Answer:2x-14. Explanation: distribute 2 to both terms
Y
y=ax
where a is a constant of proportionality;
y=20, x=4
20=4a
a=20/4
a=5
y=5x
The constant of variation is 5
Well we could start by making common denominators so we can subtract these two fractions.
7/8 = 35/40
2/5 = 16/40.
35/40 = 16/40 = 19/40.
19/40 = 0.475.
So about 1? Not really, since it rounds down to 0.
Close to 1? Not really, since it rounds down to 0.
Exactly? No.
Step-by-step explanation:
The scientific notation:
where 1 ≤ <em>a</em> < 10, and <em>k</em> ∈ Z (integer).
Side 1+ side 2 + side 3=180 on a triangle. 180-56=124 124-66 because 124-56 =66 but X is the smaller side so 56 X=56 (i believe but could be wrong unsure I have a tendency to mess up a few calculations.)
