50 is the value cause 20 is 40 of the percent, 20+20 is 40 now you made it into 80%.20% is remaining so add 10.
Answer:-
The question ain’t ryt dude,
I will answer as soon as u correct it
What a wack question, confused on either he spent that 7 or didn't. But imma say he didnt so, i think 8$ if thats even an answer, spent half his allowance and earned 7 dollars and ended off with 15 at the end of the week. So that means 8 doesn't it?
Step-by-step explanation:
<span> we know the length of the cable is 9m.
That means the magnitude of </span><span><span>r<span><span><span>AB</span></span><span></span></span></span>=9</span><span>m.
The unit vector, denoted u, is each of </span><span>r<span><span><span>AB</span></span><span></span></span></span><span> divided by the magnitude.
</span>u=<span>(<span><span>x/9</span><span></span></span>i−<span>y/9<span></span></span>j−<span>z/9<span></span></span>k<span>)
</span></span><span>We can also figure out the unit vector of F.
</span>u=(350i - 250j - 450k)/√(350² +(-250)² +(-450)²)
u=0.562i−0.401j−0.723<span>k
</span>
<span>Force F is directed from point A to B, then both unit vectors must be equal.
Therefore
</span>(x/9i−y/9j−z/9k)=0.562i−0.401j−0.723k
<span>We can now solve for each term
x/9=0.562----- > x=5.058 m
-y/9=-0.401--------- > y=3.609 m
-z/9=-0.723------- > z=6.507 m
The answer is
the coordinates of point a
(5.058,3.609,6.507)

Answer:
x = 2.
Step-by-step explanation:
Let the number be x.
Write it as an equation :-
6x - 3 = -1x + 11
6x + 1x = 11 + 3
7x = 14
x = 2.
