Step-by-step explanation:
the sequence is arithmetic due to the common difference that is equal
d=11-15=7-11=-4
a(n) = a1 +(n-1)d
a1=15
Then :
a(n) = 15+(n-1)-4
hope this helps
Answer:
x = -6
Combine like terms.
5x + 6 = -24
Subtract 6 from both sides.
5x = -30
Divide by 5 on both sides.
2/3
12/6=2
18/6=3
so
the fraction is 2/3
i think this is what your teachers means, lmk if thats wrong
6
We can obtain the greatest common factor by listing the factors of the 2 numbers, that is
Factors of 18 are 1, 2, 3, 6, 9, 18
Factors of 42 are 1, 2, 3, 6, 7, 14, 21, 42
The common factors are 1, 2, 3, 6
The greatest common factor is 6
Answer: 2 4/9
The decimal equivalent is 2.44
It may help to convert the fractions to decimals. Divide the numerator by the denominator.
2 3/8 is 2.375
2 1/8 is 2.125 etc.
Remember that absolute value is considered positive. Then put the numbers in order.
54
8(11 - 3) - 2(4 + 1)
11 - 3 = 8
4 + 1 = 5
8(5) - 2(5)
8 * 5 = 64
2 * 5 = 10
64 - 10 = 54
