Answer:
The answer is 17
Step-by-step explanation:
To find the answer, we first have to put the values in for a and b.
√225 + ║2 - 3(1/3)(4)║
√225 + ║2 - 4║
√225 + ║-2║
√225 + 2
15 + 2
17
Answer:
x=-4/7
Step-by-step explanation:
We are given an equation as
6(x+7)+4=-8(x-5)-2
and asked to solve for x
Simplify to get
Distribute 6 over x+7 and on right side -8 over x-5
6x+42+4 = -8x+40-2
Take -8x to left side to become +8x and 46 to right side to become -46
Grouping like terms
14x = 38-46 = -8
Divide by 14
x = -8/14 = -4/7
Since this is an equation, we get a single value for x
and answer is -4/7
Use the substitution method
5x+18x
5(6)+18(6)
30+18(6)
Mutiply first then add
30+108
= 138
Answer: 138
Pattern #1: (I think it should have started with 7, not 17)
7 -> 14 either added 7 or multiplied by 2
14 -> 8 subracted 6
8 -> 16 either added 8 or multplied by 2
16 -> 10 subtracted 6
10 -> 20 added 10 or multiplied by 2.
The pattern seems to be multiply by 2, then subtract 6, repeat.
14 -> 28
28 -> 22
Pattern #2:
11 -> 13 added 2
13 -> 16 added 3
16 -> 20 added 4
20 -> 25 added 5
25 -> 31 added 6
31 -> 38 added 7
to finish...
38 + 8 = 46
46 + 9 = 55
