13 + 21 = 13- -21
The minus sign and negative cancel each other out.
Model the problem as the following: 44x+x=90
where x equals the smaller of the two angles. Then, simplify to: 45x=90
Divide by 45 to get x=2
Then input 2 into the equation to get the angles 2° and 88°
Answer:
see explanation
Step-by-step explanation:
(a)
9n =
- 2 ( multiply through by 7 to clear the fraction )
63n = 15 - 14 = 1 ( divide both sides by 63 )
n = 
(b)
= k - 4 ( multiply through by 3 to clear the fraction )
1 = 3k - 12 ( add 12 to both sides )
13 = 3k ( divide both sides by 3 )
= k
(c)
g -
g = 3 ( multiply through by 5 to clear the fraction )
5g - 2g = 15
3g = 15 ( divide both sides by 3 )
g = 5
(d)
w + 2w = 3 ( multiply through by 7 to clear the fraction )
3w + 14w = 21
17w = 21 ( divide both sides by 17 )
w = 
Number 1. is 1/5 but in decimal form it’s 0.2
Answer:
A) 30 pages
Step-by-step explanation:
No of pages = 75
Aman coloured 60 % of the pages= 75 *60/100= 45
Prakash coloured 75 - 45 = 30 pages
