                                       so for this equation, I would do 7/8 = 72/x
1     72
-  =   -               
8     x

Cross multiply to get 72 * 8 = 1x
solve for X                   576 = x

Any number that can be written as a ratio of two integers
adoni [48]

Answer:

Rational number

Step-by-step explanation:

Any number that can be written as a ratio of two integers is a rational number.

In the question, you have the keyword 'ratio', meaning a comparison between two numbers.  For example 1.5 can be expressed as the ratio between 3 and 2 (3/2), as a fraction.

<u>When a number cannot be expressed as a fraction, it's called an irrational </u>number. <u> The most famous irrational number of all would be pi (π). </u> You cannot express pi in a ratio between numbers, because it's  too complicated, it's basically an infinite number without any periodicity.

∠ 1 and ∠ 2 are complementary angles, if ∠ 1= 3x+10 and ∠ 2 = 4x-25. Find the measurement of ∠ 1 and ∠ 2
viktelen [127]

Answer:

<1 = 55 degrees and <2 = 35 degrees

Step-by-step explanation:

Sum of complementary angles is 90.

<1 = 3x + 10

<2 = 4x - 25

3x + 10 + 4x - 25 = 90

7x - 15 = 90

7x = 105

x = 15

<1 = 3(15) + 10

<1 = 55

<2 = 4(15) - 25

<2 = 35
