Answer:
13.
Let us say
first angle be = 4x -10
second angle = x
now add them to 90 as complementary angles add up to 90
4x - 10 + x = 90
5x - 10 = 90
5x = 90+10
5x = 100
x = 100/5
x = 20
the first angle = 4x -10
= 4(20) -10
= 80 -10
= 70
the second angle = x
= 20
the angles are 70 and 20
Answer:
1) -3/3
2) 1/2
3) 3/4
4) -2/1
5) 1/2
6) 4/1
Step-by-step explanation:
<u>RISE OVER RUN</u>
(Rise) Using the farthest dot on the left you count how much you rise till you align with the second dot <em>(depending on whether you go up or down determines + or -)</em>
(Run) Once aligned with the second dot count whilst 'running' towards it till you've reached it.<em> (If you go right it's +, if you go left it's -)</em>
Hard to explain, but it's really easy if you look up a tutorial.
Total wages = 1
Food = 1/3
Rent = 1/5
Savings = total wages - food - rent
= 1 - 1/3 - 1/5
= 15/15 - 5/15 - 3/15
= 7/15
3 4/10 is my answer
