = -20

Step-by-step explanation:

(7) [tex]n-\frac{8}{9} = \frac{4}{9}[/tex]

[tex]n-\frac{8}{9} = \frac{4}{9} \\\\Collect \ similar \ terms \ together\\\\n = \frac{4}{9} + \frac{8}{9} \\\\n = \frac{4+8}{9} \\\\n = \frac{12}{9} \\\\n = \frac{4}{3}[/tex]

(8)

[tex]\frac{3}{2} + \ x = -\frac{7}{2}\\\\collect \ similar \ terms \ together\\\\x = -\frac{7}{2} -\frac{3}{2} \\\\x = \frac{-7-3}{2} \\\\x = \frac{-10}{2} \\\\x = -5[/tex]

(9)

[tex]\frac{6}{5} = \frac{d}{(\frac{5}{4} )} \\\\cross \ and \ multiply\\\\5d = 6(\frac{5}{4} )\\\\5d = \frac{30}{4} \\\\d = \frac{30}{4\times 5} \\\\d = \frac{30}{20} \\\\d = \frac{3}{2} \\\\d = 1\frac{1}{2}[/tex]

(10)

[tex]-\frac{1}{8} v = \frac{5}{2} \\\\\frac{-v}{8} = \frac{5}{2} \\\\cross \ and \ multiply\\\\-2v = 40\\\\-v = \frac{40}{2} \\\\-v = 20\\\\v = -20[/tex]

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:

0.48688

Step-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)

A walkway is described as "a tunnel or path for strolling along, especially. a raised hallway connecting separate sections of such a building or perhaps a wide path inside a park or garden" in the New English American Dictionary.

HELP ASAP PLS!!! ONLY HAVE 10 MINUTES LEFT TO FINISH

Answers

Answer:

Step-by-step explanation:

The graph gave us two points: (5,0)(0,1)

Let’s find the slope!

1-0/0-5

slope is 1/-5

y=-1/5x+b

Choose one point and plug it into x and y

1=-1/5(0)+b

1=0+b

b=1

y=-1/5x+1

Answer:

y=-1/5x+1

Step-by-step explanation:

Write an equation in slope-intercept form that describes the relationship between the number of minutes, x, and the amount charged, y.​

Answers

Answer:

y = 1/20x + 6

Step-by-step explanation:

The number of minutes is your x-value. The amount charged is your y-value.

Let's convert the numbers in the table into coordinates.

(30, 7.5)

(120, 12)

(220, 17)

Now, we will take two points and use the slope formula to plug into the slope-intercept equation: y = mx + b

I chose the first and last points given. All three points do not lie on the same line, but using the first and last point should be closer to the line of best fit.

(30, 7.5) & (220, 17)

m = (y₂ - y₁) / (x₂ - x₁)

m = (17 - 7.5) / (220 - 30)

m = (9.5) / (190)

m = 0.05 = 5/100 = 1/20

m = 1/20

Plug m into your equation.

y = 1/20x + b

To find b, plug in a point for x and y.

17 = 1/20(220) + b

17 = 11 + b

b = 6

Plug b into your equation.

y = 1/20x + 6

Hope this helps!

How many quarts will you get if you mix 5 gallons 5 quarts and 6 pints

Answers

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,

28 quarts.

Someone please help me I’ll give out brainliest please dont answer if you don’t know

Answers

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

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

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

In this exercise, you need to get d:
