4. Find the value of x. (4x - 10)

Mathematics
1 answer:
Solnce55 [7]2 years ago
6 0

Answer:

<h3>x = 20°</h3>

Step-by-step explanation:

We know,

The angle of a straight line is 180°

therefore,

  • 90 + (4x - 10) + x = 180°
  • 5x = 180 - 90 + 10
  • 5x = 190 - 90
  • 5x = 100
  • x = 20°

Answer:

5.625

Step-by-step explanation:

So first do 112 / 360

Simplify it = 28 / 90 = 14 / 45

So 1.75 is 14 / 45 of the circumference.

The whole circumference is 1.75 * (45 / 14)

So the answer is 45 / 8 = 5.625

Two pairs of statements about Jeff's housing expenditures are given below. How can both pairs of statements be true?
Irina18 [472]

Explanation:

Pair 1 is true if Jeff's monthly income is $600/20% = $3,000.

Pair 2 is true if Jeff's monthly income is $1200/10% = $12,000.

Both pairs can be true if Jeff's monthly income increased by a factor of 4 in the 20 years from 1990 to 2010.

Obviously, Jeff spent more on housing in 2010. (Fortunately for Jeff, that larger expenditure was a smaller fraction of his income.)
