Find each product.<br> 1) (5n - 5)(4n - 4)

Paraphin [41]

Answer:

20n² - 40n + 20

Step-by-step explanation:

(5n - 5)(4n - 4)

= 5n(4n) + 5n(-4) - 5(4n) - 5(-4)

= 20n² - 20n - 20n + 20

= 20n² - 40n + 20

Another way to do this:

(5n - 5)(4n - 4)

= 5(n - 1) * 4(n - 1)

= 20(n - 1)(n - 1)

= 20(n - 1)²

= 20(n² - 2n + 1)

= 20n² - 40n + 20

a recipe uses 1 1/4 cups of milk to make 10 servings. if the same amount of milk is used for each serving, how many servings can

Anestetic [448]

Answer:

128 servings can be made using 1 gallon of milk.

Step-by-step explanation:

Given that:

$1\frac{1}{4}$ cups of milk make 10 servings

$1\frac{1}{4}$ can also be written as 1.25

Ratio of cups of milk to servings = 1.25 : 10

1 gallon = 16 cups

Let,

x be the number of servings made from 1 gallon

Ratio of cups of milk to servings = 16 : x

This is a direct proportion

1.25 : 10 :: 16 : x

Product of mean = Product of extreme

10*16 = 1.25x

160 = 1.25x

1.25x=160

Dividing both sides by 1.25

$\frac{1.25x}{1.25}=\frac{160}{1.25}\\x=128$

Hence,

128 servings can be made using 1 gallon of milk.

Which is a correct first step in solving the inequality –4(2x – 1) > 5 – 3x?distribute –4 to get –8x 4 > 5 – 3x.distribute

Leviafan [203]

Answer:

Option A is correct.

The first step in solving the inequality is:

to distribute -4 to get $-8x + 4> 5-3x$

Step-by-step explanation:

The distributive property says that:

$a\cdot(b+c) =a\cdot b + a\cdot c$

Given the inequality:

$-4(2x-1)> 5-3x$

Apply the distributive property we have;

$-4 \cdot (2x) -4\cdot (-1)> 5-3x$

Simplify:

$-8x + 4> 5-3x$

Therefore, the first step in solving the inequality is:

to distribute -4 to get $-8x + 4> 5-3x$

sukhopar [10]

Let the total candy bar be represented by x.

Amount of chocolate Kaitlyn gave to Arianna = $\frac{1}{2}x$

Amount of chocolate Arianna gave Cameron

= $\frac{1}{3}$ rd <span>of the candy she got from Kaitlyn to Cameron

= </span> $\frac{1}{3}$ × $\frac{1}{2}x$

= $\frac{1}{3}* \frac{1}{2} x = \frac{1}{6} x$

Hence, Cameron got $\frac{1}{6}$ th of the original chocolate.
