Answer:
a = 5
Step-by-step explanation:
If it's easier for you, you can replace n(a) with y and put a as x.
Now the equation is y = 7x + 4.
It asks you to put in 39 as y.
39 = 7x + 4.
To solve this, the goal is to isolate the variable on one side. The first step I see is to subtract the 4 from both sides.
35 = 7x
Now divide both sides by 7 and we're done!
5 = x
5/6 divided by 3/7?
simple mi amigo!~
7* 5= 35
3*6= 18
= 35/18
= 1 17/18
Step-by-step explanation:
6.5 / 0.5
= 6.5 / (1/2)
= 6.5 * (2/1)
= 13.
Since 13 is unequal to 3.25,
we conclude 6.5 / 0.5 = 3.25 is false.
The ratio of circumference to diameter is independent of the radius.
Defining C=circumference, r=radius, D=diameter = 2r
Circumference = C = 2 π r = π D
=>
ratio of circumference / diameter
= C/D = π
Answer:
A
Step-by-step explanation:
14/15 is less than 7/5
