Answer:

8c - 7r + 10p - 20e

Step-by-step explanation:

Subtract (20c + 15r + 75p + 50e) - (12c + 22r + 65p + 70e)

(20c + 15r + 75p + 50e) - (12c + 22r + 65p + 70e)

Open bracket

20c + 15r + 75p + 50e - 12c - 22r - 65p - 70e

Collect like terms

= 20c - 12c + 15r - 22r + 75p - 65p + 50e - 70e

= 8c - 7r + 10p - 20e

Find the midpoint of the segment with the given endpoints. (1/4,-4/9) and (-5/2,1/2). 21 points help me out
nlexa [21]

Answer:

(-9/8, 1/36)

Step-by-step explanation:

Midpoint Formula: (\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )

Step 1: Find midpoint <em>x</em>

x = (1/4 + -5/2)/2

x = (-9/4)/2

x = -9/8

Step 2: Find midpoint <em>y</em>

y = (-4/9 + 1/2)/2

y = (1/18)/2

y = 1/36

Step 3: Write midpoint coordinates

(-9/8, 1/36)

Whats 1 1..........................................?
olasank [31]
<span>It depends on the number system and the defined operation.

In simple addition we get 1+1=2
In group theory, provided a binary operation as addition modulo 2 is defined, we get (1+1) mod 2 = 0

Answer:

\frac{5}{6}

Step-by-step explanation:

3 \frac{1}{2} - 2 \frac{2}{3}

\frac{7}{2} - \frac{8}{3} First change the two mixed numbers to improper fractions. Multiply the whole number by the denominator then add the numerator to the answer.

\frac{21- 16}{6} Bring the fractions to the same denominator by finding the lowest common multiple of both denominators

Then the answer becomes \frac{5}{6}.
