Answer:
Step-by-step explanation:
22a) width = 3x-1
2(3x-1)
6x-2 = length
22b) P = 2* length + 2* width
P= 2(6x-2) +2(3x-1)
P= 12x -4 +6x-2 ; 18x-6
22c) P = 18(5)-6
P = 84 cm
4.15
+ 2.15
=6.30
That’s the answer
<span>the expression </span>qs + 5 has two terms (qs) and (5), <span>so this is a binomial</span>
Answer:
Mean=9.75
Median = 9.5
Mode = 8,9,10,12
Range = 6
Step-by-step explanation:
Arrange number in ascending order;
6,7,8,8,9,9,10,10,11,12,12,15
Mean = sum of terms/number of terms
=(6+7+8+8+9+9+10+10+11+12+12+15)/12
=117/12
=9.75
Median = middle number in a list; since we have two numbers we add them together and divide by 2
= (9+10)/2
= 19/2
=9.5
Mode = 8,9,10,12 (multimodal) this is when there are more than one mode
Range = highest number - lowest number
=15-9
=6
Answer:
one solution: x = 5/7
Step-by-step explanation:
3 (x - 2) + 7x = 0.5 (6x - 2)
3x - 6 + 7x = 3x - 1
10x - 6 = 3x - 1
-3x -3x
7x - 6 = - 1
+ 6 + 6
7x = 5
/7 /7
x = 5/7
