True or false : <br> 20÷4x5= 1<br> 10+10÷2=15<br> 6+4×5=50<br> 12_3×2=6<br> 81÷9+2=11
ELEN [110]
To solve, you must use order of operations. The acronym used is BEDMAS (brackets, exponents, division/multiplication, addition/subtraction), which is the order you solve in. 

F  20÷4x5
    =5x5
    =25
      
T   10+10÷2
      =10+5
      =15

F    6+4×5
      =6+20
      =26

<span>T   81÷9+2
     =9+2
     =11</span>

An angle measures 2° less than the measure of its complementary angle. What is the measure of each angle?
Ahat [919]

Answer:

  angle: 44°

  complementary angle: 46°

Step-by-step explanation:

Complementary angles have a sum of 90°. We can use this relation and the one given to write equations for the angles of interest.

__

<h3>setup</h3>

Let 'a' and 'c' represent the angle and its complement, respectively.

  a = c -2 . . . . . an angle is 2° less than its complement

  a +c = 90 . . . . complementary angles total 90°

<h3>solution</h3>

Using the first equation to substitute for 'a' in the second, we have ...

  (c -2) +c = 90

  2c = 92 . . . . . . add 2, collect terms

  c = 46 . . . . . . . divide by 2

  a = 46 -2 = 44 . . . . find 'a' using the first equation

The angle is 44°; its complement is 46°.
