Distribute the 1/3 to the y and the 2
So... (1/3)*y and (1/3)*2
(y/3)+(2/3)+3x=7x
Now subtract 3x from both sides
(y/3)+(2/3)=4x
To get rid of the 3 on the bottom of the fractions, you can multiply both sides by 3 so they cancel out.
y+2=12x
Subtract 2 from both sides to get an equation of
y=12x-2
Answer:
3.75 miles / hour
Step-by-step explanation:
120 steps / minute * 2.75 feet / step * 60 minutes / hour * 1 mile / 5280 feet =
3.75 miles / hour
Answer:
S₁₅ = 645
Step-by-step explanation:
The sum to n terms of an arithmetic sequence is
= [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
Using the nth term formula = 5n + 3 , then
a₁ = 5(1) + 3 = 5 + 3 = 8
a₂ = 5(2) + 3 = 10 + 3 = 13 , then
d = a₂ - a₁ = 13 - 8 = 5
Thus
S₁₅ = [ (2 × 8) + (14 × 5) ]
= 7.5( 16 + 70)
= 7.5 × 86
= 645
Using the graphing you graph the two equations and then find the point where the two lines of the equation meet.
Hope this helps :)
