5(3x+4y) is equivalent to 15x-20 !
Answer:
22. 3/8
23. 3/5
24. 0
Step-by-step explanation:
turn the 1 into a fraction for each of the problems.
for 22. it would be 8/8 because also trying to make the denominators the same.
8/8 - 5/8 = 3/8
try 23 and 24 now!
Answer:
Associative property of addition
Step-by-step explanation:
The associative property of addition is as follows :
a+(b+c) = (a+b)+c
We have,
a = 8, b = 9 and c = 3
So,
Using above property,
(8+9)+3 = 8+(9+3)
20 = 20
Hence, this is the required solution.
The negative sign isnt changing back and forth, so its not a geometric sequence
the difference between each term looks to be constant at 10
a1= 3
a2=-7= a1-10
a3= -17 =a2-10
oh look a pattern
an= a(n-1) - 10
Answer:
y = 2x
Step-by-step explanation:
There is a proportional relation between the number of pairs of socks that Jason buys,x, and the total cost (in dollars), y.
Let us assume that the relation is y = kx ..... (1)
{Where k can be assumed to be the constant of proportionality}
Now, given that Jason can buy 2 pairs of socks for $4.
So, from equation (1), we can write 4 = 2k, ⇒ k = 2
Therefore, the equation (1) becomes y = 2x. (Answer)
