Answer:
102.3
Step-by-step explanation:
a_38 = -5
difference d= -2.9
We use general formula
WE make the formula for a_38 th term
Plug in 38 for n
Now plug in -2.9 for d and -5 for a_38
Now add 107.3 on both sides
102.3 = a_1
option A is correct
A common denominator is when 2 fractions have the same denominator and a common multiple is when two multiples have at least 1 number alike
Example: Common Denominator
4/10 6/10
Example: Common Multiple
2: 2,4,6,8,10,12
4: 4,8,12
Answer:
£12
Step-by-step explanation:
9.60 = 80% times y.
9.60 = 0.8y
Then, divide each side by 0.8 to get the equation in shape to solve for y.
y = 9.60/0.8
y=12
Will x mean <span>forming the plural of many </span>
Okay, let's use x for the 24 page packages and y for the 30 page packages:
x + y = 9
x = -y + 9
Now here's the second equation:
24x+30y = 258
We can input y into our second equation:
24(-y + 9) + 30y = 258
-24y + 216 + 30y = 258
6y = 42
y = 7
9 - 7 = 2, so:
