Answer:
105 degrees
Step-by-step explanation:
You first add 5 and 7 which gives you 12. Then, since two supplementary angles add up to 180, you divide 180 by 12 which gives you 15. Next, since 7 is the larger of the two, multiply 7 by 15 giving you 105. To check your work, subtract 105 from 180 giving you 75. Next, put this as a fraction- 75/105 and simplify giving you 5/7 which can also be written as 5:7.
Answer:
2
Step-by-step explanation:
Change in y over change in x
From 2 to 8 is 6
Fdom 6 to 9 is 3
6/3 is 2
To find the average of a group of numbers you add them all up and divide by how many there are.
2+3+6+8+4=23
23/5=4.6
so your average is 4.6
We will call the unknown number <em>x</em>.
<em /><em>x</em> - 2 1/4 - 1/8(3) - 2/3(2) = 3 11/24
<em>x</em> - 2 1/4 - (1/8)(3/1) - (2/3)(2/1) = 3 11/24
<em>x</em> - 2 1/4 - 3/8 - 4/3 = 3 11/24
We need a common denominator. 24 is the first number that 4, 8 and 3 all both divide evenly into.
<em>x</em> - 2 6/24 - 9/24 - 32/24 = 3 11/24
<em>x</em> - 2 15/24 - 32/24 = 3 11/24
<em>x</em> - 2 47/24 = 3 11/24
<em>x</em> - 3 23/24 = 3 11/24
Cancel the 3 23/34 by adding to both sides:
<em>x</em> - 3 23/24 + 3 23/24 = 3 11/24 + 3 23/24
<em>x</em> = 6 34/24 = 7 10/24 = 7 5/12
