Find the value of x. B 6 X+1 D E С A x = [?]

Mathematics
1 answer:
WITCHER [35]2 years ago
8 0

Answer:

x = 2

Step-by-step explanation:

Given a line parallel to a side of a triangle and intersecting the other 2 sides then it divides those sides proportionally, that is

\frac{6}{x+1} = \frac{4}{x} ( cross- multiply )

6x = 4(x + 1)

6x = 4x + 4 ( subtract 4x from both sides )

2x = 4 ( divide both sides by 2 )

x = 2

Lemon goes to the store and buys a game station for $25. The store is running a discount of 15%. What is the price of the game s
TEA [102]

Answer:

$21.25

Step-by-step explanation:

1. Convert the 15% to a decimal by dividing by 100.     15 ÷ 100 = 0.15

2. Multiply the $25 by the decimal of 15%.                    25 × 0.15 = 3.75

3. Subtract your previous answer (3.75) from the original price of the game station.        25 - 3.75 = 21.75

4. Therefore the price of the game station after the discount is $21.75.

What is the answer for this question 7(x+4)-7=48-2x
Alex777 [14]

Answer:

x = 3

Step-by-step explanation:

7(x + 4) - 7 = 48 - 2x ← distribute parenthesis and simplify left side

7x + 28 - 7 = 48 - 2x

7x + 21 = 48 - 2x ( add 2x to both sides )

9x + 21 = 48 ( subtract 21 from both sides )

9x = 27 ( divide both sides by 9 )

x = 3

If a is an odd integer and b is an even integer, which of the following makes an odd integer?
Serga [27]

9514 1404 393

Answer:

  D.) a+2b

Step-by-step explanation:

The integers 'a' and 'b' can be any, so you can choose a couple and evaluate these expressions to see what you get. For example, we can let a=1 and b=0. For these values, the offered expressions evaluate to ...

  A) 3(0) = 0 . . . even

  B) 1 +3 = 4 . . . even

  C) 2(1+0) = 2 . . . even

  D) 1 +2(0) = 1 . . . odd

_____

<em>Additional comment</em>

These rules apply to even/odd:

  • odd × odd = odd
  • odd × even = even
  • even × even = even
  • odd + odd = even
  • odd + even = odd
  • even + even = even

Then A is (odd)(even) = even; B is (odd)+(odd) = even; C is (even)(whatever) = even; D = (odd)+(even) = odd.
