The test is worth 80 points.
Each homework assignment is work 25% of the test.
Question asked:
How many points may be earned during this unit ?
Solution:
By unitary method:
Points may be earned from 1 assignments = 
(given)
= 
Points may be earned from 5 assignments = 
Points may be earned from 1 test = 
Total points may be earned = 100 + 80 = 180

Answer:
Let the number be x
It say it get increased by 5,
x + 5
Then squared,
(x+5)^2
x^2 + 25
hope it helps!
Addition:
1) a + 8
2) 4 + c
3) m + 16
4) f + 20
5) T + r
Subtracting:
1) 23 - p
2) 550 - h
3) 25 - W
4) 7 - j
5) M - x
6) l - 12
Multiplication:
1) 4x
2) 20b
3) 2x
4) 3/4m
5) 7x
Division:
1) r/19
2) x/d
3) c/d
4) p/g
Mixed Practice: using x for the number unless specified
1) 1/4d + 8
2) 2x - 5
3) 7 + xy
4) 1/2x
5) m + 6n
6) m + n
7) 34/x
8) 20 - x/y
9) 6(x - 3)
10) 2(x + 8)
____________________________________________________________
1) n + 4
2) 4n
3) n - 4
4) n + 4
5) n - 4
6) 4n
7) 5n + 6
8) 5n - 6
9) 2n - 9
10) n/7
11) n(n + 7)
12) n(n - 7)
13) 2n - 8 = 14
14) 3n - 1 = 7
15) 5n + 4 = n - 2
16) n - 10 = 6n + 3
17) 2(n + 3) = 20
The best measurement would be D. Metres.
Answers
H= - 2/5
Step-by-step explanation:
3h - 2( 1 + 4h)
3h - 2 + 8h
-2+8h-3h
-2 + 5h
5h=-2
H= - 2 /5
