Answer:
THE ANSWER IS 2.67
Step-by-step explanation:
x = 15°
The angle of a straight line is 180°.
37 + 9x + 8 = 180
9x + 45 = 180
9x = 135
x = 15°
Answer:
Step-by-step explanation:
h and p are the number of history and psych textbooks, respectively.
store sold a total of 411 textbooks in a week.
h + p = 411
The number of history textbooks sold was 69 less than the number of psychology textbooks sold.
h = p - 69
Substitution
(p-69) + p = 411
2p = 411+69
p = 240
h = p-69 = 171
171 history books and 250 psych books
The circumference of a circle can be found by multiplying pi ( π = 3.14 ) by the diameter of the circle.
If a circle has a diameter of 4, its circumference is 3.14*4=12.56.
If you know the radius, the diameter is twice as large.
Answer:
<h2>4</h2><h2>11</h2>
Step-by-step explanation:
20:5=4 (minutes for 1 meter)
4*11=44 minutes for 11 meters
or
20 : 5 = x : 11
x = 20*11:5
x = 44
or
20:5* 11=44
