Answer:
6 and 18
Step-by-step explanation:
a+b=24
5a-b=12
5a+a=6a
24+12=36
6a=36 so A on it's own is 6
24-6=b
b=18
hope this helps!
Answer:
21 and 26 totaling 47sticks
Step-by-step explanation:
Th number of sticks form an arithmetic progression
1, 6, 11, 16...
The nth term of an arithmetic progression is expressed as;
Tn = a+(n-1)d
a is the first term = 1
d is the common difference
d = 6-1 = 11-6 = 5
n is the number of terms
The next two terms are the fifth and sixth term
T5 = 1+(5-1)5
T5 = 1+4(5)
T5 = 1+20
T5 = 21
T6 = 1+(6-1)5
T6 = 1+5(5)
T6 = 1+25
T6 = 26
Hence the number of sticks needed in the next two piles are 21 and 26 totaling 47sticks
Answer:
-5x(x-6)(x+7)
Step-by-step explanation:
Answer:
11x+2y+21 x = 15
2x+3y+6z = -29
13x+9x+2x =22
Step-by-step explanation:
This is an augmented matrix
It is the coefficients of the variables and the last number is the constant
11x+2y+21 x = 15
2x+3y+6z = -29
13x+9x+2x =22
