10x - 4y = 5 (if it requires shorten)
Step-by-step explanation:
x + y/5 - 1 = y - x
<=> (5x + y - 1.5)/5 = 5(y - x)/5
<=> 5x + y - 5 = 5y - 5x
<=> 5x + 5x + y - 5y = 5
<=> 10x - 4y = 5
Answer:
Common ratio = 3/4
Step-by-step explanation:
The nth term of a geometric progression is given by
an = a1 . rn - 1
Where;
an = the nth term
a1 = the first term
r = common ratio
n = the number of terms in the series
Common ratio, r = the ratio of the second term to the first term
= a2 : a1
Given from the series,
a2 = 48
a1 = 64
Common ratio, r = 48 : 64
= 48/64 = 3/4
1. distributive property
2. commutative property (the order of 8x and -24 is swapped)
3. reflexive property ((8-24) = -16; -16 is substituted for 8-24. I prefer "substitution property".)
4. commutative property (the order of 8x and -16 is swapped)
5. distributive property
C because if you solve for the solutions for the quadratic, then you get 5 and -1 but you cant have negative seconds so 5 is the right answer!
Answer:
D.
Step-by-step explanation:
You can set up and equation to solve for any cost like so:
5x + 20 = c
5x is the price for each hour
20 is the fixed fee
c is the total cost
Now let's use the price given to solve:
5x + 20 = 50
Subtract 20 from each side:
5x = 30
Divide each side by 5:
x = 6
