What is the answer to -20+5p-7z

1 answer:

6 0

" -20 + 5p - 7z " is not a question, and it doesn't beg for an answer.
It's an expression that stands for a number.

In order to determine what the number is, you need to know the
values of 'p' and 'z'. And if either of those changes, then the value
of " -20 + 5p - 7z " immediately changes too. So the whole thing is
a 'moving target'.

Answer:

$3.98(estimated)

Step-by-step explanation:

3c (cake) + 2(2c - 11) (bread) = 5.87

3c + 4c - 22 = 5.87

7c - 22 = 5.87

7c = 5.87 + 22

7c = 27.87

c = 3.98

Using Triangle Similarity Theorems (6)

Fantom [35]

Answer:

DC = 3

Step-by-step explanation:

Based on triangle similarity theorem, we would have the following equation:

$\frac{AD}{AC} = \frac{AE}{AB}$

Plug in the values

$\frac{9}{9 + DC} = \frac{12}{12 + 4}$

$\frac{9}{9 + DC} = \frac{12}{16}$

$\frac{9}{9 + DC} = \frac{3}{4}$

Cross multiply

3(9 + DC) = 9×4

27 + 3DC = 36

Subtract 27 from each side

3DC = 36 - 27

3DC = 9

Divide both sides by 3

DC = 9/3

DC = 3

-2x - 10 = 4

combine the like terms

-2x = 4 + 10

-2x = 14

divide by -2

-2x/-2 = 14/-2

x = -7
